  • Unscrew the four Phillips #00 screws along the top of the back cover.

  • The screws are held in place by locking washers, and will not come out of the back cover.

  • The comments section is full of unlucky souls who will tell you that the screws here through step 4 will strip incredibly easily. Press down fairly hard, and go slow.

Well done, thanks for the help, I had small problems with step 9 because of all those small parts but I managed to put everything back as it was. Thanks again :D

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

thomascroguennec, · Reply

#00 will work - but you must press down firmly and sort of jerk the screw out a few degrees at a time. If you don't press firmly, the screws strip very easily. Using #000 will strip the screws more easily.


I used a #0 without any issues and 0 stripped. I used the #0 for all screws internally and externally. The head was sharp and I applied adequate amounts of pressure when loosening the screw.

Ben Kevan,

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

I used Phillips #000 and it worked like a charm, i need to order a new SD board or do you guys think i should send it. What happened is that it got water damaged and everything works fine when i opened it everything looked fine no signs of water corrosion everything on the 3DS works exept it always give me a message saying the SD card is locked and i know for a fact it isnt locked i already tried using 3 different SD cards and none of them are lock protected and yes they are formatted as well. I need help

david hodson you are incredible. literally all you need to do is heat the screen up and pry it off and you make them take apart the whole thing

melody, · Reply

You've done this?


I have to ask the same question. If just the glass display is broken, and you're heating it up to remove the glass, is it really necessary to remove everything? Doesn't like like it is necessary


I just did it your way and it went fine. didnt even have to remove the battery. This is incredible misstep on the authors part.


I used a PH0x50, but it wasn't easy.

This may be a dumb question but where do I buy the 3DS upper screen?

John, · Reply

eBay... Just do a search for the 3DS Upper screen. $9.49 & it comes with the tools.

Gary Darnell,

The LCD screen I ordered came with all the tools I needed except a pair of tweezers. All in all it was about $14.00 and a little bit of my time.

Does anyone know where I can find the right bumper button for a 3ds? I can't find it on ebay must of damaged it playing smash bros.

Really wish I had read the comments first... How about instead of the warning saying to press down hardly and go slow, you say to use the correct screwdriver size like others mentioned in the comments. I not only stripped multiple screws, even after putting a glove on for more pressure, I bent my screwdriver from pressing down so hard. Granted it's a cheap jeweler's kit screwdriver, but it still would've been nice to not have that problem and be informed of the right size in the first place.

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

Demios, · Reply

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.

Nicole Bauer, · Reply

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.

use a dremil and make it a flat head

Ralph Prowant,

ruined my screws here too...what the !@#$ nintendo?

trying to survive a nuclear meltdown inside 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

Unscrewed the nine 6.3 mm screws using the J000 bit from the iFixit 54 bit driver kit without much effort & without stripping the screw heads. Just gotta really position the bit correctly on the screw to have a proper fitting & not strip the screw heads.

The screws didn't strip but the philips screw driver did? @__@

These are rough either way.

John Zhou, · Reply

I used a "Whia 273 - PH000x40" screwdriver and held it firmly pushing the palm of my hand on the yellow end of the screwdriver and rocked the screw slightly (counter clockwise and clockwise) until it started to move. Then, without letting up on the pressure I carefully backed it out. The screwdriver is excellent because it is hardened (unlike some cheapo's out there) and the very tip is blunt not sharp. If the tip is too sharp, the point will bottom out in the screw and the sides that do all the work, won't be able to fully contact the inside of the screw. This screwdriver fits so well that the screws actually stick to it once they are removed. If the screwdriver moves AT ALL when you initially try it in the screw, STOP and find a better one. Also, start with the screws in the center, somehow they seem a little easier until you get the feel for it.


Push down hard and turn counter-clockwise, or push down and rotate 3DS counter-clockwise until screw is loose.

Had the exact same problem, even tried the #000 screw driver too. Stripped the screws due to how tightly they are screwed in there and how easy they strip. I am now unsure what to do from here or if all I can do is give up.

Sean Baldwin, · Reply

I second the one who suggested the Whia 273 PH000x40 screwdriver. I had a terrible time unscrewing these screws, and almost stripped them using a cheaper #000 screwdriver. Also tried a 3/16" flathead and destroyed the screwdriver. I bought the Whia and glad I did. It fit perfectly and did not slip at all. DEFINITELY recommend purchasing this high-quality screwdriver. Cost about $10 but well worth it to avoid the hassle.
