How to Downgrade iOS to iOS 12.1.1 (Restore iOS 12.1.1 from iOS12.1.1.1)

Downgrade iOS to iOS 12.1.1 for iPhone, iPad…

Apple unveiled incredible firmware update for iOS users which is full of jailbreak tweaks and the features which was demanded by Cydia users as well.

The excitement is huge and so most of the users have taken a hurry decision to upgrade their firmware which is now reversible to iOS 12.1.1.

As iOS beta is available for public testers so more and more users are trying iOS and most of them are unhappy with the buggy beta.

Yeah, PanGu has demoed iOS jailbreak which was based on beta firmware, but it won’t be out until the final version but before that PanGu may release iOS 12.1.1 and this could be another reason for downgrade iOS to iOS 12.1.1.

We had tried iOS 10.3 which was buggy and apps ware crashing with slow control center access. Couple of times Notification center and control center was not accessible. iOS 10.3 lockscreen widgets were buggy.

These were the primary reasons for downgrade iOS back to iOS 12.1.1 which is most recent and latest update. We know that there are thousands of users who want to know the exact process which we done to downgrade iOS to iOS 12.1.1.

Okay, here is the same exact steps with screenshot that would show you how to downgrade iOS to iOS 12.1.1 or any other stable version which could be iOS 12.1.1 at last. You won’t be able to downgrade iOS to iOS 9.3.3 or long back versions.

There are couple things which you should note before proceeding downgrade iOS12.1.1.1 to iOS 12.1.1 or any other version specially while downgrading…

  • iOS 12.1.1 is only the option to restore back from iOS which you should remember before proceeding. One more thing that it’s totally depend on Apple singing firmware. If Apple would stop signing iOS 12.1.1 you won’t be able to downgrade to iOS 12.1.1 and this is the same for iOS 10.1.1 too. Suppose, if Apple releases iOS final, Apple would stop signing iOS 12.1.1 and then you won’t downgrade to iOS 12.1.1 at any cost.
  • Backup is always recommended because if anything goes wrong, you’d have chance to get your data from previous data backup. So before starting iOS downgrade, I would recommend to keep backup.
  • You can restore your old iOS 12.1.1 backup from data backup which may be large so the time of downgrade iOS depends on your data backup size. But, if you’re restoring to fresh iOS 12.1.1 then you won’t need data backup at all and in this situation, iOS downgrade would be fast enough.
  • Before starting downgrading process, it’s always recommended to download or save Photos and videos with contacts and SMS to separate computer or device before thinking to downgrade iOS or any other firmware because this process may delete whole data from your device.

How to Downgrade iOS and Restore iOS 12.1.1

I have tried to cover each and every step which is necessary to know in order to successfully downgrade iOS to iOS 12.1.1 or the firmware which is compatible for restore. Take a look…

Step 1: The first and initial step is to download iOS 12.1.1 IPSW, You can downgrade to iOS 10.1.1 and if you willing so, you need iOS 10.1.1 IPSW in that case. In short, you need IPSW files to downgrade iOS to previous version. But again, you can use iTunes to restore most compatible and latest firmware to restore and in that case you won’t need iOS 12.1.1 IPSW to downgrade to iOS 12.1.1.

Step 2: You must know how to put your iPhone or iPad into DFU to downgrade iOS Keep a closer look at below steps…

  • When you connect your iPhone to computer, you need to turn off your device by following method.
  • Hold Power button which you use to turn on device and swipe to turn it off.
  • The next step is Hold Power button again at least 3 secs.
  • Now without releasing Power button you need to press Home button and hold it.
  • About after 10 secs release power button but don’t release home button until you see iTunes pop up that would show below screen.

  • Now the main step comes. You need to hold Option/Alt button if you’re using Mac or Hold Shift button if you’re using Windows to restore iOS 12.1.1.
  • You’d get below screen when you would perform above step to downgrade iOS where you can tap on Check updates or just restore iPhone to most stable recent update.

  • Select the IPSW file which you’ve downloaded in the first step. If you’re willing to Download to iOS 12.1.1, you need to browser and select iOS 12.1.1 IPSW file and if you’re planning to go back to iOS 12.1.1, choose that IPSW file and press “Restore and Update” button.

  • Just agree to the terms and condition and continue it. iTunes would load up IPSW files and continue downgrade iOS to iOS 12.1.1 whatever you’ve chosen in the above step.


Step 3: You’re welcome to comment system if you’ve any issues or confusion in downloading process. It may be possible that you encounter couple of iTunes errors while downgrade to iOS 12.1.1 or any version you want.

So, it’s always nice idea to ask the question from expert or the users who have already downgraded iOS previously.

Updated on 31-1-2017: Apple has stopped signing iOS 12.1.1. It means you can directly downgrade iOS to iOS 12.1.1. If you wanna downgrade to iOS 12.1.1, you need to use Prometheus or other TinyUmbrella or iFaith tool to downgrade.

      I hope you understand.
