This wouldnt be a big deal if i didnt format 3 times and try it seperately 3 times, but it seems whenever i downgrade my old 3ds's rednand to 2.1, i get an error has occurred each time. Could somebody point me to what im doing wrong? I've downgraded 2 n3ds's and 3 old 3ds's and this has never come up before. Yes im using the same downgrade files that i've copied onto the sd card multiple times.
