The iOS15.1 system channel is closed and cannot be downgraded!
|
According to the news from the Institute of Core Research, Apple has currently closed the verification of the iOS 15.1 system version. This means that users who have updated to iOS 15.1.1 or iOS 15.2 beta can no longer downgrade to iOS 15.1. It is understood that Apple usually stops verifying older versions of iOS within a few weeks after pushing the official version update. For some users who have updated to the latest iOS system, when they encounter major bugs, downgrading is sometimes very effective. This is also the reason why Apple will wait for a while before closing the verification channel for older iOS systems. The official version of Apple iOS 15.1.1 mainly improves the call drop problem of iPhone 12 and iPhone 13 models. In addition, it also adds a simulcast sharing function and the function of shooting ProRes video on iPhone 13 Pro and iPhone 13 Pro Max. At the same time, a verifiable COVID-19 vaccination card was introduced in Apple Wallet. |
