I've been trying to fix my black screen brick for a while now. It occurred after the battery went dead in emuNAND on GW ultra. I have my original nand dump from GW menu. I soldered the pinouts to the SD adapter and checked everything over with an ohm reader. I've gone through a few adapters trying to get windows to view my 3ds as a drive. I've finally found one and it won't show up anywhere by My Computer. When I try opening the disk it shows a CRC error. I also have a RPi2B and a SD>microSD adapter. I've yet to find any way to unbrick that's compatible with my newer raspberry pi yet though. I just want to get this 3DS working again. Can someone please help me out?
