How to Downgrade iOS 11.1.2 to 10.3.3 firmware [A7 Devices]

Downgrading to iOS 11.1.2 is possible but only on select few devices. Here’s a complete downgrade tutorial for iPhone and iPad devices with A7 chipsets.

Is a downgrade from iOS 11.1.2 possible?

A downgrade from iOS 11-11.1.2 to iOS 10.3.3 is possible. However, you must own an Apple device with A7 chipset to downgrade.

As you already know, Apple is still signing iOS 10.3.3 via OTA for A7 devices. This ensures you have a signed firmware, which is compatible with your target firmware.

Therefore, you can downgrade to iOS 10 provided you have SHSH Blobs for your destination or target version.

Here’s the complete tutorial for downgrading iOS 11 to 10 with SHSH Blobs. This tutorial was conceptualized by legacy developer Hacks4Live.

Compatibility

Here’s the list of all A7 devices that are supported –

  • iPhone 5s
  • iPad mini 2
  • iPad Air

Warning – Remember, don’t try this method on any device that doesn’t have an A7 chip. This process will not work with them and you risk bricking your device.

Requirements

  • A compatible iPhone or iPad
  • SHSH Blobs for your target version (iOS 10.3.3)
  • A computer running Windows, macOS, or Linux
  • FutureRestore

How to downgrade iOS 11.1.2 to 10.3.3 with SHSH Blobs

Step 1 Firstly, download NonceSet1112 tool and install it on your device. Once it’s installed on your device, set your nonce in NVRAM.

Step 2 Download the latest version of FutureRestore for Windows, macOS or Linux.

Step 3 Download iOS 10.3.3 IPSW file from ipsw.me.

Step 4 Open the IPSW file with 7Zip and transfer the following files to FutureRestore’s folder.

  • Mav7Mav8-7.60.00.Release.bbfw (This is or iPhone 5s Global only. You must use a different file if you are on another device.)
  • sep-firmware.n53.release.im4p (This file is present in the “all_flash” folder. You must determine which file to use from Battery Memory System Status Monitor app)

Step 5 Extract iOS 10.3.3 OTA Manifest from here.

Step 6 You should have the following files in your FutureRestore folder now –

  • iOS 10.3.3 IPSW file
  • Baseband file (.bbfw)
  • SEP firmware file (.im4p)
  • SHSH2 Blob

Step Run FutureRestore and enter the following command (without brackets) in Terminal to start the restore –

futurerestore -t [Blob name].shsh2 -b [baseband file].bbfw -p [Buildmanifest].plist -s [SEP firmware].im4p -m [Buildmanifest].plist [target firmware].ipsw

Step 8 Wait for the restore process to get over. Once it’s done, set up your device.

Step 9 Jailbreak your 64-bit iPhone or iPad with g0blin jailbreak here.

If you run into some error while restoring, just leave a comment below.
