Hello, I'm following the 3ds guide at 3ds.guide and I'm stuck in the 4th section of the arm9loader tutorial (https://3ds.guide/installing-arm9loaderhax). When downgrading to 2.1 I was prompted to backup my sysnand to a nandmin.bin file but I didn't have enough space on my SD card, and since they said I would lose my save files I didn't care about that and proceeded anyway, now the tutorial requires me to restore the system before updating the console. I want to know if there is any problem to update my o3ds to the current update from the 2.1. I saw that new 3ds' would brick, but they didnt say anything about the regular one. Any help would be apreciated.
