The single 3ds method is where you inject a blank nnidsave and a hex-edited SecureAinfo file, nothing else. You then have to run FreeMultiPatcher in order for it to work correctly.I know, i removed my nnid, but i get an eshop error either way with the new nnid. I'll try to find the error code i got if i can. It's not the banner error, it's different, and only of i have an nnid loaded. Also, online one?
