Alright, so I updated my R4i-SDHC 3DS to the new version, and it worked like a charm, but after a day of playing, I turned it off. I turned it back on the next day, and it gave me the error "An error has occurred." with a blackscreen. I think the problem is that I didn't upgrade using the "upgrade" function from the options menu, but now I'm stuck. I can downgrade my card, but because I already updated my 3DS, it won't work. I have a DS Lite, but the card reader is broken. So what can I do? I was thinking about formatting but I would lose all my Mii's, my streetpass(and it's pretty hard to get friends for streetpass since where I live 3DS doesn't have a big fame), my play coins, and everything. Is there a way to fix this without having to reformat or I'm screwed?
