Apple began to stop allowing restore to iOS 7.1.2 version

As of today, Apple has begun to stop allowing users to return to iOS 7.1.2 firmware, which will prevent users from downgrade from iOS 8 back to iOS 7 (via iClarified).

This means that if users are not satisfied with the changes that iOS 8 or some new version bugs fail, it cannot be downgraded to iOS 7.1.2.

Apple's decision to stop this is not an unusual issue, as it will often stop previous versions of iOS immediately after releasing a new version. iOS 8, Apple's latest mobile operating system was officially released on September 17.

Released on June 30, iOS 7.1.2 is the latest version of iOS 7 which includes bug fixes, improved security and fix email attachment encryption issues. Current iOS 7.1.2 is still available for iPhone 4 devices as well as iOS 8 operating systems installed on iPhone 4s and later.
