Bringing the ruined smartphone back to life. Samsung: custom recovery is not installed (CWM, TWRP) After installing twrp, the phone does not turn on

Sooner or later, we all want something new and interesting, even if it concerns the firmware on a smartphone. It's time to replace the standard, long-boring picture with something more original. But smartphone owners are interested in the question of how to install TWRP Recovery on Xiaomi. The fact is that many users on "you" communicate with various applications, and even changing the firmware for them is something like a feat.

Here's a tip - before thinking about the firmware, it doesn't hurt to make changes to the recovery. Many forums advise you to pay attention to TWRP, pointing out that TWRP has one distinctive feature Is stable and comfortable work... Moreover, there is an opportunity to work on touch control, which is very beneficial. In general, we will figure out how to install TWRP on Xiaomi.

To use this method, you need to have root rights. Since we are considering Xiaomi, advanced users already have the rights here, it remains only to transfer them to the application. If there are no rights, then you need to get them, and only then install the recovery.

Further instructions are as follows:

Go to Google play(https://play.google.com/store/apps/details?id=com.jmz.soft.twrpmanager&hl=ru) and find a suitable application there;
Install it and run it;
When the application is installed, you must agree with everything that the application offers, grant it root access, etc.;
Select your device and download the Xiaomi TWRP file by clicking on "Download TWRP";
Next, select the downloaded img file and through the key "Flash to recovery" install it.

After the program is installed, the mode will turn on reboot to recovery mode, that is, reboot. But after that, all manipulations can be carried out from this menu without completely changing the system. And who is afraid that the stock firmware will fly off, then when correct work it won't happen.

Installing Mi Recovery via fastboot

The second method, how to enter Recovery, is no longer so simple, but with sufficient concentration and attentiveness, it can also be mastered by an ordinary user who decides to dig a little deeper than the standard smartphone settings. The only thing that really does not hurt here is the skills of using the console and ADB.

Disable driver digital signature verification

For Windows 8

Press the combination of buttons "Win + I"... Crawl out on the right "Options".
Clamp "Shift" and click.
After rebooting, a window will appear "Choice of action"... We choose "Diagnostics" -> "Extra options" -> Boot options -> "Reload".

After rebooting, we will see the window " Restart options " push "F7" and wait for the Windows to reboot.

For Windows 7

When turning on the computer, after the stage BIOS boot, we often press "F8"... A menu will appear "Additional download options"... Choose Disable Required Driver Signing.

P.S: F8 does not always work the first time, so if it doesn't work, you can either repeat it 2-3 times, or resort to an alternative method.

Process description

The first step is to download and install the drivers and download and unpack them. It is very important that the file path is not in Chinese. You can use only Latin characters, otherwise the system will generate an error.
The second step is to enable USB debugging. This is the simplest procedure. It consists in the following manipulations: on the Xiaomi phone, you need to open the item "About the phone"... When you find the menu you want, eight times (sometimes seven is enough) click on the MIUI version. After clicks, a message will appear "You are a developer"... A sub-item "for developer" will appear in the settings menu and select "USB debugging" in it. If there is nothing, then you do not have access rights or you already have one.
In the third step, login and run command.bat from the ADB folder. Next, we indicate the command "Adb devices" but after checking if there is a smartphone connection. If the phone does not respond, then something is wrong, therefore it is better to connect again.
If the connection is established, start Fastboot Mode by running the command "Adb reboot bootloader» ... Once this is done, the smartphone will automatically reboot and enter bootloader mode. When it is over, you can install custom recovery.
Since we do not have the recovery itself, in this case I use the recovery files that are on the Internet, download them on the forums, etc. For example, you can find Mi Recovery 3 at this link. You need to save the recovery in the folder with adb and name it TWRP.img
And using the installation is generally very simple, since its whole essence boils down to one simple command "Fastboot flash recovery TWRP.img".

In fact, this is where it all ends, although in order to make sure that the device is working properly, you need to enter the TVRP mode from the device. Launching is pretty straightforward. To do this, you should perform the following manipulations:

Press and hold the power and volume buttons in the "down" position;
We wait for the vibration signal and immediately leave;
We are waiting for the utility that we just installed to start.

If all is well, you can go to the system, and if your goal is to install the firmware, then continue working.

Problems

Of course, not everyone will be able to carry out these manipulations, but a user of an average degree of advancedness must still figure out how to work in recovery mode.

If the smartphone simply does not enter this mode, no matter what options you use, then you can look for alternative options on how to enter the desired mode. But we strongly advise against using unverified methods, because this can cause the complete collapse of your smartphone. It is much safer to entrust this business to a professional, preferably who has already dealt with Xiaomi smartphones.

The main reason that the user cannot enter the recovery is the conflict between the utility code and the firmware. Solving this trouble is simple - you can reinstall the recovery itself. But this is only a temporary solution, and then you will have to look for another way to enter the system menu of interest.

Experienced users are often interested in how you can install Recovery on Android. Recovery mode allows you to perform several additional operations on your smartphone.

