Hello, I have a N3DSXL that I hacked using the system transfer method. I used my wife's 2DS. It turns out that we now both share the same friend id. I believe the only way for us to get unique IDs is for one of us to restore to factory. I actually just tried this but was completely unable to backup Health&Safety, saying "slot0x25keyx not set up". So, I'm restoring my 3DS from a backup now, but in the future, is there a way to go about this? Am I doing something wrong? Any help would be greatly appreciated. Thanks!
