Unable to connect to bt speaker. iTunes failed to connect with iPhone, iPad. Troubleshooting! Fixing iTunes Connection Errors

This article explains how to resolve one of the errors that pop up when connecting iPhone to iTunes. We are talking about such an unpleasant situation when iTunes was unable to connect to this iPhone.

If a message with a similar error is displayed when connecting the device to a PC, do not be upset. There are a number of steps you can take to help resolve the issue. Each method is discussed in detail below, and the causes of the problem are given.

If iTunes couldn't connect to iPhone, you need to figure out what's causing it before you can take action to fix the error. Often a way out of the situation is discovered by itself when finding out the cause.

The first thing to do is to check if the USB cable is working. This is the most common factor causing the error. The cord must be intact, it should not have suspicious kinks and damage. The most correct decision is to check the accessory on another iOS device.

It happens that iTunes cannot “recognize” the iPhone in any way due to the presence of problems in the latter. The phone may experience failures that adversely affect its functionality. The solution to the problem in such a situation is very simple: you need to restart the iOS device. It helps 99% of the time.

Sometimes the reason lies in the "stuffing" of the PC. The USB socket may be damaged. Connect the cord to a different port.

If the source of trouble is in the USB socket or its contacts, the best way out is to connect the cord to the connector located on the back of the system unit.

Software and operating system can also "fly". The source of the problems here may be hiding in the wrong start or operation of iTunes. The easiest way out of the situation is to restart the PC. As mentioned above, this primitive procedure is almost always successful.

You can make sure that the source of the trouble is a PC / laptop by connecting an iOS device to another computer.

For devices on Mac OS X

To fix the error on this operating system, the algorithm of actions will be as follows:

Disconnecting all iOS gadgets from the PC and closing iTunes.
Launch Finder, select the section to follow to the folder.
Typing in the var/db/lockdown command and hitting the input element.
Opening the "View" section and choosing to show folder items in the form of icons.
The Finder window will display a single or group of items with impressive names that include different types of characters.
Transition along the edit path and select everything. Selecting the command to move the file to the trash. When prompted, drive in the characters of the administrator password.

Opening a section of your computer.
In the pop-up window, select the service section and folder properties. Navigate to a view section and change the hidden items setting. You need to make them visible.
Pressing the consent button.
Following the path C: / Documents and Settings / All Users / Application Data / Apple.
Move the Lockdown item to the trash.

Clicking the consent element.
Opening the Apple folder by navigating to C:/ProgramData/Apple.
Erasing the Lockdown element.
Restart PC.

This will complete the operation. The iPhone should, as before, exchange data without problems.

Cleaning the iPhone

If all the methods above have been tried, but the problem has not been resolved, it remains to resort to the last option. Probably the problem is not in the PC, but in the iPhone. And this means that you need to clean the elements that prevent data exchange. Given the fact that an iOS device does not connect to a PC via iTunes, other software will be required. Suitable iFunBox or iExplorer.

You will need to disconnect your iPhone from your PC.
After updating iTunes to the most "fresh" version.
Connect the iPhone and launch the previously installed file manager and find the VAR element.
The owner of the device must copy this item and its contents to the PC.
Erase the folder and restart your iPhone. Owners of the fifth iPhone must erase a different element - iTunes_Control.
Connect the device and exchange data with iTunes.

It should be remembered that when erasing a folder, a number of elements will disappear from the iPhone. Restoring the lost is possible from a backup located on a PC. Saving a folder is a must. This will not only save the lost data, but also return them to the iPhone in case of failure.

If this method did not help, there is only one thing left - to go to the repair shop. The owner of an iPhone cannot always cope with the trouble on his own. Often, complex diagnostics of the device are required, which only a specialist can do. For example, at home it is very problematic to detect the operability of USB sockets or to flash the device. The only drawback is the high cost of repairs.

Conclusion

Before contacting a repair shop, the owner of the iPhone can try to fix the situation himself. And the easiest way to fix this error is when you connect the PC to the iPhone, the connection is not established. Usually, the device does not connect in any way due to trifling problems that are easily resolved on their own. But any actions on an iOS device must be approached as responsibly as possible so as not to damage the iPhone or its internal parts.

Then reconnect your device (iPhone) to your computer and launch the iTunes store app. With corrected services, you will receive a message from the system about permission to access information, agree by clicking "Continue". To do this, you may need to confirm the actions on the mobile device.

The main causes of the error

There are many reasons for the appearance of errors, you will have to try and find your own among several possible ones. Often the cause of the error lies in banal things like a bad connection or Windows security settings. There are more serious problems that require changes to the internal directories of the iPhone.

The main causes of the error:

Errors caused with connection problems in the iPhone or Wi-Fi network.
iTunes and iPhone conflicts with antivirus and security software, as well as the Windows firewall.
Problems caused by incorrect connection of the phone via USB to the computer.
The presence of Jailbreak (hacked iPhone) and downloaded pirated software on it.
iTunes is not installed or updated correctly.

Depending on the error, its code, as well as the last actions of the user, you can find out why the connection between the phone and iTunes is not established.

Errors from the network and Wi-Fi side

The error may appear if Windows cannot connect to iTunes, iPhone, Apple Stope, mail server, or update server. In this case, the note "An unknown error occurred" or "An error occurred while loading the software" is written in the system window.