There are methods that can be applied to flash custom recovery. These include ROM Manager for ClockworkMod, GooManager for TWRP, Fastboot for devices with unlocked bootloaders, and Flash Image for when other methods don't work.

Which installation method is better to choose

Most smartphones are compatible with multiple recovery modes, but the most popular are ClockworkMod Recovery (CWM) and TeamWin Recovery Project (TWRP). In addition to the ROM Manager and GooManager applications, which were created specifically for these recovery methods, other programs should also work if they are compatible with the gadget.

There are 3 standard ways to install Recovery:

ROM Manager or GooManager;
Fastboot;
Flash Image.

The ROM Manager and GooManager related methods are the easiest to install ClockworkMod or TWRP. However, these methods require Root access. If you need to install any custom Recovery using the command line, then the Fastboot method will do. The main advantage of this method is the fact that it does not even require rooting. It should be borne in mind that the bootloader must be unlocked for this method.

The Flash Image method also allows you to replace the stock Recovery and set any custom recovery mode. This requires Root permissions, a command line emulation application, and the flash_image binary. This saves the hassle of using a computer to manual installation Recover with Fastboot.

The Fastboot and Flash Image methods require a dedicated recovery image. The latest version of ClockworkMod and TWRP for a specific gadget can be downloaded from the web pages of the developers of these applications.

In some cases, you may need alternative installation methods, for example, if your smartphone does not have a separate partition for recovery mode, since it is built into the kernel boot partition. Many Sony devices fall into this category and Samsung Galaxy... They need a kernel firmware that includes recovery using ODIN or FlashTool.

An alternative method will also be needed if the device was not originally intended for Android systems... In this case, a special method for installing ClockworkMod is required. Examples include the HTC HD2 and the HP TouchPad. There is no one-size-fits-all guide that covers all the methods for setting up recovery mode, but the standard methods outlined in this guide should work for most smartphones. However, some phone models may require a specific approach, in which case you will need to refer to search engine Google to find instructions for specific devices using it.

Installing CWM Recovery

You can now go directly to the standard methods for setting up a custom recovery mode. Such operations should be performed with caution. If during the installation process the device is damaged or completely breaks down, then its owner may be denied warranty repair or replacement, since users are not allowed to engage in such manipulations.

Those who are interested in how to install ClockworkMod Recovery should take into account that this is the easiest and most affordable method, which allows you to start the installation from the graphical interface during device boot. In this case, you do not need to download the recovery image and enter any commands. This is the most convenient method for most users. You can try other methods only if CWM did not work. To install CWM Recovery, follow these steps:

Install ROM Manager on your smartphone. This is an application that allows you to schedule recovery operations during Android boot and has the option to install the latest version of ClockworkMod Recovery.
Launch the newly installed ROM Manager. The first option that the program will offer should be called Flash ClockworkMod Recovery. You must click on it and follow the instructions.
You have to wait until the system reboots and the latest version of the program is installed. Do not restart manually.
After rebooting the system and starting operating system you need to make sure with the ROM Manager that the latest version of CWM Recovery is installed. Everything available updates Should be installed. In case of occurrence new version you must install it following the instructions.

other methods

Install TWRP Recovery using GooManager:

Install GooManager on your gadget. This application allows you to install firmware and mods posted on the official Goo website, as well as latest version TWRP Touch Recovery.
Launch GooManager as soon as it is ready.
Enter the menu and select Install OpenRecoveryScript. Answer yes to all questions in dialog boxes and grant the application access to Root.
Wait while the program loads Last update TWRP for the device and install it.
After installing Recovery, you need to make sure that the process was successful. To do this, you need to boot through recovery mode. This can be done using the GooManager by clicking Menu and selecting the Reboot Recovery option.

And one more way how to install custom Recovery. You will need to download the most recent recovery image that fits your device from the ClockworkMod Recovery or TWRP download page.

It is very important that this file is compatible with devices of a certain brand. For example, if you are using a Digma device, you need to make sure it is supported. Otherwise, the firmware may fail and render the device unusable.

To install any custom recovery mode using fast bootloader, the computer must have ADB and Fastboot. After the installation is complete, you will need to do the following:

Copy the recovery image to any convenient location on your computer (it is desirable that the path to the file is not too long). You can put it in the root directory of the C drive and not create a special folder. The recovery image must have an IMG extension. If it is inside a ZIP archive, you should unpack it.
Connect your Android device to personal computer via USB.
Wait until Fastboot USB appears on the screen.
Launch Command Prompt and enter fastboot flash recovery c: \ recovery.img. Keep in mind that the path to the file looks like this because the image is located in the root folder of the C drive. If the image is located in a different location, you need to specify the appropriate path.
Wait until the process is complete, then restart the device.

If everything was done correctly, the modified Recovery Mode should work.

How to install recovery on Android

Today, custom recovery, that is, a recovery environment for Android devices, offers much more options than firmware. Therefore, below we will consider step by step installation using the popular TWRP (Team Win Recovery Project) as an example.

