Apple shuts down iOS 12.2 authentication channel users cannot downgrade to this version through iTunes

Apple officially closed the iOS 12.2 verification channel today after Apple released the official version of iOS 12.3 ten days ago. This means that you can no longer downgrade from iOS 12.4 Beta, 12.3 to the previous iOS version. Currently, however, iPhone 8 Plus (Global) and iPhone SE can also support iOS 12.2 authentication.

When Apple stops signing the old version of iOS, it means that users can no longer be downgraded to that version through iTunes. Operations such as demotion are common among users waiting for jailbreak updates, but downgrades are sometimes useful for those who have updated to the latest version of iOS, especially when it comes to a major Bug.

In previous versions of Apple's iOS 12.3, televisions with "alternate playback 2" were supported. The original up-slide clear background animation is back in iOS 12.3. This update also includes problem fixes and improvements.
