SO I used my 3DS to system transfer my CFW to a friends system. I then restored my sysNAND. I formatted his system so my NNID and Friend Code wouldn't be on his system. Today all my legally downloaded items vanished and I cannot log into my NNID because I am told its being used on a different system. So question is, how can I get my NNID back onto my 3DS. Nintendo won't help. Am I screwed?
