Trying to get it to work on my 3DS XL (which is updated to 6.2.0-12U), but it just wont. I'm getting the whole "hold power button to power off" thing. The icon is Dorasu (white shirt and his hand up), and the system info says the card is working on 6.2.0-12. I don't know what's up. It is a revision C with the correct website at the bottom of the cart. The only thing it lacks is the 6.1 icon on the front (which isn't a big deal I assume?). I've tried upgrading it again to the latest, but I just get a card check fail. Any input?
