iOS 15.4.1 Jailbreak

The Checkra1n and unC0ver jailbreaking tools have versions that are compatible with newer versions of iOS 14, but only Checkra1n is compatible with iOS 14.5.

Unfortunately, iOS 15.4.1, iOS 15.4, iOS 15.3.1, iOS 15.3, iOS 15.2.1, iOS 15.2, iOS 15.1.1, iOS 15.1, iOS 15.0.2, iOS 15.0.1, iOS 15.0, iOS 14.8, iOS 14.7.1, iOS 14.7, iOS 14.6, or iOS 14.5.1 are not supported by the tools.

UnC0ver’s most recent version is compatible with newer iPhones, including the iPhone 12 series. If you’ve been waiting to jailbreak your new phone, this is great news. Unfortunately, it is only compatible with iOS 14.3 and later. 

There is no way to downgrade your phone’s software to iOS 14.5 or earlier versions of iOS, so if you upgrade or have already upgraded to newer iOS software, you’re out of luck.

What’s Next

Apple has revealed the arrival of a new version of iOS 15, also called iOS 15.5 is currently in beta testing in preparation for its public release.

The release of iOS 15.5 is a milestone, but it appears to be a minor one. It will most likely include a mix of new features, bug fixes, and security patches.

The company has not confirmed a specific release date for iOS 15.5, and we anticipate that it will remain in beta for a few more weeks as Apple irons out the kinks. We currently expect the official release to take place in May or June.

If your problems are serious, or if you simply want to experiment with new software, you should download the iOS 15.5 beta onto your iPhone right now.
