Ready!

When you upgrade to a newer version of IOS, you may notice that you don't like the firmware. In this case, there is a great way out - to roll back the software to the optimal version, in your opinion. That is, if you have updated to, for example, IOS 10, then you can safely install on your IOS device 8 using the instructions below.

When to rollback iOS

The reasons for installing an older version of the operating system may be the following circumstances:

• Design changes with new firmware versions, and not all users may like the new design.
• The most common reason is the appearance of freezes and glitches. There are similar problems for two reasons: either the new firmware version became available to users in a too raw form, with errors in the code and flaws, or the device that was updated has become outdated for the loads created new version IOS.

Please note that it is not possible to rollback any device for any version, detailed information about which device can be rolled back to which version of the firmware, you can see on the following site - http://appstudio.org/shsh. All data is arranged in a table format.

How to rollback iOS to a specific version on an Apple device

Before starting the process, you need to prepare the following things:

• ITunes installed on your computer and updated to the latest version.
• Downloaded to an easily accessible folder the version of your choice software in the IPSW format. You can download it from trusted Internet sites that distribute IOS firmware for free, for example, at the following link - http://appstudio.org/ios. Download the firmware strictly for your device model, otherwise there will be problems during installation.
• USB adapter that connects your device to your computer.

If you have met all of the above conditions, then the next step will be to prepare the device itself for the rollback process.

Saving important data

Keep in mind that when you roll back a device, all data, apps, and media files are permanently erased from the device, so it's worth taking care of them. There is an option that allows you to delete files from the device, it will be discussed below in the article, but it is no less stable. You can save everything you need using a backup, created as follows:

Disable password

Another important point is disabling the password and Touch ID, if supported and enabled on your device.

Deactivating Find My iPhone

Before any actions with the device's firmware, you must disable the "Find iPhone" function, otherwise, iTunes will simply not allow you to perform any actions:

Rollback firmware

If all the previous preparatory work has been carried out, then you can proceed to the rollback itself. It does not matter from which device you rollback, as well as from which and to which version of IOS you will be migrated.

1. Connect your device to your computer using a USB adapter.
2. Log in to the system.
3. Go to the settings of your device by clicking on the icon in the form of a phone or tablet.
4. Hold down the Shift key on your keyboard if you're using Windows, or the Option key if you're using Mac OS. Without releasing the key, click on the "Restore" button.
5. A window with folders will open, you need to specify the path to the firmware that you downloaded earlier.
6. Wait for iTunes to extract the software from the firmware and install it. The process can last from five minutes to half an hour, do not disconnect the device from the computer and do not interrupt the process with any action, otherwise the device may enter the infinite recovery mode.

Rollback without data loss

This rollback option also exists, it allows you to rollback without losing data on the device. To do this, in paragraph 4 of the "Firmware Rollback" section, you need to click on the "Restore" button, and the "Update" button. All other steps are exactly the same. The only thing worth considering is that performing a full recovery, that is, resetting the system and installing it from scratch, is safer, since the chance that from previous version any elements will remain much lower.

Third party rollback programs

If for some reason the method with iTunes does not suit you, then you can use the third-party program RedSnow. It is distributed free of charge for both Windows and Mac OS on the developer's official website - http://redsnow.ru.

1. After downloading and opening the program, select the Extras section.
2. Click on the Even More button.
3. In the menu that opens, go to the Restore block.
4. Click the IPSW button to specify the path to the pre-downloaded firmware.
5. In the notification that appears, you will be asked whether to cancel the promotion of the modem or not. Click on the "Yes" option.
6. A window will open in which you will be warned that now the device will need to be put into recovery mode, close it.
7. Connect your device to your computer with a USB adapter and enter it into DFU Mode. How to do this is described step by step in the program itself.
8. If you have not performed such rollback operations with this program before, then click on the Remote button so that it automatically finds the necessary hashes on its servers.
9. Done, now it remains to wait for the end of the process. The device will automatically update to the version you downloaded and turn on, after which you will have to go through the initial setup process.

Is it possible to rollback individual applications

If the purpose of your system rollback is to install older versions of applications, then you should not carry it out, since there is a better option - to use special program App Admin. You can download it directly from App Store is free. Thanks to this application, you can view all available versions of applications installed on your phone and roll back to them. To use the program, you just need to select the applications to rollback and enter a unique version number to which you want to roll back the selected application.

So, the installation of an older version of the software is possible on all devices from Apple, but you can rollback not to any version, but only to those that have the SHSH signature. The process can be performed both through the official iTunes application and through third party programs... The main thing is to download the correct firmware version and not interrupt the update process until it is fully completed.

Attention! In the article, I use screenshots with iPod Touch, but this does not play a significant role. This instruction equally relevant for iPad, iPhone or iPod Touch.

Rollback iOS firmware (Downgrade iOS)- installing an older firmware version. Previously, downgrading firmware to old systems was difficult, but more likely. To do this, the user had to save SHSH-certificates (digital signature, unique for each device).

V in this case we are rolling back iOS 9 to iOS 8. These two systems support: iPad 2, iPad Mini 1, iPhone 4s, iPod Touch 5G and newer devices. Rollback is possible for all these devices. exclusively on iOS 8.4(as of July 12, 2015) even with SHSH saved.

Now for the general case. As a rule, a rollback to an older firmware version is possible:

a) if the previous firmware is still considered up-to-date. For example, in this moment the whole world is testing iOS 9 Public Beta. Official version iOS 9 will be released in the fall. So, up to this point, the user has the opportunity to flash his device to the current officially iOS 8.4.

b) if new official firmware just came out. For example, after the official release of iOS 9, the user will have from 1 to 7 days (maybe a little more) to change his mind and roll back. At some point, Apple suddenly stops signing old firmware and then rollback is impossible or significantly difficult.

The rollback instructions in this case are identical to the firmware via recovery ..

Step 1. We download the firmware from our device, which can be rolled back.

Step 2. Disable the function: “Find iPad, iPhone or iPod” (depending on your device). Settings-> iCloud.

If this is not done, then iTunes will not allow you to carry out the firmware. After flashing, do not forget to turn the option back on.

Step 2. We connect the device to the computer via a cord. We go into iTunes and select the device. We are looking for the "Restore" button and press with the previously pressed Alt-Option (in OS X) or Shift (in Windows) key.

In the new window, select the downloaded firmware. Then in the window that appears, click "Restore" and the restore / rollback process begins.

This must be remembered!

The device will roll back to factory settings. That is, before starting the system, you will have to configure it again (you must at least know the password for the Wi-Fi network).

A backup copy can be rolled onto an older firmware only if you have a backup copy made on the old firmware. Including therefore, it is recommended to save the backup on computer.

Happy rollback everyone! :) If you have any questions, additions or problems - write comments.
