Apple stops signing iOS 15.2, blocking downgrades from iOS 15.2.1

After earlier releasing iOS 15.2.1, Apple on Thursday stopped signing iOS 15.2 for all iPhone, iPod Touch and iPad models. This means users can no longer downgrade their devices to iOS 15.2.

iOS 15.2 was released to the public on December 13, 2021, and includes Apple Music Voice plans, new app privacy reporting in Settings, child safety alerts using Messages, digital legacy, and more.

A month later, on January 20, iOS 15.2.1 was released, fixing a CarPlay bug and a security vulnerability discovered in HomeKit that could cause an iPhone or iPad to repeatedly crash.

People who jailbreak their iPhones often use reverting to an older iOS version. Restoring an iPhone or iPad to a previous iOS version sometimes also helps users who encounter critical errors after upgrading to the latest version of iOS.

If you encounter any serious issues while using iOS 15.2.1, unfortunately you will now have to wait until a future update instead of downgrading to iOS 15.2. Users running the iOS 15.3 beta can also no longer downgrade to iOS 15.2.
