Apple has a policy of keeping its ecosystem up-to-date, and the company stops signing older iOS versions shortly after officially releasing a new one, to ensure that all iPhone users are running the latest software on their devices. Something that has also happened with one of the latest iOS versions.

You can no longer install iOS 15.1.

Just last Tuesday, according to the iMore site Apple finished signing iOS 15.1, which means that users who upgraded their devices to iOS 15.1.1 or iOS 15.2 beta can no longer downgrade to iOS 15.1. This comes a month after the company stopped signing the iOS 15.0.2 firmware.

iOS 15.1 was released for all users at the end of October with some new features, such as the COVID-19 vaccination certificate in the Wallet app, SharePlay in FaceTime, ProRes for iPhone 13 Pro users, and more. The update also brought an option to manually disable Macro mode on the iPhone 13 Pro and iPhone 13 Pro Max.

A few weeks later, Apple released iOS 15.1.1 to fix some bugs that affected iPhone 13 users. According to the company, older versions of iOS 15 have a bug that causes phone calls to drop unexpectedly.

You can’t downgrade from iOS 15.1.1 down

Reverting to previous versions of iOS is something that people who jailbreak their iPhones often do. Restoring an iPhone or iPad to a previous version of iOS can also be useful for users who experience major errors after updating to the latest version of iOS.

Thus, If you have experienced any serious issues with iOS 15.1.1, unfortunately you will have to wait for a future update instead of downgrading to iOS 15.1, or choose to install the beta of iOS 15.2. In fact, users running iOS 15.2 beta can no longer downgrade to iOS 15.1 either. If you want to install the beta, we will tell you how:
