How to roll back the version of iOS 9 to 8. How to roll back the version of iOS on iPhone, iPad. Video tutorial: How to downgrade iOS version

After updating to a new version of iOS, you may notice that you do not like the firmware. In this case, there is an excellent solution - roll back the software to the optimal version, in your opinion. That is, if you updated to, for example, IOS 10, then you can easily install it on your iOS device 8 using the instructions below.

When is it necessary to rollback iOS?

Reasons to install an older version operating system The following circumstances may occur:

With new firmware versions, the design changes, and not all users may like the new design.
The most common reason is the appearance of freezes and glitches. Happen similar problems for two reasons: either the new version of the firmware became available to users in a too crude form, with errors in the code and shortcomings, or the device that was updated was already outdated for the loads created by new version IOS.

Please note that it is not possible to roll back any device to any version; you can view detailed information about which device to which firmware version can be rolled back to on the following website - http://appstudio.org/shsh. All data is located in table format.

How to roll back iOS to a specific version on an Apple device

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

iTunes installed on your computer and updated to the latest version.
Your chosen version downloaded to an easily accessible folder software, having the IPSW format. You can download it from trusted websites that distribute IOS firmware for free, for example, using the following link - http://appstudio.org/ios. Download the firmware strictly for your device model, otherwise problems will arise during installation.
A USB adapter that will connect your device to your computer.

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

Saving important data

Please note that when you roll back your device, all data, applications and media files from it are permanently erased, 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 later in the article, but it is no less stable. You can save everything you need using a backup copy created as follows:

Disable password

Another important point is to disable the password and Touch ID, if it is 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, since, otherwise, iTunes simply will not allow you to perform any actions:

Firmware rollback

If all previous preparatory work has been carried out, then you can begin the rollback itself. It doesn't matter which device you're downgrading from, or from which version of iOS you're downgrading to.

Connect the device to the computer using a USB adapter.
Log in to the system.
Go to your device's settings by clicking on the icon that looks like a phone or tablet.
Hold down the Shift button on your keyboard if you're using Windows, or the Option button 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 while iTunes extracts the software from the firmware and installs it. The process can last from five minutes to half an hour, do not disconnect the device from the computer or interrupt the process with any actions, otherwise the device may enter endless recovery mode.

Rollback without data loss

This rollback option also exists; it allows you to rollback without losing the data on the device. To do this, in point 4 of the “Rolling Back Firmware” section, you need to click on the “Restore” button and the “Update” button. All other steps are completely 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 iTunes method 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 official website of the developer - 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 previously downloaded firmware.
The notification that appears will ask you whether to cancel the modem upgrade or not. Click on the “Yes” option.
A window will open in which you will be warned that the device will now need to be put into recovery mode, close it.
Connect the device to the computer using 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 previously performed such rollback operations with this program, then click on the Remote button so that it will automatically find the necessary hashes on its servers.
Done, now all you have to do is wait for the process to complete. 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 roll back 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 - use special program App Admin. You can download it directly from App Store for 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, just select the applications to roll back and enter the unique version number to which you want to roll back the selected application.

So, installing an older version of software is possible on all Apple devices, but you can not roll back to any version, but only to those that have the SHSH signature. The process can be completed either through the official iTunes application or 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.

On iPhone and iPad, many users had a desire to roll back to the previous, faster and more stable firmware.

So, now it’s clear how you can roll back the operating system of Apple phones and tablets from version 10 to version 9. No more options for the development of events are provided. You can't rollback without iTunes.

Which method should I use? As already mentioned, it is recommended to pay attention to the “clean” rollback. This is the only way to speak with confidence about normal operation with iOS in the future.

Attention! In this article I use screenshots from iPod touch, but this does not play a significant role. These instructions are equally relevant for iPad, iPhone or iPod Touch.

Rollback iOS firmware (Downgrade iOS)– installation of 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 (a 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 line. Rollback is possible for all these devices exclusively on iOS 8.4(as of July 12, 2015) even with saved SHSH.

Now the general case. As a rule, a rollback of more old version firmware is possible:

a) if the previous firmware is still considered current. For example, in this moment the whole world is testing iOS 9 Public Beta. Official version iOS 9 will be released in the fall. This means that until this moment the user has the opportunity to flash his device to the officially current 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 a 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->iCloud.

If you do not do this, then iTunes will not allow you to update the firmware. After flashing, do not forget to enable the option back.

Step 2. We connect the device to the computer via a cable. Go to iTunes and select the device. We look for the “Restore” button and press while holding down the Alt-Option key (in OS X) or Shift (in Windows).

In a new window, select the downloaded firmware. Then in the window that appears, click “Restore” and the recovery/rollback process begins.

This must be remembered!

The device will be restored 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).

You can roll a backup copy onto an older firmware only if you still have a backup copy made specifically on old firmware. This is also why it is recommended to save a backup copy to your computer before updating iOS.

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

It is possible to roll back to previous version operating system. Apple traditionally leaves this option 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 update 9 is a major software release with a large list of changes and improvements. However, many iPhone and iPad owners report problems with their devices. The failures began at the stage of downloading the update, when people could not receive the promised distribution due to the unavailability of Apple services.

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

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

Requirements:

iPhone or iPad iOS control 9.0.
iOS 8.4.1 firmware file in IPSW format.
iTunes 12.3 for Mac or Windows.

How to downgrade from iOS 9.0 to iOS 8.4.1:

Step 1: Download iOS 8.4.1 IPSW file from this link.

Step 2: Check that you have the latest installed iTunes version. You can download iTunes 12.3.

Step 3: Make a backup of the data on the device. This can be done by going to settings in iCloud -> Backup–> Create a backup copy, or by connecting your iPhone or iPad to your computer and saving the backup using iTunes.

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

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

Step 6: Connect to iPhone computer or iPad with iOS 9.0 on board to your computer.

Step 7: Open iTunes and select the icon of your gadget in the top bar of the program.

Step 8: Hold Shift on your keyboard (or Alt on OS X) and click the “Restore” button.

Step 9: In the program window, specify the iOS 8.4.1 firmware file downloaded in step 1.

Step 10: Wait for the procedure to complete, the OS recovery process will take some time. You can now use your device with iOS 8.4.1.
