iOS 7 Tethered Downgrade
In this guide, we are going to be tether downgrading A7 devices (iPhone 5s, iPad Air 1 and iPad Mini 2) to iOS 7. Keep in mind, the information you will see here focuses on iOS 7 for A7 and isn't intended for newer versions (Downgrades to early iOS 8 betas are usable although newer versions of iOS 8 will boot but won't be usable). This guide should cover all iOS 7 versions (7.0-7.1.2).
There's no warranty given. Follow this guide on your own risk. If something goes wrong, a restore should fix everything.
