Apple closes iOS 15.6.1 verification channel, but iOS 15.7 can still be downgraded from iOS 16

With the continuous development of the times, people have gained a lot of convenience in the development of science and technology. Recently, Apple's series of mobile phones have been discussed by everyone, not only mobile phones, but also systems. In addition to the release of iOS16, people have also paid much attention to the old system. Recently, Apple officially closed the iOS 15.6.1 verification channel, but iOS 15.7 can still be downgraded from iOS 16. Let's get to know.

Apple iOS 15.6.1 was pushed to iPhone and iPad users a month ago, and the update comes with important security fixes. However, with the official release of iOS 16,Apple has closed the verification channel of iOS 15.6.1.

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

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, users still have a way to downgrade from iOS 16 to iOS 15, because Apple also released the official version of iOS 15.7, which is reserved for users who are not willing to upgrade the official version of iOS 16.

The official version of iOS 15.7 fixes the security problems of contacts, maps, Safari, Safari extensions, shortcuts and WebKit, and also solves multiple 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 as soon as possible, and iPad users should update to iPad OS 15.7.

Apple closes the iOS 15.6.1 authentication channel, but iOS 15.7 can still be downgraded from iOS 16. So if you want to experience iOS 16, you should take advantage of it. Otherwise, if iOS 15.7 is also closed, the downgrade will be very troublesome. Many small partners also say that iOS 15.7 is a good system for retirement.