How to install recovery on Android - preparing for the firmware process

It is important to know that (in some cases, for example, when the power is turned off, discharged, disconnected from the wire), the process of installing custom recovery can lead to a decrease in the performance of the device, the appearance of errors, failures and other dysfunctions. In this case, the device loses the remaining warranty period, so all manipulations should be done with the utmost care, at your own risk. By default, it is assumed that the bootloader is already unlocked on the smartphone or tablet, and the Android SDK Platform Tools are installed. If the device meets the described conditions, do the following:

We download the appropriate version of the recovery for Android, which corresponds to the model of our smartphone / tablet.
Save the file to the Platform-tools folder with the Android SDK (you can choose any other location, but this will make it easier to specify the path for further commands).
Turn on USB debugging.

Installing third-party recovery on Android

You can now start downloading the custom recovery environment software package to your device. This order action involves the use of an operating Windows systems(version is not fundamentally important):

switch to "fastboot" mode: for some devices there may be a different sequence of pressing the buttons, but basically you need to press and hold "- sound" and the power button until the menu appears;
the next step is to connect the device via USB to the PC, after making sure that there is a sufficient amount of charge on the first device;
go through the computer to the SDK Platform-tools folder;
press Shift and click right click mouse over an empty space at the same time;
select the item "Open command window";
enter the command fastboot flash recovery recovery.img, send it for execution with the Enter button (explanation: in place of recovery.img there must be a path to the file of the same name; if it is located in the tools folder, then enter the name "as is");
after the notification of successful completion appears, the device can be turned off.

When the TWRP installation is complete, there will still be a fastboot menu on the smartphone / tablet screen. To test the just received custom:

select the item " Recovery Mode», Moving through the list with the volume buttons and confirming the actions by pressing the power supply;
after the initial login, select the language and the operating mode - read-only or "allow changes";
if you choose the first option, the custom recovery will disappear after the next reboot;
choosing the second will leave TWRP on the system partition;
you can also check the box "Do not show this again at boot".

The main custom firmware menu will allow you to flash ZIP files, install third party firmware, back up or restore files from a backup, reset to factory settings with complete destruction of data.

CWM Recovery Android - Custom Recovery Installation

Since the topic Android firmware devices is very relevant, I decided to write about installing CWM Recovery on an Android smartphone or tablet. There are several ways how to do this at once: for some, all actions are performed on the device itself, but this requires root rights, while for others, when installing custom recovery, a computer is used. Use whatever you find easier or more convenient.

Method 1. Installing CWM Recovery via ROM Manager

The first way to flash Recovery is to use the ROM Manager program, which we already talked about in the article: how to flash Android. This application has a separate item that allows you to install ClockWorkMod Recovery in a couple of minutes.

I want to note right away that ROM Manager requires root rights to work. You can read how to get them here and here.

After that go to official page https://clockworkmod.com/rommanager and see if your device is on the list of supported.

1. Now open ROM Manager and select the first item "Recovery Setup".

2. In the next window, in the "Install or update Recovery" section, select "ClockworkMod Recovery".

4. At the bottom, click on "Install ClockworkMod".

5. The download process will begin. At good internet connection, it lasts a couple of seconds.

6. At the end of the download, you will be asked to grant root access to the application. Select "Provide".

7. That's it! You will see a notification “Successfully flashed ClockworkMod recovery!”. Just click OK.

This is how easy it is to flash the CWM Recovery through the ROM Manager. Now you can open it and find new items in it that were not in the standard one.

Method 2. Install custom Recovery on Android using the FastBoot utility

All the steps described below are similar to installing TWRP Recovery: go to the article.

Now we will use the classic method of installing custom Recovery through the FastBoot utility for Windows. It is included in the Android SDK, the archive of which must be downloaded from the official site http://developer.android.com/sdk/index.html (go to the bottom of the page and download "tools_version-windows.zip"). You will also need Java and drivers (read more →).

Unzip the folder to the "C:" drive - there will be "tools" inside, and the file "android" in it. Start it up.

Select "Android SDK Platform-tools" and click "Install package".

Check the box "Accept License" and then click "Install".

When the installation is complete, “platform-tools” will appear in the “tools_version-windows” folder, and it contains “fastboot” and “adb”. They will be useful to us further.

UPD: The "platform-tools" folder on my computer is located in a different directory than yours. The fact is that this article was written even when an installer existed for the Android SDK. Starting from the 25th version, the installation is carried out only from the ZIP archive: because of this, part of the instructions had to be edited. Therefore, the path to ADB and Fastboot is different from mine, everything else remains unchanged.

If you have a Sony, HTC, Nexus, Huawei or LG device (some models), then Bootloader is blocked. How to unblock it is described on our website:

For HTC: method 1, method 2
For Nexus: instruction
For Sony: instruction

Let's start the Recovery firmware:

1. First of all, go to this page and download the version of the file "recovery-clockwork.img" for your device. Note that there is both a touch and a classic version for most devices. Download the one you like best.

