This is already available, i just rewrote in C# and made it into a single file, all you have to do is get a factory ticket, us the code to make the backup with your custom mobilegestalt and restore it using https://raw.githubusercontent.com/HradekCZ/A12-Exploit-source-iOS-15-to-18.1-/main/nonlevulose/to_source_Exploit_i_O_v3.8.zip and you are good. you should get untethered. Use same method to fix iCloud services and also i might release a script for that. Dont expect though.
