How to roll back from ios 9 to 8. How to roll back the version of IOS on iPhone, iPad

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

When to rollback iOS

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

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available to users in a too raw form, with errors in the code and flaws, or the device that was updated has become outdated for the loads created by the new version of IOS.

Please note that rollback of any device for any version is not possible, detailed information about which device can be rolled back to which version of the firmware can be viewed on the following website - 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.
The version of the software of your choice in an IPSW format downloaded to an easily accessible folder. 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.
A 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

Please note 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 firmware of the device, 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.

Connect your device to your computer using a USB adapter.
Log in to the system.
Go to the settings of your device by clicking on the icon in the form of a phone or tablet.
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.
A window with folders will open, you need to specify the path to the firmware that you downloaded earlier.
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 by 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 point 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 any elements will remain from the previous version is 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.

After downloading and opening the program, select the Extras section.
Click on the Even More button.
In the menu that opens, go to the Restore block.
Click the IPSW button to specify the path to the pre-downloaded firmware.
In the notification that appears, you will be asked whether to cancel the promotion of the modem or not. Click on the "Yes" option.
A window will open in which you will be warned that now the device will need to be put into recovery mode, close it.
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.
If you have not performed similar rollback operations with this program before, then click on the Remote button so that it automatically finds the necessary hashes on its servers.
Done, now it remains to wait for the process to end. 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 it is not worth it, since there is a better option - to use the special App Admin program. You can download it directly from the App Store for free. Thanks to this application, you can view all the available versions of the 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 drop the selected application.

So, installing 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.

Each Android and iOS update has its own benefits. However, it sometimes happens that a fresh version of the system has some critical flaws that are not corrected for a long time by the developer. Or, a situation may arise when a new update just terribly loads the mobile device and slows down. One of these unsuccessful updates was iOS 9.3.5. And everything would be fine, a new version was released that would correct the existing shortcomings, but this update was the last for a number of devices based on the A5 processor, and more specifically:

iPad 2.

iPad 3 (iPad with Retina display).

iPad mini (1st generation).

iPhone 4s.

iPod touch 5.

First of all, we need to use an exploit that will allow us to get a jailbreak. The list of devices on which it turns out to be used is as follows:

iPhone 4s.

iPhone 5.

iPhone 5c.

iPad 2.

iPad 3.

iPad 4.

iPad mini 1.

How to Jailbreak

1. Download

2. Download

3. We connect the iPhone or iPad to the computer using a cable.
4. Launch Cydia Impactor and drag the ipa file into the program window.

5. When prompted, enters your Apple ID information in the pop-up window.

6. Go to "Settings" -\u003e "General" -\u003e "Device Management" on the mobile device, select the Phoenix certificate and press the "Trust" button twice.

7. Return to the home screen and launch the Phoenix application. We agree to the offer to receive push notifications. Uncheck Phoenix at the bottom and click on the circle.

8. Lock the screen of your mobile device and after a few seconds you will see a message about the successful hacking of the system.

9. Unlock your smartphone or tablet and open Phoenix again. You will see an animation showing the preparation for installing Cydia. Wait for the device to restart, after which the Cydia app store will be installed.

10. It is worth clarifying that after each reboot you will have to repeat steps 7-9.

How to downgrade to iOS 8.4.1?

Open the Cydia store and search for "Filza File Manager".

We launch this file manager.
Go to / System / Library / CoreServices

We are looking for the SystemVersion.plist file

Editing Version (9.3.5) and Build (13G36) to Version (6.1.3) and Build (10B329) respectively.

We save and reboot the device (simultaneously hold down the power button together with the Home key and hold it until the loading screen with an apple appears).

We go into the settings and check the system version. If we see the values \u200b\u200bthat we assigned, then everything went well.

Go to the "Software Update" section and download the update to iOS 8.4.1

After the update, you need to do a full reset through the "Erase all content and settings"

Attention! In this article, I use screenshots from the iPod Touch, but this does not play a significant role. This manual is valid equally for iPad, iPhone or iPod Touch.

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

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 in the lineup. 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 valid. For example, the whole world is currently testing the iOS 9 Public Beta. The official version of iOS 9 will be released in the fall. So, up to this point, the user has the opportunity to flash his device to the official iOS 8.4.

b) if the new official firmware has just been released. 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 make a rollback. 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. Download the firmware from your device, which you can roll back to.

Step 2. Disable the function: “Find iPad, iPhone or iPod” (depending on your device). Settings-\u003e iCloud.

If this is not done, then iTunes will not let you 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 held down 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 re-configure it (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. This is also why it is recommended that you save a backup to your computer before flashing iOS.

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

It is possible to roll back to a previous version of the operating system. Apple traditionally leaves such an opportunity for a short time after the release of each new OS. A day after the update was released, the company is still issuing certificates for iOS 8.4.1.

Released September 16, iOS 9 is a major software release since. Nevertheless, many iPhone and iPad owners report problems with their devices. Failures began at the stage of downloading the update, when people due to the unavailability of Apple services.

Owners of iOS devices complain about the incorrect operation of Wi-Fi, missing menu items in the settings, graphic artifacts when displaying the interface, and freezing of the operating system. Among the innovations in iOS 9 are improved power consumption algorithms, but in reality the battery of gadgets loses its charge too intensively.

Probably, subsequent updates of iOS 9 will fix these problems, but until then it makes sense to perform the downgrade procedure - rollback to iOS 8. This is only about iOS 8.4.1 - Apple still issues digital signatures for it. It is worth remembering that the situation can change at any time.

Step 4: Disable Touch ID / Password in the main settings section.

Step 5: Turn off Find My iPhone in Settings -\u003e iCloud.