2. Now place the file with the CWM recovery in the "platform-tools" folder. I also renamed it to "recovery.img" (you will see why later). I recommend that you do the same.

3. Connect your tablet or smartphone to your computer using USB.

In this case, the device must be booted into fastboot mode. Usually, to do this, on the turned off device, you need to hold down the key combination: Power on + Volume down. But this combination may differ depending on the device manufacturer.

UPD: it is much easier to switch to fastboot mode as follows: enable USB debugging on the device, go to the command line (in step 4 just below it is described how to get into it) and enter the commands sequentially, while after each press "Enter".

cd path to "platform-tools"

adb reboot bootloader

I got it like this:

Your path will look different. If you followed exactly the instructions, it will exit (in any case, see the path in the appropriate line of the Explorer):

cd \ tools_r25.2.3-windows \ platform-tools

On the screenshot you can see how I entered the same commands. As a result, the device will boot into fastboot mode.

4. Now open the command line (or skip this item and continue working with it if you just transferred Android to fastboot mode through it). The easiest way to get there: press the key combination "Win" + "R" and enter:

Then click "OK".

5. You will be taken to the command line.

6. Now you need to specify the path to the folder with the firmware. Enter the following command to navigate back to the folder.

Press Enter.

7. My path to the recovery folder is "C: \ Program Files (x86) \ Android \ android-sdk \ platform-tools". So I enter (you write yours):

cd Program Files (x86) \ Android \ android-sdk \ platform-tools

And again press "Enter".

8. It remains to enter:

fastboot flash recovery recovery.img

"Recovery.img" is the name of the file to be flashed. Remember I advised you to rename the file from recovery? We did this for convenience, so as not to enter something like "recovery-clockwork-6.0.4.7-flo.img".

After entering this command, press "Enter" again.

9. As a result, we receive the following message.

Congratulations! You have successfully installed custom recovery (CWM) using the Fastboot utility!

Method 3. Flash Recovery via the Rashr application

This method is also incredibly simple and convenient, but requires root rights. Their receipt is written at the beginning of the article in "Method 1".

1. Install the Rashr app - Flash Tool from Google Play, open it and grant Root rights.

2. Select "CWM Recovery" from the list of options.

3. Then the program will display a list of available Recovery for your device. In my case, Rashr showed 2 options: ClockworkMod with support for screen taps and classic version(controlled by volume and power buttons).

4. When prompted to download, click Yes.

5. Then the download of CWM Recovery for your Android smartphone or tablet.

6. At the end, a notification will appear that the firmware was successful and now you have a modified recovery installed. You can reboot into it and try it out. To do this, click "Yes".

Perhaps this installation method can be called the simplest. The only thing that is needed for him is the presence of root rights.

Method 4. Installing Recovery on Samsung in Odin

If you have a Samsung device, you can install ClockWorkMod Recovery on Android using the proprietary Odin utility. Here I will briefly explain what to do. I recommend reading our article: how to flash an Android tablet, Samsung smartphone. In it detailed information about using Odin.

1. Find and download recovery for your Samsung phone or tablet.

2. Connect the device to a PC via USB and put it in the download solution. How to do this is written in the full article at the link above.

3. Open Odin and click on "AP" (in some versions of Odin this field is called "PDA").

4. Click the "Start" button and wait for the firmware to complete.

That's all! Hope you found this article helpful! If you have any questions, leave them in the comments.

TWRP Recovery how to install? TWRP Recovery download for android

Hello everyone! In this article, we will talk about TWRP Recovery. Let's start with the advantages over perhaps the main rival, this is ClockworkMod, then we will consider the purpose and functionality of this utility, then we will give an extended description of all menu items. And of course, we'll figure out where to download and install TWRP Recovery. And at the end, a bonus will describe the process of flashing an android smartphone using this utility.

Before you start reading the TWRP Recovery instructions, I want to note that most of the users prefer to use this particular recovery due to the fact that, compared to ClockworkMod, it has the following advantages:

More user-friendly touch interface
Function for setting some options.
A transparent way to select what we want to include in backup
Batch installation support zip files
Lock the screen by pressing the power button
S-Pen support on tablets and Galaxy phones Note

TWRP Recovery is a much more powerful system recovery utility (menu) than the factory one, which allows you to make full backups of the entire device system, install software, firmware, kernels and much more on it, which usually does not allow factory recovery TWRP, installed in a special system partition of the internal memory of a tablet or phone, in place of the factory recovery. TWRP Recovery can help you out in some seemingly hopeless situations. Even if your tablet or phone stopped booting, in many cases, using TWRP, you can restore the system from a backup, with all its settings and applications.

