So my 3ds has a very odd problem. The 3ds switch was working just fine before formatting the system (green 3d light showed and the slider actually worked with the 3d). but after formatting, 3d refuses to work at all. Can't even get past the 3d check screen.. This 3ds has never been used for cfw and is on fw 3.0.0-4U. Is there a fix for this? I have already made sure all the connections were reseated properly and that the 3d switch wasnt broke at all, which it isnt.
