Here’s how to downgrade iOS 11.2.5 to iOS 11.2.2 on iPhone or iPad in preparation for a potential future iOS 11.2.2 jailbreak.

If you thought you were perfectly happy running iOS 11.2.5 on your iPhone or iPad until you heard about the potential for an iOS 11.2.2 jailbreak, then you will be pleased to know that it is still possible to downgrade while Apple is still signing that firmware version. Follow the process below to do exactly that. Make sure your data is backed up though but do remember that full backups made using iTunes or iCloud on 11.2.5 won’t be compatible for restore on iOS 11.2.2.

Step 1: First and foremost, you are going to need to have the latest version of iTunes running on your Mac or PC. You can grab this via the Update mechanism in the software itself, or by heading to apple.com/itunes/download/ and downloading the latest version for your platform. You are also going to need to have the correct iOS 11.2.2 IPSW for your iPhone or iPad. You can grab the relevant IPSW file for your device from here: Download iOS 11.2.2 IPSW Links And OTA For iPhone, iPad, iPod touch. Once done, proceed to step 2 below.

Step 2: Launch the Settings app on the iPhone or iPad and head to iCloud > Find My iPhone and ensure that this functionality is toggled into Off position.

Step 3: Now, with those two things done, it’s time to connect the device to the PC or Mac using the supplied Lightning cable. You also need to put the device into DFU or Recovery Mode. If you don’t know how to do that, then you can find the process below for your device type:

If you are still running an older device, such as iPhone 6s or iPhone 6 Plus, then you can use the old-school method of getting into DFU Mode, which involves holding down the Power and Home buttons together for ten seconds until the Apple logo appears and then releasing the power button while continuing to hold down the Home button until iTunes tells you that it has detected a device in Recovery Mode.

Step 4: You now need to be back concentrating on the Mac or PC. If you are using a Mac, hold down the Option key on the keyboard and click on the Restore iPhone… button in iTunes. If you are operating a Windows-based PC then it’s the Shift key that you need to hold down while clicking on the same Restore iPhone… button. Once prompted, select the relevant IPSW file from your computer.

iTunes will then go about its business getting that iOS 11.2.2 IPSW file installed on your connected device. Once it has finished, you will be left with a device running a clean installation of a firmware which will hopefully be jailbroken sooner rather than later using one or more of the Zimperium bugs when they become common knowledge.
