Downgrade iOS 16.1 to 15

Yes, it’s possible to downgrade iOS 16.1 to 15.7.1 without losing data! It’s a three-step process, but it can be achieved by any iPhone user with the help of a computer, Lightning to USB (USB-C) cable and an Internet connection!

Downgrade iOS 16.1 To 15.7.1

A direct downgrade has never been possible because iOS 15.7.1 has never been signed for devices that are already running iOS 16!

More, Apple has recently unsigned iOS 15.7 which was also signed for iOS 16 running devices, thus closing this downgrade option!

However, iOS 15.6 RC is still signed for all compatible devices! Whether this is a loophole left by Apple intentionally or not is less important.

The big news is that you can downgrade from iOS 16.1 to iOS 15.6 RC (19G69) and then update over-the-air to iOS 15.7.1!

We’ve decided to test it out for you after receiving numerous requests in the comments section here on the website and on our YouTube account.

How To Downgrade iOS 16.1 To 15.7.1
