I just did the DSiWare Downgrade from my sister 2DS to my N3DS. But the problem is that, I don't want anything from my sister. I even got her Mii. Ugh... (NNID based) How I can change my FC? or even more interesting.... My FC from my banned 3DS? All my streetpass and mii data from my Main banned 3DS? I can just dump those files or use JKSM to dump those and restore to my N3DS?
