Apple has stopped signing iOS 15.3.1, which means it now blocks downgrades to this version of iOS on the iPhone. This means that anyone who wants to install any version of iOS must now install iOS 15.4.
Apple has been known to stop signing older versions of iOS as it releases new versions to ensure users are running the latest version of Apple's software for the iPhone. New versions of each software include not only new features and bug fixes, but also performance improvements and security updates.
Now anyone trying to restore an iPhone will only have iOS 15.4, as Apple now blocks downgrades to iOS 15.3.1. Those on the developer and public beta train can, of course, always install the latest iOS betas.
While some appreciate the ability to downgrade to an earlier version of iOS as a fallback to problems with a newer version of software, this openness is usually short-lived. If you're using iOS 15.4 and are having issues, you'll have to wait for Apple to release a newer update.
iOS 15.4 is the latest public version of iOS 15 and brought the ability to unlock your iPhone with a mask and a number of other smaller features.
