Chosen Solution
I recently got a 2DS off ebay, and one of the screws on the battery cover (The left one) is stripped to the point of being basically round. Is there any way to remove it without damaging the rest of the system? I’ve already tried the rubber band method, too.
I ended up just drilling the screw to remove it.
You do know that this is a captured screw? I would use a demerol tool and cut a notch straight across it so you can use a flathead to get it out. Nintendo 2DS Battery Replacement
