FROM Godslash - Admin on the SC Forum, I know SlayerDX has posted in the 3DS fix post but for ALL those who have had WHITE SCREENS on the DS PHAT/LITE and THERE IS NO CARD INSERTED IN THE DS CAME CARD SLOT messages: Note for Fireware v1.08 of DSTWO We found there is a reset bug in v1.08 Fireware of DSTWO. Somethings the cart cannot be recognized after resetting. We are addressing this issue, we thought that may be because the amount of data is very large when 3DS boots, but the time spent for reset is too short, CPU is not been initialized. We are modifying the booting code now, we will release a new version A few days later. Btw, please make sure to upgrade DSTWO fireware on the DS console, never on a 3DS console.
