It is possible to rollback to a previous version of the operating system for which jailbreak tools are available. Apple traditionally leaves this option for a short time after the release of a new OS. A day after the update was released, the company still issues certificates for iOS 8.4.
Released on August 13, iOS 8.4.1 is a technical update aimed at fixing bugs from the previous version. The problem is that in addition to fixing Apple Music crashes, this release also fixes vulnerabilities that are necessary for the TaiG jailbreak utility to work. Anyone hoping 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 the downgrade procedure - rollback to the previous stable version of the OS. We are talking only about iOS 8.4 - for which Apple issues digital signatures. It is worth remembering that the situation can change at any moment.
Requirements:
- iPhone or iPad with iOS 8.4.1 operating system.
- IOS 8.4 IPSW file.
- iTunes 12 for Mac or Windows.
How to downgrade iOS 8.4.1 to iOS 8.4:
Step 1: Download the iOS 8.4 firmware file in IPSW format from this link.
Step 2: 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. You can do this by going to settings in iCloud -\u003e Backup -\u003e 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: Disable Find My iPhone in Settings -\u003e iCloud.
Step 6: Connect your iPhone or iPad with 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) 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 until the procedure is completed, the OS recovery process will take from 5 to 10 minutes. You can now 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).

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 by the developer for a long time. 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 all 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.

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 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:
- 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 by the new IOS version.
Please note that it is not possible to rollback any device for any version, you can see detailed information on which device to which firmware version can be rolled back 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 turn off 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 or 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 the 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 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 RedSnow program. 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 the 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 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 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 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 an 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.
It has not even come out yet, but is available only to a few developers, but people are already complaining about the glitches of the new operating system. And some even want to install iOS 8 instead of iOS 9, or even an earlier version. How is it that developers have access and do they really need instructions on how to rollback iOS 9? Okay, okay, admit that you're not a developer and read this guide on how to return iOS 8 further.
Actually, removing iOS 9 is quite simple - everything is done through iTunes. The main thing is to download the correct firmware for your iPhone or iPad. To make it easier to find, here's a list of the latest final firmwares for current iPhones (4S to 6/6 Plus):
And so a complete list of older firmwares (in general, all versions for all iPhone variants!) Can be found on this page.
Now let's take a look at how to uninstall iOS 9 and return iOS 8:
- download the latest iOS 8 firmware for your device;
- turn off your iPhone or iPad;
- connect your smartphone or tablet to your computer;
- start iTunes;
- hold and hold the Home and Off buttons at the same time - this is necessary to enter DFU mode;
- after 10 seconds, release the power button, and continue to hold the Home button until the device is recognized in recovery mode in iTunes;
- after recognition, press and hold the key (in OS X) on the keyboard;
- click the Restore iPhone / iPad button;
- select the downloaded firmware file in the window that appears;
- click the Restore button again to confirm the operation;
- wait for the operation to complete.
Yes, that's all. The idea is fast and not difficult. By the way, I would recommend that you keep the latest version of the firmware with your current operating system - you never know Apple will make it unavailable after the final version of iOS 9 is released? It will become of her!
