One of the many security updates included in iOS 9.1 happened to block the iOS 9.0.2 Pangu jailbreak that the team of hackers released to the public last week. Unfortunately, we have to take the good with the bad when we upgrade our iOS devices, but iCrackUriDevice has instructions for how to downgrade back to iOS 9.0.2 in case you still want to jailbreak.
Before we begin, it’s worth noting that this method will only be possible as long as Apple continues to sign the 9.0.2 firmware. Once the company stops, you won’t be able to downgrade the traditional way.
Also, any data that you’ve saved since updating to iOS 9.1 this week will not be transferred when you downgrade, so be sure to backup your phone and restore it once you’ve finished downgrading if you don’t want to lose anything.
All finished? Ok, let’s move on to the downgrade itself:
Step 1: Download the iOS 9.0.2 IPSW from IPSW.me. Just choose your device from the first dropdown menu and then select iOS 9.0.2 from the iOS version menu. Click download.
Step 2: Disable Find My iDevice in Settings -> iCloud on your phone or tablet.
Step 3: Open iTunes. Navigate to the Summary page for your device. Hold down Shift (on Windows) or Alt/Option (on Mac) and click on “Restore iPhone.” A pop-up should appear asking you to choose a file — choose the IPSW file you downloaded earlier.
It’s a relatively simply process, but if you’d rather watch a video to ensure you don’t screw it up, you can follow along below. Once you’ve finished, be sure to check out the video dedicated to the iOS 9.0.2 jailbreak to learn how to jailbreak your downgraded device.
