FutureRestore now supports iOS 11
As you already know, Tihmstar, the developer of FutureRestore, clarified that he will not update it for iOS 11.
Now since this tool didn’t work with iOS 11 out of the box, some users erroneously deemed iOS 11.2’s SEP to be incompatible with iOS 11.1.2.
Thankfully, a new developer who goes by the name, firstEncounter, just released a much-needed update. It will now support all versions up till iOS 11.1.2.
He patched it in accordance with iDeviceRestore. For those who don’t know, FutureRestore is built upon iDeviceRestore utility.
Therefore, all changes made in iDeviceRestore need to be incorporated in this tool as well.
The developer also fixed some bugs and made everything compatible with the latest iOS 11.2 SEP. You can now try it out for yourself and see how it goes.
Which firmware can I upgrade/downgrade to?
According to the developer, upgrading from iPhone SE from 9.3.3 to iOS 11.1.2 was very smooth.
Moreover, eminent developer Coolstar also succeeded in updating his iPad on the exact same setup.
The new fork of version 90 will allow all users to upgrade and downgrade from and to iOS 11. Here are a few use cases for this version –
- Update from iOS 9 to iOS 11.1.2.
- Update from iOS 10 to iOS 11.1.2
- Downgrade iOS 11.1.2 to 10.3.3 on A7-chipset devices (not tested yet).
Remember, it won’t allow upgrading from iOS 11.x.x to 11.1.2 because you can’t set nonce on those versions. Once a nonce setter tool drops for those versions, you will be able to do that.
Also, 10.3.3 downgrade should work in theory. However, developers are yet to try it so wait it out till I give you the all clear.

How to use FutureRestore to restore to iOS 11.1.2
Step 1 Firstly, you will need to set nonce in NVRAM.
- If you are on iOS 9, you can do this using cl0ver.
- If you are on iOS 10, you must use iOS-Kern-Utils.
Step 2 Fire up your Mac. If you don’t own a Mac, you must set up a Virtual Machine on your Windows or Linux computer.
Step 3 Follow this tutorial and ensure you change the SEP value with that of 11.2. The restore command remains exactly the same.