Here's a rough list of what you can do with TWRP Recovery:

Install custom firmware and unofficial kernels
Install factory system updates, add-ons and fixes
Connect to a computer via USB, in removable storage mode
Create a full backup of the current firmware and its individual parts (system, settings, applications)
Recover a device from a previously created backup
Reset to factory settings (Wipe - data / factory reset), clear cache (wipe cache), clear dalvik-cache (wipe Dalvik-cache), clear battery statistics (wipe battery stats)
Create partitions on the memory card and format them
Execute terminal commands
Work with files on your device

For many smartphones and tablets, installing TWRP Recovery (download) is a fairly simple procedure, you just need to install a program such as GooManager from the Market and select “Install OpenRecovery Script” from its menu:

For many devices, such as Nexus tablets and smartphones, there are separate utilities, like the Google Nexus 7 Toolkit. Also, TWRP Recovery can be installed using the adb program.

There are several ways to load your tablet or phone into TWRP Recovery.

1. Using a special program, such as GooManager, by selecting "Reboot Recovery" - "Load Recovery Mode" from its menu.

2. By pressing a certain key combination when turning on the device. This combination depends on the device model. On many devices, you can get into recovery by pressing the volume down and power on buttons at the same time when they are turned on.

3.Using ADB programs... If you configured a connection to a computer using the ADB program, you can load your tablet into recovery using the command: adb reboot recovery

After booting your tablet or phone into TWRP Recovery, you will first of all see its main menu
Thanks to the touch interface of the recovery, it is very easy to navigate through its items and select the options you need - just click on a certain element with your finger.
In all submenus, you can return to the previous menu by pressing the return button located at the bottom (smartphone) or upper right (tablet) part of the screen.
At the top of the screen, you see the battery percentage and the current time.

The purpose of the main menu items:

1. Install - installing firmware and add-ons

This is one of the most frequently used TWRP Recovery items.
With its help, you can install both official and unofficial (custom) firmware, install kernels, themes and other software, which must be in a zip file located on the built-in memory of your device.
After selecting a file, you will be taken to the next menu, where you can choose to add the next file to the firmware queue (Add More Zips button) or start flashing the selected file using the slider located at the bottom of the screen.
The Zip Signature verifications option enables the signature verification mode of the zip file.
The Force MD5 check on all Zips option enables MD5 checksum checking for all zip files installed on the device.

2. Wipe - clear and reset to factory settings

With this option, you can clear sections such as Cache, Dalvil Cache, System, as well as reset to factory settings - Factory Reset, after which your phone or tablet will return to the state in which it was sold in the store.
You can also clear the external memory card - External Storage and internal memory - Internal Storage, clear system folder android_secure and clear battery usage statistics - Wipe Battery Stats.
As in the rest of the menu items, you will have to confirm the start of a particular operation using the slider that appears at the bottom of the screen. You can cancel the operation using the Back button.

3. Backup - creating a backup copy of the system.

Another of the most important points of TWRP. With it, you can make a complete copy of the entire tablet system, along with the data and applications available in its internal memory - the so-called Nandroid Backup.

Here you can:

Select partitions to save: System, Data, Boot, Recovery, Cache, Uboot, NVram
Find out the volume free space on media: Free Space
Enable backup compression: Enable Compression
Disable creation of files with checksums of backups: Skip MD5 generation during backup
Select a memory card for storing backups: Use external SD
Select the internal memory of the device for storing backups: Use internal storage
Set backup file name - Set Backup name button
Calculate section sizes - Refresh Sizes button

As usual, confirm your selection with the slider and TWRP will begin the backup process:

After that, you can reboot your tablet or phone - the Reboot System button, and also go back or to the TWRP main menu using the corresponding buttons.

4. Restore - restoring the system from a previously made backup.

Here you can:

Select a memory card to search for backups: Use external SD
Select the internal memory of the device to search for backups: Use internal storage

The names of the backups consist of the date and time of their creation. You can sort files by:

Ascending "Sort Ascending" name, date and size
Descending "Sort Descending" name, date and size

After choosing a backup, you will have the opportunity to:

Select the partitions (System, Data, Boot, Recovery, Cache, Uboot, NVram) that you want to recover,
Rename the backup "Rename Backup"
Delete "Delete Backup"
Enable MD5 checksum checking of backup files
You can start recovery by confirming your choice with the slider.

5. Mount - mount individual partitions, format them and mount the device as a USB drive when connected to a computer

Mounting makes partitions or folders available for use.

Items in this menu mean the following:

Mount / Unmount System - mount or unmount the system partition
Mount / Unmount Data - mount or unmount a partition with data; Mount / Unmount Cache - mount or unmount a partition with a cache
Mount / Unmoun Sdcard - mount or unmount a memory card
Mount / Unmoun Internal - mounting or unmounting internal memory

"Mount USB storage" button - connect a tablet or phone to a computer in removable storage mode

In this case, you can choose to mount:

Memory card: Use external SD

6. Settings - TWRP settings

Here you can set the default options that TWRP Recovery will use by default when creating and restoring backups, as well as when installing zip files:

Zip file signature verification: verifies the signature of a zip file
Force MD5 check for all zips: checks checksums for all zip files
Use rm –rf instead of formatting: delete files instead of formatting when cleaning partitions
Skip MD5 generation during backup: disable checksum generation during backup
Ignore image size errors during backup: Ignore file size errors during backup
The "Time Zone" button is used to select your time zone
The "Restore Defaults" button is intended to reset the settings to the default settings.

