Roll back ios version 9 to 8. How to roll back iOS version on iPhone, iPad. Deactivate Find My iPhone

On iPhone and iPad, it is possible to rollback to a previous version of the OS. Traditionally, after the release of each new edition of the branded “axis”, Apple leaves this opportunity for a while. A day after the release of the cumulative update, the company is still issuing certificates for iOS 9.2.1.

Released on March 21, iOS 9.3 is a major software release with a large list of changes. The main innovation is support for the Night Shift mode, which automatically shifts the color temperature of the display to the warm end of the spectrum at night. Studies have shown that bright blue color in the evening can affect a person's circadian rhythms, making it harder to fall asleep. Other innovations include password-protected Notes, an improved version of the Apple News app, and an updated CarPlay interface.

Judging by the comparative tests, iOS 9.3 performs better than iOS 9.2.1 in terms of performance. However, some users complain about the accelerated discharge of the battery of their devices and problems with activating gadgets. In such cases, it makes sense to use the instructions for downgrading to the previous version of the OS. Another reason why a user may decide to downgrade is jailbreak. According to preliminary information, the upcoming exploit will not be available for the latest version of the OS, at least at first.

Note that we are talking about a return only to iOS 9.2.1 - for it, Apple still issues digital certificates. The situation can change at any moment.

Requirements:

iPhone or iPad running iOS 9.3.
iOS 9.2.1 IPSW file.

Step 4: Turn off Touch ID/Password in General settings.

Each Android and iOS update has its own benefits. However, sometimes it happens that the latest version of the system has some critical flaws that are not fixed by the developer for a long time. Or a situation may arise when a new update just terribly loads a mobile device and slows down. One such unfortunate update was iOS 9.3.5.

iPad 2.

iPad 3 (iPad with Retina display).

iPad mini (1st generation).

Don't like iOS 11? Why was it updated then? … Although, this release is really special. Not everyone will go right away. Every year, Apple introduces new versions of iOS with supposedly improved features and improved optimization, but in fact, for the last couple of years, we have been “rubbed some kind of game” full of bugs and flaws.

We, in turn, find ourselves in the place of “guinea pigs”, who must identify weaknesses and point them out to Apple for further correction. What was the recent release of the nightmarish iOS 9 worth when users around the world began to complain that their .

In principle, a similar situation was with the release of iOS 8 ... and 7 too. So, if something strange happens to your iPhone after the update, maybe it's not too late to rollback to a previous version of iOS. Today I will tell you how to do it.

The nuances of the update

But first, I would like to mention a couple of nuances related to iOS firmware and which you simply must know. As you already know, updating to a newer firmware is quite intuitive by clicking on one button in your phone's Settings or in iTunes on your computer.

If you want to return to a non-previous version of iOS, you must first download the firmware file with the ipsw extension from the Internet yourself, and then install it by connecting your phone to a computer.

If you suddenly decide that you can now install any old firmware, I will have to upset you. See how the situation is. During the installation of any version of iOS, your device contacts the Apple server for a digital signature.

If the server sees a version of iOS on your device that is no longer supported, it will not sign it and the installation will fail. If you don’t understand, I’ll explain with an example: if you just installed iOS 9.0, then now you can only return to 8.4.1 and that’s not a fact. With the release of new versions of iOS, Apple stops signing older versions.

Maximum “you can take one step back”. At the time of this writing, the only current firmware for all devices since the iPhone 4S is 9.0.2.

How to find out what versions of iOS are relevant today? Very simple! We go to ipsw.me and click on the model of your device.

iOS 9.3 is a major update that brings with it quite a few interesting changes and bug fixes. However, despite all its advantages, iOS 9.3 is unlikely to be the best choice for all users now.

There are two reasons for this. Firstly, when installing iOS 9.3, many users have a problem with activating the system. You can fix it using these recommendations, but they, in some cases, cannot help. Secondly, the speed of iOS 9.2.1, especially on older devices, is slightly but higher than iOS 9.3.

Step 1. Download the iOS 9.2.1 firmware file for your device from this page

Step 2: Make sure you have the latest version of iTunes installed on your computer. On Windows, this can be done by going to the menu "Help" -> "Updates", on OS X, looking for new versions on the updates tab in the Mac App Store.

Step 3: Back up your iPhone, iPad, or iPod touch to iTunes or iCloud

Step 4. Go to the menu " Settings» -> « iCloud” and turn off the “ Find iPhone»

After the installation is completed, the system's offers to install iOS 9.3 must be rejected.
