You do realise thats the part of the guide where you tell people to back up there SD and copy the files back over after the format = solution its still installed
If you have the time, please check my tutorial again if it's correct.
Basically what I did is:
- added steps to install FBI.cia with FBI through HomebrewMenu before formatting emuNAND
- added additional step to install FBI again into sysnand if you unlinked and need it there (basically just repeating the steps to install FBI.cia via Pasta)
- took out the entire FBI H&S Inject and decrypt9 stuff
I hope I understood it correctly. I can not test this but logic says that's how it works.
