I think I wasn't clear enough in my last post because I was rushed and I panicked. So I helped my friend with installing A9LH and Luma on his Old 3DS but now we have a problem. We were on the 2.1 CTRNAND Transfer section on the guide and we should delete the CTRNAND Transfer files but since I was sleepy I said the wrong thing and we somehow managed to delete the NANDmin.bin and NANDmin.bin.sha files. Now my friend is stuck on 2.1.0 without any backup to restore with afterwards. What do I do now? Do I just update the system to start over? Do I continue the guide until I'm at the 9.2 CTRNAND Transfer (I don't know how since I need to restore the backup before I should do the transfer if the backup was not functional) A step-by-step guide on how to fix this would be really appreciated! I'm really sorry for the bump but I wasn't clear enough before and I got several different answers.
