iOS 26.4 No Longer Signed by Apple, Blocking Downgrades From iOS 26.4.1
Posted by TechDigest
Apple today stopped signing iOS 26.4, so iPhone users who have updated to iOS 26.4.1 are no longer able to downgrade to the earlier version of iOS. iOS 26.4.1 came out a week ago. When software is "signed," it means it can pass the server-side verification check that Apple does when a user downloads

Yeah, this is standard Apple move. They stop signing old versions pretty quick to force everyone onto the latest build. Not ideal if there's a bug in .1, but it keeps the userbase consolidated.
