Apple has stopped signing iOS 15.1 and iOS 15.1.1, preventing users from downgrading their iPhone after installing the latest iOS 15.2 update.
If you have encountered bugs and other issues with this release, you’ll now have to stick with it until Apple rolls out iOS 15.3, which this week entered beta testing ahead of an official public rollout.
Apple stops signing iOS 15.1 and iOS 15.1.1
Apple rolled out iOS 15.1.1 last month to fix some rather frustrating bugs affecting the iPhone 13 lineup. Older models were left with iOS 15.1, which worked perfectly fine (for the most part) on earlier Apple devices.
Now, following last week’s release of iOS 15.2 for all iPhone models, both iOS 15.1 and iOS 15.1.1 are no longer being signed by Apple. That means it’s not possible to downgrade to these versions if you’ve already updated your device.
If you’re still running iOS 15.1 or iOS 15.1.1, there’s no need to worry. This change doesn’t affect existing installs, so you can continue to use your iPhone as normal. However, once you update, there’s no way back.
iOS 15.3 already in testing
There have been no reports of serious issues in iOS 15.2, so you shouldn’t worry about upgrading. In addition to the usual fixes, this release brings new privacy and child safety features, and support for Apple Music’s Voice Plan.
Apple has already begun beta testing iOS 15.3, which promises to eliminate more bugs. We wouldn’t recommend installing it on primary devices while it’s in testing, but it is available through Apple’s public beta program.
