CFW: I formatted my 2ds's sd card and now it wont turn on [post #17]Yes its goes blue for an instant then stops
Edit 1 - You can skip ahead most of those steps for any SD cards that you already successfully tested in H2testw and were reformatted in those [ FAT32 + 32 KB cluster size, etc ] settings.
~ For you, start at step 5.
Edit 2 - You might need to attempt multiple card reinsertions or different cards before the 3DS gets a good read. Also try the battery trick to see if that helps if it does not pick up.
