I'm trying to ask you guys here, because I'm so stupid and deleted my FBI in freeshop app.

It was described there as a game. I got old menuhax and 11.0 emunand. I found on forum that I should go to luma settings and check ARM9 Access and open hblauncher open FBI and install it. I copied new FBI on SD and when I did it with this acess ARM9 option checked console freezes on opening FBI in HB launcher and now without this option checked I got Fatal Error Backdoor Kernel not installed. So anyone could help? Please
EDIT: It seems like older version FBI works only in HBL but can't install nothing without ARM9 acess, and newer FBI is not working at all like it didn't work with my menuhax (Fatal Error) I'm in endless loop
