It is possible to rollback to a previous version operating system. Apple has traditionally left this opportunity for a while after the release of each new OS. A day after the release of the update, the company is still issuing certificates for iOS 8.4.1.
Released on September 16, the iOS 9 update is a major software release with a long list of changes and improvements. However, many iPhone and iPad owners report problems with their devices. Failures began at the stage of downloading the update, when people could not get the promised distribution due to the unavailability of Apple services.
Owners of iOS devices complain about Wi-Fi not working correctly, missing menu items in the settings, graphical 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 gadget battery loses charge too intensively.
Probably, subsequent iOS 9 updates will fix these problems, but until then it makes sense to perform the downgrade procedure - rollback to iOS 8 firmware. This is only about iOS 8.4.1 version - Apple still issues digital signatures for it. It is worth remembering that the situation can change at any time.
Requirements:
- iPhone or iPad running iOS 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 A: Check that you have the latest version of iTunes installed. You can download iTunes 12.3.
Step 3: Make a backup of the data on the device. You can do this by going to Settings in iCloud -> Backup–> Create a backup, 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 down Shift (or Alt on OS X) on your keyboard 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. Now you can use your device with iOS 8.4.1.
Have you taken the opportunity to update your iPhone and iPad to iOS 10 without hesitation, only to find out later that the firmware is causing problems that you no longer want to endure?
You are not alone - many users have found problems with fast battery drain or performance drops. If you are one of those users who are wondering how to go back to the old version of iOS, then you should know the whole truth about the situation with the rollback to previous versions.
Just a month after the release of iOS 10, Apple stopped signing iOS 9.3.5, which means that newer versions cannot be rolled back. The same thing happened with versions 10.1 and 10.2. According to Apple, all the bugs that previously prevented users from fully enjoying iOS 10 have been fixed and there is no need to revert to older versions that could threaten the security of users' data.
Until the end of 2016, users could use the standard method - downloading the IPSW file of a previous version of iOS using iTunes. But now Apple has closed this opportunity and users who hastened to try new features have no other choice but to look for unconventional methods to solve the problem.
In December 2016, a hacker using the nickname tihmstar released the Prometheus utility, with which, provided that SHSH blobs digital certificates were saved, it was possible to roll back to older versions of iOS. But right before the New Year, Apple blocked the utility by adjusting the work of digital signature issuing servers. After that, everyone who tried to extract digital certificates received only an error from the server.
By February 2017, the author of the utility managed to find a solution to bypass the lock, and some users were able to use the utility to downgrade (downgrade or rollback). But the tool only worked inside 10.0.x - 10.2.1 if SHSH blobs were saved in advance. For example, with Prometheus you can save SHSH blobs certificates for iOS 10.2, upgrade to 10.2.1, and then revert back to the previous version.
As for the rollback from iOS 10.X.X to iOS 9.X.X, Apple has put an end to it by closing any possibility of switching to the old version. When trying to install an older version of iOS, iTunes contacts the certificate issuing server in order to activate the firmware. Since Apple considers firmware below 10.2 to be out of date, the user simply gets an error that occurs due to the lack of digital signatures.
Thus, iOS users are left to look for the advantages of existing firmware versions and update only when they are sure that the new versions released contain no errors.
If there are any new ways to downgrade to older versions in the future, we will definitely let you know.
It is possible to roll back to a previous version of the operating system for which jailbreak tools are available. Apple has traditionally left this possibility for a short time after the release of the new OS. A day after the release of the update, the company is still issuing certificates for iOS 8.4.
Released on August 13, iOS 8.4.1 is a technical update that fixes bugs in the previous version. The problem is that in addition to fixing Apple Music crashes, this release fixes vulnerabilities that are necessary for the TaiG jailbreak utility to work. Anyone who expects to use Cydia in the future should install iOS 8.4 as soon as possible.
Right now, iPhone and iPad owners with iOS 8.4.1 have the opportunity to perform a downgrade procedure - a rollback to the previous stable version of the OS. We are talking only about iOS 8.4 - for her, Apple issues digital signatures. It is worth remembering that the situation can change at any moment.
Requirements:
- iPhone or iPad running iOS 8.4.1.
- iOS 8.4 IPSW file.
- iTunes 12 for Mac or Windows.
How to downgrade from iOS 8.4.1 to iOS 8.4:
Step 1: Download iOS 8.4 firmware file in IPSW format from this link .
Step 2 A: Make sure you are using the latest version of iTunes. You can download iTunes 12.2.2 on this page.
Step 3: Back up the information on the device. This can be done by going to settings in iCloud –> Backup –> Create a backup, or by connecting your iPhone or iPad to your computer and saving a 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 your iPhone or iPad running iOS 8.4.1 to your computer.
