If you are one among those users who love the jailbreak thing, you may wonder if you can downgrade from iOS 9.1 to iOS 9.0.2? The answer is “No.” Apple has stop signing iOS 9.0.2, that means all the iPhone users who have upgraded iOS version from iOS 9.0.2 to iOS 9.1 will not be able to go back to the older version.
Pangu Jailbreak tool is already available for iOS 9, iOS 9.0.1 and iOS 9.0.2 that is quite smart to jailbreak iPhones in few minutes. Apple has always tried to block jailbreak tools in new updates, but it never got stopped, and it seems impossible. Pangu team must be working on Jailbreak tool for iOS 9.1, and it is expected to arrive soon.
Blocking iOS downgrade option is not a new thing for Apple. iOS 9.1 fixed many bugs of iOS 9.0.2, and brought new emoji, new wallpapers, enhancement for live wallpapers and many other fixes. So upgrading the iOS version makes sense, but once you do, you are stuck there. You can’t downgrade and jailbreak the device. You will have to wait for the new Pangu tool update.
