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

Did you not hesitate to take the opportunity to update your iPhone and iPad to iOS 10, but later found out that the firmware is causing problems that you no longer want to endure?

You are not alone - many users are experiencing problems with fast battery drain or performance drops. If you are one of those users who are wondering how to return an old version of iOS, then you should know the whole truth about the situation with a rollback to previous versions.

Just a month after the release of iOS 10, Apple stopped signing iOS 9.3.5, which means it's impossible to rollback from new versions. The same thing happened with versions 10.1 and 10.2. According to Apple, all bugs that previously prevented users from fully enjoying iOS 10 have been eliminated and there is no need to go back to older versions that could threaten the security of user data.

Until the end of 2016, users could use the standard method - downloading the IPSW file of the previous iOS version using iTunes. But now Apple has covered up this opportunity and users who hastened to try new opportunities have no 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 the SHSH blobs were saved, it was possible to rollback to older versions of iOS. But right before the New Year, Apple blocked the utility by adjusting the work of the servers for issuing digital signatures. After that, everyone who tried to extract digital certificates only received an error from the server.

By February 2017, the author of the utility managed to find a solution to bypass the blocking 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 beforehand. For example, using Prometheus, you can save SHSH blobs for iOS 10.2, upgrade to 10.2.1, and then go back to the previous version.

As for the rollback from iOS 10.X.X to iOS 9.X.X, Apple has put a fat point by closing any possibility of downgrading to the old version. When trying to install an old version of iOS, iTunes contacts the certificate issuing server in order to activate the firmware. Since Apple considers firmware below 10.2 to be irrelevant, the user simply gets an error 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 being released do not contain errors.
If in the future there are any new ways to downgrade to old versions, we will definitely inform you about it.

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 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 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 it 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 firmware from 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 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 for the procedure to complete, 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).

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 - 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 firmware (in general, all versions for all versions of the iPhone!) Can be found on this page.


Now let's take a look at how to uninstall iOS 9 and return iOS 8:

  1. download the latest iOS 8 firmware for your device;
  2. turn off your iPhone or iPad;
  3. connect your smartphone or tablet to your computer;
  4. start iTunes;
  5. hold and hold the Home and Off buttons at the same time - this is necessary to enter DFU mode;
  6. after 10 seconds, release the power button, and continue to hold the Home button until the device is recognized in recovery mode in iTunes;
  7. after recognition, press and hold the key (in OS X) on the keyboard;
  8. click the Restore iPhone / iPad button;
  9. select the downloaded firmware file in the window that appears;
  10. click the Restore button again to confirm the operation;
  11. 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 release of the final version of iOS 9? It will become of her!

How to downgrade iOS 9 to iOS 8.4.1?

By the company Apple The updated OS was presented on September 16. There were certain delays in updating the operating system, but after 2-3 days the number of those wishing to update the OS will decline and everything can be done much faster. There are already the first people who want to roll back the system after updating to the previously installed iOS 8.4.1. Let's talk about how this can be done.

There are no significant reasons for such operations: the updated OS runs smoothly, the San Francisco font looks amazingly beautiful, and "notes" in which you can draw have been the dream of many for many years. If the desire to roll back still remains, a certain determination will be required. For these manipulations, Apple took a very short time, during which you need to have time to roll back the system.

Requires a Lightning cable to rollback or downgrade for iPad 2/3/4 or iPhone 4s. ITunes must be enabled on the computer, download IPSW file (source of the old operating system), which can be downloaded by following the link: http://osxdaily.com/2015/08/13/ios-8-4-1-update-ipsw-download, you will need to select the version of the mobile device. Next, you must follow the instructions:

  1. On a mobile device, you need to go to: Settings-iCloud menu and further, disable the "Find my iPhone" option.
  2. You will need to turn off your mobile device, for this you need to hold the lock button for a long time. Then launch iTunes on your personal computer.
  3. We connect the iOS mobile device via a cable to the computer, while you need to immediately hold down the "home" and lock buttons at the same time. You need to hold for at least 10 seconds. Further, the lock button must be released, and the "home" button must continue to be held. You need to keep it until a warning window appears in iTunes that the iOS device has appeared in Recovery Mode.
  4. In iTunes, you need to select the model of your gadget and click on the "Restore iPhone" button, while holding down the Shift button on Windows or the OPTION button on Mac.
  5. You need to select the IPSW file that was downloaded earlier.
  6. Wait for the process to complete, then the device should start. Done.

Is the decision to stay on iOS 8.4.1 justified? The updated OS works great, there are no visible glitches, problems, lags yet. The only reason to justify the old version of the operating system is applications. Protracted adaptation of applications to the new OS is possible. In general, you should not rush to the transition to iOS 9.
