#00 screwdriver is too big... probably need a #000

The correct screwdriver should be a JIS, or you can get a screwdriver specific for the 3DS from other sites for less than $2

Had to give up at this point. Tried using the ifixit #00 phillips screwdriver to take out two screws and ended up stripping them.

Stuck at the same spot, those screws are in there really tight.

Ruined my screws because of incorrect head, thanks!

I had so much trouble with these screws, I gave up. Unfortunately, I can't accept failure so tried again. I figured out if you turn it right before you loosen it worked. Maybe it was just me, but I turned it right then kept pressure as I turned to loosen. I was surprised I hadn't stripped any screws out.

Does anyone have any idea of how to remove these screws. I've pretty badly stripped the screws and I've gone to 20+ pages trying to figure this. I'm considering just prying the !@#$ thing.

I used a #00 Philips 1/8" bit with no problem; however, the narrow diameter of the counter sunk hole can inhibit making secure contact with the screw head. You can be using the right bit (#00) but if the diameter of the bit shaft is too big you won't get proper contact.

I found this to be an excellent guide. Thanks

If anyone can point me to a link to purchase the 9 screws, let me know. Contacted Nintendo and they said I'd have to send it in. Email me at
