Users who had installed a fresh iOS 9.2 update have an opportunity to return to the previous version of the OS. Apple traditionally after the release of each new version of the operating system reserves such an opportunity for a short time. After a day after the release of the update, the company issues certificates for iOS 9.1.
Released on December 8 iOS 9.2 update improves the performance of the whole system and improves the performance of the functions in Apple Music, Mail Drop and Safari.
iOS 9.2 is reasonably robust and massive complaints of errors have been reported yet. However, if you encounter this or that problem — rapid discharge of the battery or unstable Wi-Fi — you may want to perform the downgrade procedure — recovery to a previous stable firmware. It is only version iOS 9.1 — Apple issues digital certificates for it. It is worth remembering that the situation could change at any moment.
Requirements:
- iPhone, or iPad running iOS 9.2.
- IPSW-file iOS 9.1.
- The latest version of iTunes for Mac or Windows.
