When I went to go unscrew the screws on the back of the 3ds to get to the motherboard, most of the screws were stripped. (I was only able to unscrew 2 of the screws on the back of the 3ds) The 3ds that I own is used from gamestop, and I think the person that owned it before me must of screwed up the screws. If you got any tips or anything I can buy to fix this issue, it would be greatly appreciated! Also ask me if you want pictures.
