After updating to a new version of IOS, you may notice that you do not like the firmware. In this case, there is a great way out - to roll back the software to the optimal, in your opinion, version. That is, if you have upgraded to, for example, IOS 10, then you can safely install it on your IOS device 8 using the instructions below.
Reasons to install more old version operating system may be the following circumstances:
Please note that it is not possible to roll back any device for any version, you can view detailed information about which device to which firmware version can be rolled back to the following site - http://appstudio.org/shsh . All data is arranged in a table format.
Before starting the process, you need to prepare the following things:
If all of the above conditions are met by you, then the next step is to prepare the device itself for the rollback process.
Please note that when you roll back a device, all data, applications, and media files are permanently erased from it, so you should take 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 created as follows:
Another important point is to disable the password and Touch ID, if it is supported and enabled on your device.
Before any actions with the firmware of the device, you must turn off the Find My iPhone function, because, otherwise, iTunes simply will not allow you to perform any actions:
If all the previous preparatory work has been carried out, then you can proceed to the rollback itself. It doesn't matter which device you're downgrading from, or which version of IOS you'll be migrating from and to.
This rollback option also exists, it allows you to rollback without losing 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 to keep in mind 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.
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 official website of the developer - http://redsnow.ru.
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. With this application, you can view all available versions applications installed on your phone and roll back to them. To use the program, just select the applications to roll back and enter a unique version number to which you want to roll back the selected application.
So, installing an older version of software is possible on all devices from Apple, but you can not roll back to any version, but only to those that have an SHSH signature. The process can be performed both through the official iTunes app, 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 is possible to roll back to 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 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. 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 incorrect Wi-Fi operation, missing menu items in the settings, graphical 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 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:
Step 1: Download IPSW- iOS file 8.4.1 at 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 backup, or by connecting your iPhone or iPad to your computer and saving a backup from 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 get back the old iOS version, 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 company stopped signing the iOS 9.3.5 version, which means it is impossible to rollback from new versions. 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 in a standard way– by 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 issuance servers digital signatures. 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 certificates blobs 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 pros existing versions firmware 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.
Don't like iOS 11? Why was it updated then? … Although, this release is really special. Not everyone will go right away. Every year, Apple introduces new versions of iOS with supposedly improved features and improved optimization, but in fact, for the last couple of years, we have been “rubbed some kind of game” full of bugs and shortcomings.
We, in turn, find ourselves in the place of “guinea pigs”, who must identify weaknesses and point them out to Apple for further correction. What was the recent release of the nightmarish iOS 9 worth when users around the world began to complain that their .
In principle, a similar situation was with the release of iOS 8 ... and 7 too. So, if something strange happens to your iPhone after the update, maybe it's not too late to rollback to a previous version of iOS. Today I will tell you how to do it.
But first, I would like to mention a couple of nuances related to iOS firmware and which you simply must know. As you already know, update on more new firmware goes quite intuitively by clicking on a single button in the Settings of the phone or in iTunes on the computer.
If you want to return to a non-previous version of iOS, you must first download the firmware file with the ipsw extension from the Internet yourself, and then install it by connecting your phone to a computer.
If you suddenly decide that you can now install any old firmware, I will have to upset you. See how the situation is. During the installation of any version of iOS, your device contacts the Apple server for a digital signature.
If the server sees a version of iOS on your device that is no longer supported, it will not sign it and the installation will fail. If you don’t understand, I’ll explain with an example: if you just installed iOS 9.0, then now you can only return to 8.4.1 and that’s not a fact. With the release of new versions iOS Apple stops signing older versions.
Maximum “you can take one step back”. At the time of this writing, the only current firmware for all devices since the iPhone 4S is 9.0.2.
How to find out what versions of iOS are relevant today? Very simple! We go to ipsw.me and click on the model of your device.
The step by step guide looks like this:
STEP 1 - Download the firmware file with the extension .ipsw from the link above:
STEP 2 - Make sure you have the latest version of iTunes
STEP 3 - If possible,
STEP 4 - B Settings iPhone turn off features: Find iPhone And Touch ID/Password
STEP 5 - Connect your iPhone to your computer using USB cable and launch iTunes
STEP 6 - Click on your device icon in the upper left corner of the window
STEP 7 - Hold down the Shift key ( Option/Alt on MAC), click the Refresh button in the iTunes window
On iPhone and iPad, it is possible to rollback to a previous version of the OS. Traditionally, after the release of each new edition of the branded “axis”, Apple leaves this opportunity for a while. A day after the release of the cumulative update, the company is still issuing certificates for iOS 9.2.1.
Released on March 21, iOS 9.3 is a major software release with a large list of changes. The main innovation is support for the Night Shift mode, which automatically shifts the color temperature of the display to the warm end of the spectrum at night. Studies have shown that bright blue color in the evening can affect a person's circadian rhythms, making it harder to fall asleep. Other innovations include password-protected Notes, an improved version Apple apps News, updated CarPlay interface.
Judging by comparative tests, iOS 9.3 performs better than iOS 9.2.1 in terms of performance. However, some users complain about the accelerated discharge of the battery of their devices and problems with the activation of gadgets. In such cases, it makes sense to use the instructions for downgrading to the previous version of the OS. Another reason why a user may decide to downgrade is jailbreak. According to preliminary information, the upcoming exploit will not be available for the latest version of the OS, at least at first.
Note that we are talking about the return only on iOS 9.2.1 - for it, Apple still issues digital certificates. The situation can change at any moment.
Requirements:
Step 1: Download iOS 9.2.1 file from Apple servers by this link.
Step 2: Check that you have iTunes 12.3.3 installed. You can download the latest version from this page.
Step 3: Back up your data. This can be done in iPhone settings or iPad: iCloud –> Backup –> Create a backup, or by connecting a mobile device to a computer and saving a backup using iTunes.
Step 4: Turn off Touch ID/Password in General settings.
Step 5: In this step, you need to turn off Find My iPhone. The option is located in Settings –> iCloud.
Step 6: Connect iPhone, iPad or iPod touch running iOS 9.3 to your PC.
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 9.2.1 firmware file that you 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 9.2.1.
