Topic: 3ds streetpass error

me and my friend updated to 3ds xl when they were relesed (i know i should have asked about this way before) and after we systems tranfered it dodnt work to streetpass. Wich had worked like a charm before. And now dont work at all. And we dont know anyone else with a 3ds to try it with

I've transferred and so have some of my friends and we still tag each other just fine. There was a different bug with removing the battery where people would stop being able to streetpass people they had tagged before, and deleting the miis from the plaza would allow people to start tagging each other again. If you're sure the wireless is on and streetpass is activated on both systems to be able to tag, I would try deleting your friend's mii from your plaza and having them delete your mii from their plaza to see if you can get them to start tagging again.