Step 7: Launch iTunes and select the icon of your gadget in the top bar of the program.
Step 8: Hold down Shift (or Alt on OS X) on your keyboard and click the Restore button.
Step 9: In the program window, specify the iOS 8.4 firmware file for your iPhone or iPad.
Step 10: Wait for the procedure to complete, the OS recovery process will take 5 to 10 minutes. Now you can use your device with iOS 8.4.
Now, after switching to iOS 8.4, you can jailbreak according to the instructions (for Windows) or (for Mac).
With update software on mobile devices Today almost everyone is familiar with it. This operation usually does not provide for anything difficult. The owners of "apple" phones were offered new iOS 10 version. However, this software did not impress users too much. Therefore, many are thinking about how to roll back iOS 10 to 9. What should every owner of an "apple" phone or tablet know about this operation? What scenarios are possible?
Myth or reality?
To begin with, it remains to be seen whether it is possible to roll back iOS 10 to version 9 of the software. After all, often after updating one or another content on mobile phone you cannot rollback to older versions.
Fortunately, iOS rollback on iPhone/iPad is possible. This is an operation available to all. It is recognized as official, does not require any special knowledge and skills. However, there are a few things you need to know before you rollback.
Before reset
How to rollback iOS 10 to 9? Before bringing your idea to life, you need to remember the following:
- Backups from the tenth version of the operating system are not suitable for iOS 9.
- There are several types of rollback - a "clean" version and with saving data. The second method is not recommended. It causes problems when using the Music app.
- Before performing the operation, you need to make sure that sync is enabled in iCloud. In the corresponding settings item in the "Settings" -iCloud menu, you must enable the corresponding switch. The "Library" slider also needs to be activated.
- Disable Find My iPhone. If you neglect this step, rollback will be impossible.
Perhaps this is enough. You can think about how to roll back iOS 10 to 9.
Full rollback
Let's start with the most preferred approach. This is a "clean" rollback. This method is used most often in practice. It allows you to avoid system failures and malfunctions.
How to rollback iOS10 to 9? To do this, you must follow certain instructions. It looks something like this:
- Launch iTunes on PC.
- Connect iPhone to computer. To do this, you need to use a USB cable.
- Launch iTunes. In the "Browse" menu, select the "Make a backup copy" option. Wait for the operation to complete.
- Go to ipsw.me. Select your phone model here along with the firmware.
- Wait until the appropriate software is downloaded. After the operation is completed, go to iTunes and in the "Overview" tab, click on Option (in Windows, this is the Shift button).
- Click on "Restore iPhone".
- Select the previously downloaded iOS in the window that appears.
- Complete the update by clicking on "Restore".
That's all. Now you can wait for the device to reboot. During the initialization of the OS, you can not disconnect the device from the PC. In the end, you need to select "New iPhone" and go through authorization using AppleID.
Saving settings
From now on, it’s clear how to roll back iOS 10 to 9. The instruction presented to your attention earlier implies full reset settings and data. You can save them if you wish. What will be required for this?
How to roll back iOS 10 to 9 while keeping the information on the device? We will have to adhere to the previously proposed algorithm, but with some changes. While selecting the firmware, you will need to press "Shift", and then select "Update". The rest of the algorithm of actions will be exactly the same. When updating, you must unlock the gadget to successfully complete the operation.
So, now it's clear how you can roll back the operating system for "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 to use exactly? As already mentioned, it is recommended to pay attention to the "clean" rollback. Only in this way can we confidently talk about normal work with iOS in the future.
Attention! In this article, I use screenshots from the iPod Touch, but this does not play a significant role. This manual is equally relevant for iPad, iPhone or iPod Touch.
iOS Firmware Rollback (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 ( 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. All of these devices can be rolled back exclusively on iOS 8.4(as of July 12, 2015) even with saved SHSH.
Now 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, at the moment the whole world is testing 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 current officially iOS 8.4.
b) if new official firmware just got 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 their mind and roll back. At some point, Apple suddenly stops signing old firmware, and then a rollback is impossible or much more difficult.
The rollback instruction in this case is identical to the firmware through recovery ..
Step 1. Download the firmware from your device, to which you can rollback.
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 through the cord. We go to iTunes and select the device. We are looking for the “Restore” button and press it 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 restore / rollback process begins.
This must be remembered!
The device will be reset to factory settings. That is, before starting the system, you will have to reconfigure it (you must at least know the password for the Wi-Fi network).
You can only roll a backup to an older firmware if you still have a backup made on the old firmware. This is also why it is recommended before iOS firmware save a backup to your computer.
Good luck everyone! :) If you have any questions, additions or problems - write comments.
