N3DSXL, with GW fastboot installed on NAND. I have not done anything that would impact/modify NAND, went to bed last night. This morning, when I boot, the N3DS screens stay blue before moving on to the dragon logo. If I remove the SD, the N3DS shuts off as it always had. It's like the N3DS's SD slot is faulty and can't read the MicroSD. Anyone got suggestions? **EDIT** Yeah! Turns out the SD was being faulty!! Cheers, tks guys.
