Bad news for those looking to downgrade their devices to iOS 10.2.1 or iOS 10.3 as Apple has closed the signing window a while back. iOS 10.2.1 & iOS 10.3 no longer being signed by Apple – iOS 10.3.1 is the way to go now.

Whenever Apple releases a new firmware version for iPhone and iPad users, users have the option to downgrade back to the older software using iTunes. But this is only possible for an extremely limited period of time, after which you have to stick with the latest publicly available iOS release. Today though, Apple has flipped the switch and stopped signing iOS 10.2.1 and iOS 10.3. This means you can no longer downgrade your iOS device to the aforementioned firmware versions no matter what you do.

But, of course, you might have your own reasons for sticking to older firmware, such as battery life related issues. Or maybe you are hoping that an iOS 10.2.1 jailbreak may arrive in due course. That’s completely understandable, and waiting has, thus far, proven to be fruitful for a lot of people out there. Maybe you’ll get lucky in the time to come as well. But keep in mind one thing: there is absolute silence from the world of jailbreaking, so don’t hold your breath for a new solution for Apple’s latest firmware release just yet.

Still, if there is an update from the jailbreaking front, we will definitely inform our readers about it, so stay tuned for more in the days to come.
