How to downgrade iOS 8 to iOS 7.1.2
If you’re interested in downgrading your iOS device from iOS 8 back to iOS 7.1.2, you can still do so for a limited time. Obviously, your device must be capable of running iOS 7.1.2 in the first place, so devices like the newly released iPhone 6 and its larger brethren, the 6 Plus, do not qualify.
Downgrades are only possible when Apple is signing the firmware that you wish to downgrade to. Traditionally, Apple is fairly fast with its cutoff point, as it usually stops signing firmware that’s not the current release, in short order.
As of this post, Apple is still signing iOS 7.1.2, so if you wish to downgrade, you better act fast. Inside, we’ll walk you through downgrading to iOS 7.1.2 on an iPhone 5s, but the same rules apply to any device that is currently running iOS 8, but is capable of running iOS 7.1.2.