7. Advanced - additional functions of TWRP

This menu consists of the following items:

Copy Log to SD - copying the operation log to a file on the memory card.
Fix Permissions - fix file and section permissions. This item is used in order to return to the factory state the permissions to system files and folders, which can be changed by the incorrect operation of some root applications, which can lead to freezes and malfunctions of the tablet or phone.
Partition SD Card - create partitions on a memory card. This item is used to create / sd-ext and / swap partitions on the memory card. The / sd-ext partition can be used by some firmware when there is not enough internal device memory, for example, to expand the / data partition. The / swap partition is usually used to speed up Android work devices.
File Manager is a file manager. Here you can select a file and perform the following operations on it:
Copy - copy a file
Move - move a file
Chmod 755 - set permissions 755 (like all system files)
Chmod - set any other access rights
Delete - delete a file
Rename File - rename a file
Terminal Command - execute a terminal command in the selected directory in the command style adb

Also, in the Advanced section, other buttons can be placed that the developer can add when building the recovery from the source codes for a specific device.

Here you can choose the following:

System - completely restart your tablet or phone
Recovery - reboot recovery
Power Off - turn off the device.

All alternative firmware, custom kernels, crackers, add-ons, decorations, application packages that can be installed on a tablet or phone using TWRP recovery are packed as zip files.
Before installing anything on your device, do not forget to make a full backup of the current firmware, so that later you can painlessly return your tablet or phone to its original state.
Make sure your device's battery is at least 60 percent charged, preferably fully charged, and disconnect it from the computer and charger.
Copy the file that you want to flash to the device memory or to a memory card, best of all to its root, WITHOUT UNPACKING IT. Make sure that the file name consists only of Latin letters and numbers and does not contain spaces and special characters.
If you are installing a new firmware, be sure to do a complete cleaning using the "Wipe" item

Getting started with the firmware:

1. Reboot the device to TWRP recovery

2. Select the item "Install"

3. Choose:

Memory card: Use external SD
Internal Memory: Use internal storage

4. Select the zip file

5.Using the Force MD5 check on all Zips option, enable MD5 checksum checking if you have an md5 file bundled with your zip file.

6. We start the firmware, confirming the selection with the slider

You can also select up to 10 zip files to be installed at one time using the Add More Zips button or clear the list of previously selected files using the Clear Zip Queue

Installing custom recovery on Android

By default, all Android devices have a recovery mode called Recovery. With its help, you can roll back the operating system to the standard settings, install official add-ons and fixes. If this is not enough for you and you want to install third-party firmware, kernels and utilities on your device, then the factory recovery needs to be replaced with a custom one.

The most popular custom recoveries for Android are Clockworkmod Recovery (CMD) and TeamWin Recovery (TWRP). The main difference between one program and another is the presence of touch control in the latter. As for the functionality, the software offers approximately the same list of options:

Installation of unofficial patches, firmware;
Connecting the device to a PC in ADB mode and instead of a removable drive;
Formatting, creating, merging partitions in the internal memory of the device;
Clearing the software cache and battery summary;
Making backup copies of the system.

Having studied the methods below, you can easily install custom recovery on Android. You need to get Root rights before carrying out work.

TWRP installation methods

You can install TWRP recovery using special utility software developer (TWRP Manager), third-party software designed for flashing recovery, and Android Debug Bridge (ADB).

Your first step is to download TWRP Manager from the Play Store and install the application on your device. The utility must be opened to give rights to Root access. Then:

in the menu that appears on the left, select "install twrp";
a window will appear in front of you where you need to select the device and the version of the recovery that you want to install;
after selecting all settings, click “install recovery”;
program in automatic mode downloads the recovery and install it;
if you want to install a specific version of recovery that you downloaded in advance, then you need to save recovery.img and select it via the "select img file" item.

ADB as a way to flash recovery

This solution with reinstalling the recovery is suitable for advanced PC users. To carry out the manipulations, you will need an Android device, a computer and a USB adapter. First you will need to install the Android SDK with all packages along with the Google USB Driver. After that:

save the TWRP version supported by your smartphone to your computer Recovery.img;
rename the recovery file to twrp.img, save it to the root memory of your device.

Connect your device to your computer with via USB... Start the command prompt of the PC operating system (cmd in Windows). Write the following lines in it:

cd C: \ android-sdk-windows \ platform-tools \ adb;
su dd if = / sdcard / twrp.img of = / dev / block / mmcblk0p34.

Then restart your device.

CMD installation methods

You can install CMD using Rom Manager, FastBoot mode or third-party utilities for firmware recovery.

Installing CMD using Rom Manager

Download Rom Manager from the Play Store and install it on your device. Do not forget to give her Root access rights.
After starting the program, a window will appear, including several sub-items. You will need to go to the "Recovery Setup" tab.
A new window will appear. There select CMD. After that, you will need to select the device model on which the recovery will be installed.
After that, another window will appear where you must confirm your actions.

