How to Futurerestore to iOS 15.1(.1) on Ubuntu using VMware on Windows

Restoring futurerestore takes a very long time. You must be careful not to touch the terminal in the middle of the process, thinking it is stuck.

First, iOS / iPadOS 15.3.1 must be signed.
If the signature expires, the SEP will be incompatible with Face ID devices and Face ID will break.
For Touch ID devices, SEP is compatible and usable with iOS 15.4.

Jailbreaking an iOS (iPadOS) 15.1(.1) device is rootless JB and will result in a different environment than before, so please do so at your own risk.

日本語の解説
========
はじめに、iOS (iPadOS) 15.3.1が署名されている必要があります。
Face IDのデバイスの場合、15.4とSEPの互換性がないため、署名が切れるとFace IDが壊れます。（15.4を使用した場合）
Touch IDのデバイスの場合は15.4とSEPの互換性があるため利用できます。

iOS/iPadOS 15.0から15.1(.1) までの脱獄はrootless JBになるため今までと環境が異なります。（iOS 15.0からroot file system sealedが追加されたため）
iOS 14で留まるのも問題ないので、実行する際は自己責任のもとで行ってください。
