I was transferring my daughters 2DS info to a N3DSXL. Stupidly I unlinked the NNID first thinking I needed to free it up since I know you cant do a system transfer on non 10.5 firm. So I realize I cant and needed to restore on 2ds then relink NNID, then sys transfer. It somehow broke the system. So I did the manual transfer and it now has the friend list she had, but she seems to have a new Friend Code. So all her friends are listed but they have a different code on their end so no one shows online.
