Apple closes the iOS 15.6.1 authentication channel, but can still downgrade iOS 15.7 from iOS 16

Thanks to CTOnews.com netizens for the clues of tomato fried tomato delivery! CTOnews.com Sept. 20: Apple iOS 15.6.1 was launched to iPhone and iPad users a month ago, with important security fixes attached to the update. However, with the release of the official version of iOS 16, Apple has closed the authentication channel for iOS 15.6.1.

Apple iOS 15.6.1 was released on August 17, fixing the overall bug Bug and improving performance. Apple has also fixed two major security vulnerabilities through updates. Both vulnerabilities allow applications to execute arbitrary code with kernel privileges without the user's consent.

CTOnews.com learned that users can no longer downgrade iPhone, iPad, and iPod touch software to iOS 15.6.1. This has a direct impact on users waiting for jailbreak tools.

However, there is still a way to downgrade from iOS 16 to iOS 15, as Apple has also released the official version of iOS 15.7, which is reserved for users who do not want to upgrade the official version of iOS 16 for the time being.

IOS 15.7 official version fixes security issues with contacts, maps, Safari, Safari extensions, shortcuts, and WebKit, as well as several kernel vulnerabilities. Apple said that one of the kernel vulnerabilities has been actively exploited, so users who cannot update to iOS 16 should install iOS 15.7 and iPadOS 15.7 as soon as possible.
