Hey, so i had a few minor issues with my nN3ds XL. The issue i'm facing now is that the ABXY, Nub, Select, and start are not responding at all. I had a minor issue when i reassembled it with it not wanting to boot but i just checked and re fit some cables and it was fine. I checked the obvious ribbon cable that goes across to the motherboard but i guess i'm missing something. any help or info is much appreciated.
