Thanks to CTOnews.com netizens for the clues of tomato fried tomato delivery! CTOnews.com April 9, Apple closed the iOS 16.3.1 authentication channel after releasing an update to iOS 16.4.1 yesterday, which means that iPhone users can no longer be downgraded to this version of the system. At present, iOS 16.4, iOS 16.4.1 and iOS 16.5 beta versions can still be installed normally.

According to CTOnews.com, iOS 16.3.1 is a small update released on February 13, which mainly includes some bug fixes, safety improvements and car accident detection optimizations for iPhone 14 series models. Apple usually stops signing the old version of iOS shortly after the new iOS version is released to encourage users to keep the system up-to-date.

It is predicted that the iOS 16.4 authentication channel may be closed later this month, so users of iPhone who want to downgrade to this version need to hurry.
