Apple stops signing the iOS 9.2 firmware, making it impossible to downgrade

Apple stopped signing iOS 9.2 firmware for iPhone, iPad and iPod touch on Thursday, which prevents users from running downgrades of iOS 9.2.1 to iOS 9.2 via iTunes.



Apple uses a special signing process in iTunes to assure users that they remain in a current firmware. This signing process, although frustrating for jailbreaks that are often required to upgrade to the latest version of the firmware prevents users to downgrade to an earlier version of firmware and helps keep business customers in a modern launch .

This is what keeps users updated with the new features and security enhancements, and ensures that your iOS devices are running better than Apple updates it has to offer. It can be said that is one of the reasons why iOS is one of the safest mobile platforms today.

Overall, Apple terminate your subscription iOS 9.2 does not affect anything directly to most users, since iOS 9.2.1 and iOS 9.2 are essentially the same, the first of which has just a few additional security fixes and performance improvements over the iOS 9.2. The new version was released a few days ago, leaving some faster devices.

As there were no major innovations and changes in the update of iOS 9.2 to iOS 9.2.1, and especially any bug or larger issue that motivates users to downgrade, the news should not offend anyone, even because the firmware saw no jailbreak popular. That is, no one will regret for losing the ability to downgrade to iOS 9.2 jailbreak for reasons too.