Connection error codes, networks, Wi-Fi: 17, 1403, 1004, 1013, 1014, 1015, 3200, 3004.

Sometimes the user has nothing to do with it - problems happen on the Apple side, and then you just have to wait for the update servers to normalize. At the same time, most of the errors can be corrected using the following steps:

Error code 17 . An error with this code appears when a user with unofficial firmware from third-party developers (custom firmware) tries to change it to another one. Such actions with changing and modifying the firmware can only be performed when the phone is in DFU mode. After entering DFU mode, the problem will disappear.
Error code 1403 . The problem occurs when trying to restore an iPhone using a corrupted firmware. For a solution, you should use another download method to download the firmware, or download the firmware in another place. With undamaged files, the update will install normally, without any notifications about conflicts with the system.
Codes 3004 and 3200 . The user is not to blame for the appearance of these errors: they occur when trying to download updates in the first de hours or days after they are released. These days there is a huge load on the Apple servers, so communication and connection problems are common.
Codes 1013 , 1014 and 1015 . Appear when you try to update the version of iOS on the iPhone to an older one, or roll back the firmware to previous versions. According to Apple's policy, you can only roll back to an older system version within the first 2 weeks after an update. After that, you will not be able to roll back the system using the allowed methods.

If all of the above situations cannot be the cause of the problem, you should proceed to the next step - fix problems with the Lockdown directory.

Solving errors 0xe8000015 (0xe8000003) through Lockdown

The Lockdown directory is created after you install iTunes, the first time you connect your iPhone to your computer. The contents of the directory files give Windows the right to modify, write to, synchronize, and otherwise interact with the files on the device. Third-party firmware, jailbreaks, and hacked software greatly increase the chance of problems with Lockdown.

The directory may have a different location and other differences depending on the version of the Windows operating system. Therefore, instructions for fixing errors are slightly different for popular versions of this OS.

If the contents of the directory are corrupted and error 0xe8000015 appears, you need to reset (delete) the directory:

Completely close iTunes.
Disconnect your iPhone or other iOS device from your computer.
Open Windows Task Manager (shortcut Ctrl+Alt+Del).
Go to the "Processes" tab.
End all running processes from the list: AppleMobileDeviceService.exe, APSDaemon.exe, distnoted.exe, iPodService.exe, iTunesHelper.exe, mDNSResponder.exe.

If iTunes is closed, all 6 processes should complete without issue. You need to right-click on each process and select "End Process". The further sequence of actions depends on which version of Windows is used on the computer.

Instruction for Windows 10, 8, 7 and Vista:

Press "Start".
Enter %ProgramData% in the search bar.
Press "Enter".
Find and open the Apple folder in the search results.
Find the Lockdown folder.
Right-click on it and select "Delete" from the context menu.

AT Windows XP this directory is located at a different address and the process for deleting it is different:

Press the "Start" button.
Select "Execute".
In the window that appears, enter %AllUsersProfile% and click OK.
In the search results, find and open the Application Data folder (it can be hidden and read-only, in which case you need to select the "Show hidden files and folders" setting in Explorer).
Find and open the Apple folder.
Find the Lockdown folder and right click on it.
Select "Delete" in the context menu that appears.

If everything is done correctly, the directory will be deleted from the computer. After that, you need to do the following:

Relaunch iTunes.
Connect your iPhone (or other iOS device) to your PC.
A window will appear with the text "Do you want to allow this computer to access information on?" - you need to click the "Continue" button.
After that, a window will appear on the iOS device, where you also need to allow access.

If the problem was caused by the LockDown directory, then it is guaranteed to be solved using the instructions above. Otherwise, it remains to check why else iTunes cannot connect to this iPhone.

USB connection problems

Problems on the USB connection side also have unique error codes. From them, you can understand which of the connection components failed. An iPhone connection error, an unknown error message and its code appear on the Windows screen.

USB connection failure codes: 13, 14, 1601-1609, 2001-2011, 4005, 4013

The problem is almost guaranteed to be a connection issue if the system issues the following warnings:

The iPhone has timed out waiting for a response.
The device cannot run faster.
An unknown error occurred during synchronization.

In case of errors 13 and 14 the cable may need to be replaced. This often solves the problem if a cheap Chinese cable is used instead of the original when trying to connect the iPhone to the computer.

There are a few exceptions:

Code 13 often appears when trying to install an iOS beta from a Windows environment.
Code 14 may appear when iTunes conflicts with antivirus software.

In this case, you should make sure that the Apple software is not blocked by antivirus programs and the Windows firewall.

Exceptions and non-standard solutions

If reinstalling iTunes and the catalog does not help, you should remove all programs that function with iTunes:

Apple Application Support
Apple Mobile Device Support
Apple Software Update
Bonjour
Quick Time

After that, it makes sense to use CCleaner to clean the registry. This can be done manually:

Click "Start", "Run".
Enter regedit in the field that appears.
In the registry editor that opens, enter the names of programs and delete the results found.

It is desirable to perform such actions with sufficient experience in Windows and more than superficial knowledge of the operating system. Removing redundant registry entries can lead to numerous new errors.

You can also go to your iPhone or other iOS device and check the remaining free space: sometimes errors occur if the device has less than 1 GB of memory left. To do this, go to "Settings", "General", "Available". It may take some time for the system to display the occupied and remaining space.
