Following the release of iOS 15.2 to all users last week, Apple today stopped signing iOS 15.1.1 for iPhone 13 models and iOS 15.1 for older iPhone models. This means that users who have updated their devices to iOS 15.2 can no longer downgrade to iOS 15.1.1 or iOS 15.1.
iOS 15.1 was released in late October to all users, including the Wallet app’s COVID-19 injection certificate, FaceTime’s SharePlay, ProRes for iPhone 13 Pro users, and more. The update also brought a manual deactivation option to the iPhone 13 Pro and iPhone 13 Pro Max.
Apple stopped signing iOS 15.1 for the iPhone 13 models in November, as the devices received the iOS 15.1.1 update to fix a specific bug affecting the iPhone this year. Now with iOS 15.2, iOS 15.1 and iOS 15.1.1 are no longer signed for any iPhone and iPad models.
Reversals to older iOS builds are often used by those who jailbreak their iPhones. Recovering an iPhone or iPad to an earlier version of iOS may also be useful for users who experience significant bugs after upgrading to the latest version of iOS.
If you’re having serious issues with iOS 15.2, unfortunately, you will now have to wait until a future update rather than downgrade to iOS 15.1.1 or iOS 15.1, iOS 15.3 beta users can no longer downgrade to iOS 15.1.1 . . iOS 15.1 either.
