1. Have you hacked your 3DS before?UPDATE:I dismounted sd card opened console and mount it again seems to work but still w8ing for a solution
I assume he means "turned on".How does one open a o2ds?
You certainly did something the last time you were on it or did something to the SD card, the console just doesn't do such a thing unless YOU messed with something you shouldn't have...I installed cfw (B9S) 2 weeks ago and i just tapped the power button to open :/