CMD installations in FastBoot mode

To reflash a device with Android in this way, you will again need to download the Android SDK, USB drivers for your smartphone / tablet. Save the recovery file from the CMD website, rename it to update.img, save it to the platform-tools folder located in the installed Android SDK directory. Then activate USB debugging mode on your Android device.

Run Command Prompt and enter the following commands:

If everything goes well, then in command line a corresponding notification will appear.

Installing CMD and TWRP via Flashify

As we mentioned earlier, they install custom recovery for Android with third-party utilities. One of them is Flashify. A distinctive feature of the program is compatibility with many models of smartphones and tablets. You need to install software on the device and allow it to use Root rights.

From the main screen of the running application, select "Recovery Image".
A window will appear in front of you with the choice of the version of the recovery and the choice of the device model (if you have not downloaded the program in advance).
After the desired version of the recovery is saved in the device's memory, click on "YUP!".
Flashify will install the program, automatically reboot the device.

Sooner or later, the standard firmware starts to get bored or buggy, which is why most of the users begin to "comb" mobile forums in search of a solution. There, an understanding comes to mind: to change the firmware, you must first reinstall the recovery. Forum users advise installing TWRP, referring to its maximum stable operation and the ability to work with touch control... Therefore, it is worth telling how to install twrp recovery on Xiaomi, what problems may arise with this and reveal options for solving them.

What is it and why is TWRP needed

In general, this is an abbreviation, and it stands for team Win Recovery Project, thereby saying what the project is: a modified recovery that allows you to do much more than factory utilities. First of all, it is installed by those who want to install custom firmware on their device, which is why the purpose of TWRP is appropriate: a full backup of the system, installation of software, firmware, kernels, full wipes and a bunch of everything that "stock" (factory) hides from the user menu.

With Xiaomi, the situation is standard: basic recovery is not suitable for installing custom firmware, because the former simply does not allow this, which is why people come to TWRP. In addition to everything previously mentioned, Team Win can fully restore the firmware from the recovery file. So, this is a great tool for those who like to play it safe: even if the smartphone “died” after changing the firmware, it can be “revived” without any problems.

In addition to such a killer feature, TWRP can provide full-fledged work with device files, creating partitions in memory, approximately like on the HDD of your desktop, connecting to a PC in flash card mode, while the system will not be required to start. It is very convenient, for example, the wipes have already been made, and no one has transferred the firmware to the memory device, which has repeatedly happened to your humble servant.

Installing TWRP Recovery

Through the official app

It's worth starting with the fact that there are several ways. The first, the simplest, is to use a proprietary application or its analogs, you just need to remember: for correct work necessary. In Xiaomi, as a rule, advanced users already have them, all that remains is to give them to the application. Otherwise, you will first have to get those same rights, after which you already think about installing a recovery.

The action itself takes place literally in a few steps:

Find an application in the vastness of Google Play;
Install it and run it;
Agree with all permissions, grant root access if it has not been done before;
Select your device and download the file using the "Download TWRP" button;
Select the downloaded img file and install it via the "flash to recovery" button.

Here, perhaps, it is worth making a reservation: the name of the IMG file must correspond to the program: usually this is recovery.img, but proprietary applications, such as TWRP, may require you to name the files in a special way. In the case of Team Win, this is twrp.img, however, before installing, you should carefully read the description of the program, where, most likely, the required name will be indicated.

After such an installation on Xiaomi Mi3, for example, the smartphone will automatically start in Recovery mode, from which all the manipulations necessary for the user will already be performed. It should be noted: the stock firmware will not "fly" when installing the custom menu in any case, and this applies not only to Xiaomi.

Via fastboot

The second method is a little more complicated: here you will need the most basic skills in working with the console and ADB, since the option is installation recovery via fastboot. Your device should be. So, the installation itself is carried out in several stages.

The first is to download the ADB drivers and unpack them. Here you should take care that the path to the file contains only Latin characters, otherwise the console will generate an error.

We install the drivers for your device, taken.
The next step is to enable USB debugging. It is very simple to do this: first, open the "about phone" item on your smartphone, after which you need to press 8 times on the MIUI version. The message "You are a developer" should appear. If this does not happen, then you either already have access to the settings for developers, or the firmware simply does not allow you to do this.
The next step will be to directly enable debugging, which is done in the settings "for developers".

Run the command.bat file from the ADB folder, run the command "adb devices" and check if the smartphone is connected correctly, for which you may need to confirm authorization on the smartphone screen. If nothing happens during such manipulations, check the device connection, reinstall the drivers. It's better to play it safe here.

Launch Fastboot Mode on your smartphone using the "adb reboot bootloader" command. After the command, the smartphone should automatically reboot and enter bootloader mode. We are now ready to install custom recovery.

Now you need to download the TWRP recovery file. Find your device and go to the "Download Links" section and select "Primary (Recommended)" there.

