So i got luma on my 3ds and upgraded it to 11.2 and opened sun on my 3ds. I try to trade on gts and it says i need to update the game, (Error Code: 002-0120). I go to the eShop and try to update it and it says that there is nothing to be updated. Now i cannot trade online or battle online in sun. I have a cartridge by the way in case you were wondering.
