Apple no longer signs iOS 15.1 and 15.1.1: restore and update blocked

Apple has stopped signing both iOS 15.1 and iOS 15.1.1 on its servers. This means that it is no longer possible to update or restore your iPhone or iPad to one of the two versions. As a reminder, Apple had already stopped signing iOS 15.1 last month, but only for iPhone 12 and 13. This concerns all models now.

End of signing for iOS 15.1 and 15.1.1

iOS 15.1 was released in final version at the end of October. This was the first “major” update of iOS 15. It was notably the opportunity to have the SharePlay functionality. Apple also took the opportunity to make improvements to the Camera, Maps, Translate, Home and Shortcuts applications.

We were then entitled to iOS 15.1.1 in mid-November. For the moment, this version was only offered to users with an iPhone 12 or 13 (as well as the mini, Pro and Pro Max variants). This is explained by the fact that the update corrects a bug with calls and it only concerned the latest iPhones.

Here we are today with iOS 15.2. Apple released this update as a final release a few days ago. The next one will be iOS 15.3. Both developers and public testers have recently been eligible for a beta.