The whole point of the installation comes down to entering the "fastboot flash recovery twrp.img" command. It is worth noting the following: the firmware file you downloaded should be called twrp.img or recovery.img, depending on the ADB version. You can find out where you download the corresponding programs or by reading the readme file, or just try both options.

That's all, actually, installing twrp on xiaomi redmi note 3 pro (in our case) is complete. However, there is no need to rush: you need to launch the smartphone in TWRP, for which we press the power and volume keys down. We hold the power button until the vibration response, then release it and wait for the installed utility to start.

From here, you can already boot into the system or start installing custom firmware. All the methods described on the Internet are variations of the first and second described here, moreover, there is usually no description of how to enter TWRP, so there is no point in describing them once again.

Possible problems

And the problem, in fact, is only one: after the firmware, if the custom is placed on top of MIUI 8 version and newer, many users intensively googled the phrase "how to enter twrp recovery xiaomi", because the possibility of a normal login simply disappeared. This happened due to a conflict between the utility code and the firmware: the emmc_appsboot.mbn file corresponding to MIUI, overwriting which simply does not make it possible to log into tvrp.

The solution is quite simple: you can simply reinstall the recovery. There is only one nuisance: such an action will help for exactly one flashing, which is why the guys with w3bsit3-dns.com found a more reasonable and durable fix.

So, to fix the bug, you need to download this file (only suitable for redmi 3, use at your own peril and risk), turn off the phone, hold down the power and volume buttons down, connect USB cable to the phone and computer, run the file "1 run me.bat" from the archive, which, if successful, should write "OKAY. Finished ". After that, we disconnect the cable and hold both volume and power buttons for 15 seconds, wait for vibration. That's all, TWRP after such manipulations should work fine.

conclusions

You should only install the Team Win project if it is really necessary. It is extremely difficult to ruin the phone with such a thing, but it is possible. By the way, without the standard mention that you carry out all the manipulations with your devices at your own peril and risk, it will not be possible to do without. I hope we managed to convey to you information about Team Win Recovery Project and how to install it. The method, by the way, is relevant for any Redmi and Mi models, even for Mi5 and Mi5s.

A fairly common problem that many users of Samsung smartphones and tablets encounter is that custom Recovery is not installed after flashing it in Odin!

There are two types of this problem:

While flashing custom recovery in Odin, the message “…. / failed 1) ";
After successful installation and going to the Recovery menu, you find that it is not custom (CWM, TWRP), but standard;

This article aims to solve common mistakes and learn how to avoid them in the future.

Solving the problem (succeed 0 / failed 1)

This problemв can occur not only during the Recovery firmware, but also when changing the firmware to a new one or firmware of other partitions.

Why this error occurs and how to solve it:
1. The image of the downloaded recovery is not fully downloaded, or it is broken - download the custom recovery file again or download it from another site.

2. MD5 amount does not match - note that at the end of the recovery file there is an MD5 extension, it serves to verify that the file is whole / broken, but if you change at least one letter in the file name, then recovery will be considered broken. If you are sure that recovery is not broken, then remove the MD5 extension at the end of the file. 3. Error with the COM port - make sure that the MicroUSB cable is intact, not damaged, the plugs are not bent. On the computer, use only those USBs that are directly located on the motherboard, do not use USB hubs.
4. Error with drivers - update Samsung drivers, update USB driver motherboard.

5. Reboot the device every time new firmware- if the firmware was successful or not successful, restart the device, otherwise the next firmware in Odin will generate an error (succeed 0 / failed 1).

6. Make sure that the file to be flashed is for your Samsung - if you start flashing someone else's file not from your Samsung smartphone or tablet, then at least you can get an error (succeed 0 / failed 1), and at most you will break the device.

After installing custom Recovery, Standard is loaded (Recovery crashes)

You have successfully installed Recovery, but when you enter this menu, you find that there is a standard recovery instead of a custom one. This problem is due to a partial incompatibility between the firmware and custom recovery, or due to a protective mechanism. This problem is often called "Recovery crashes."

Recovery crashes

1. After running the Odin flasher, select the recovery file, uncheck the AUTO REBOOT item:

2. Then press the Start button and wait for the message that the firmware is finished - PASS and / or a filled scale: Your smartphone or Samsung tablet won't reboot, that's ok

3. Disconnect the device from the computer, if the battery in the smartphone or tablet is removable, then remove it and then reinsert it, if it is not removable, then skip this step

4. Hold down the buttons to enter Recovery and do not release until you get into it, if Samsung started to boot into a standard working state, turn it off and put it back into Download mode and repeat steps 1-4 again

The solution to the problem "Recovery flies" who has Root

If you have Root rights, and there is also a "Recovery crashes" problem, then do the following:

1. Install the Root Browser application and go to it

2. Delete the following file along the path / system / etc / install-recovery.sh

3. Restart your Samsung device and install Recovery

That's all! In this article, we examined the main reasons that can arise when flashing recovery on Android smartphones and tablets made by Samsung!
