I was messing with fbi to delete titles and then it said error occurred and I needed a reboot. After that I opened my 3ds and it says Ctrfirm is not found and made me quit. I don't care about my game saves or my 186 legit badges I just want firmware back. I am using Lumas3ds with A9LH and have a backup from 1 week ago on nand.min. Do I backup with decrypt9? Or is there another method?!?!?!?!? Plz help!!!!!!
