Edit Step 2  ¶ 

  • Hold the device in one hand and turn it over.

  • Grab the top edge of the back cover with your opposite hand so that the cover does not fall back into place.

Edit Step 4 Lower Case  ¶ 

  • Remove the nine 6.3 mm black Phillips screws from the lower case.

  • Remove the 2.4 mm silver Phillips screw above the game cartridge slot.

Image #1

Edit Step 5  ¶ 

  • Lift the bottom edge of the lower case off the rest of the 3DS.

  • There are still two ribbon cables connecting the mother board to the case, so be sure not to pull the lower case all the way off.

  • Use a plastic opening tool to pry the shoulder button ribbon cables off their sockets on the motherboard.

  • Remove the lower case from the device.

Edit Step 6 Circle Pad Joystick  ¶ 

  • Remove the two 7.7 mm Phillips screws securing the back of the Circle Pad to the motherboard.

Image #1

Edit Step 7  ¶ 

  • Use the flat end of a spudger to pry the back of the Circle Pad off the motherboard.

  • Lift the Circle Pad joystick off the motherboard and lay it on its back so that the ribbon cable connector is accessible.

Image #1

Edit Step 8  ¶ 

  • Use the flat end of a spudger or your fingernail to flip up the retaining flap on the Circle Pad ribbon cable ZIF socket.

  • Be sure you are prying up on the hinged retaining flap, not the socket itself.

  • Lift the Circle Pad joystick off the motherboard.

Image #1

Edit Step 9  ¶ 

  • To decrease the chance of losing it during repairs, you may want to remove the two thin pads underneath the Circle Pad joystick.

  • Use a spudger or screwdriver to lift the pads up and remove them from the device.

Image #1

Edit Step 10 SD Board  ¶ 

  • Remove the two 4.5 mm Phillips screws securing the SD board to the motherboard.

Image #1

Edit Step 11  ¶ 

  • Use the flat end of a spudger to pry the SD board ribbon cable connector off its socket on the motherboard.

Image #1

Edit Step 12  ¶ 

  • Insert the flat end of a spudger between the SD board and the motherboard.

  • Run the spudger along the sides of the SD board to free it from the adhesive pad holding it in place.

  • Once completely freed, lift the SD board straight off the motherboard.

Image #1

Edit Step 13 Wi-Fi Board  ¶ 

  • Slide the flat end of a spudger under the corner of the Wi-Fi board, and lift it away from the motherboard.

  • The Wi-Fi antenna cable is still connected to the Wi-Fi board, so you cannot completely remove the Wi-Fi board yet.

Image #1

Edit Step 14  ¶ 

  • Lift the Wi-Fi board off the motherboard and rotate it so that the bottom side is facing up.

  • Use the flat end of a spudger to pry the Wi-Fi antenna cable connector off its socket on the Wi-Fi board.

Edit Step 15 Motherboard Assembly  ¶ 

  • Grasp the microphone ribbon cable near the microphone with a pair of tweezers.

  • Pull the microphone straight up out of the upper case.

Image #1

Edit Step 16  ¶ 

  • Use the flat end of a spudger or your fingernail to flip up the retaining flap on the speaker assembly ribbon cable ZIF socket.

  • Be sure you are prying up on the hinged retaining flap, not the socket itself.

  • Disconnect the speaker assembly ribbon cable with a pair of tweezers.

Image #1

Edit Step 17  ¶ 

  • Use the flat end of a spudger or your fingernail to flip up the retaining flap on the camera ribbon cable ZIF socket.

  • Be sure you are prying up on the hinged retaining flap, not the socket itself.

Image #1

Edit Step 18  ¶ 

  • Remove seven Phillips screws securing the motherboard to the upper case:

    • Four 2.5 mm gold screws

    • Two 3.5 mm black screws

    • One 2.5 mm silver screw

  • Lift the side of the motherboard that sits along the bottom edge of the 3DS.

Image #1

Edit Step 19  ¶ 

  • Continue lifting the motherboard assembly and rotate it until it is resting next to the rest of the device.

  • Use the flat end of a spudger or your fingernail to flip up the retaining flap on the LCD ribbon cable ZIF socket.

  • Be sure you are prying up on the hinged retaining flap, not the socket itself.

Image #1

Edit Step 20  ¶ 

  • Remove the motherboard assembly from the rest of the device.

Image #1

Edit Step 21 Upper Display Front Panel  ¶ 

  • Before continuing with disassembly, use a pair of tweezers to remove the clear plastic diffuser for the wireless notification LED. The small piece is likely to fall out on its own, and may be difficult to find if it lands on the floor.

Image #1

Edit Step 22  ¶ 

  • De-route the Wi-Fi antenna cable from the bottom of the upper case.

  • This step is not necessary if you are only replacing the front panel; however, the replacement of the upper screen, speakers, cameras, and Wi-Fi antenna require it.

Image #1

Edit Step 23  ¶ 

  • Heat the edges of the upper display front panel with a hair dryer or heat gun to soften the adhesive holding it to the display bezel.

  • Begin prying the edges of the front panel off with a plastic opening tool.

  • If it is difficult to pry the front panel off, reheat the area you are working on with the heat gun, and then return to prying. Applying excessive force could crack the front panel.

Image #1

Edit Step 24  ¶ 

  • Continue prying the remaining sides of the front panel by sliding the plastic opening tool down each edge.

  • Remember, the time saved by not returning to the heat gun when needed is not worth a broken front panel.

Image #1

Edit Step 25  ¶ 

  • With all of the sides free, lift the upper display front panel off the display bezel.

Image #1

Edit Step 26 Rear Display Bezel  ¶ 

  • Remove the six 3.6 mm Phillips screws securing the rear display bezel to the front display bezel.

Image #1

Edit Step 27  ¶ 

  • Flip the device over so that the rear display bezel is on top and the hinge is on the side opposite from you.

  • Lift the edge of the rear display bezel closest to you and rotate it towards the hinge.

  • Continue to lift the rear display bezel off the rest of the device until it is free.

  • There are clips toward the bottom of the rear display bezel holding it in place. Use enough force to disengage the clips, but be careful not to break them.

Image #1

Edit Step 28 Upper Display Assembly  ¶ 

  • Remove the 3D adjustment switch from the front display bezel.

  • This step is not necessary for disassembly, but the switch is likely to fall out on its own. By removing it yourself, you reduce the chance of losing it.

Image #1

Edit Step 29  ¶ 

  • Insert a metal probe into the space above the ABXY buttons with the point touching the metal hinge.

  • Push the hinge towards the center of the upper case. This will require a fair amount of force.

  • Before and after images of the hinge location when looking at the back of the upper display are shown.

Image #1

Edit Step 30  ¶ 

  • Slowly pull the upper display assembly away from the upper case.

  • Make sure that the various ribbon cables are being fed through the slit in the upper case.

  • Separate the upper display assembly from the upper case.

Image #1

Edit Step 31 Speaker Assembly  ¶ 

  • Carefully feed the speaker assembly ribbon cable through the hole in the upper display bezel.

  • You may have to gently fold the edges of the connector end of the ribbon cable to allow it to fit.

Image #1

Edit Step 32  ¶ 

  • Remove the 2.5 mm Phillips screw securing the right speaker board to the upper display bezel.

Image #1

Edit Step 33  ¶ 

  • Use the flat end of a spudger or your fingernail to flip up the retaining flaps on the parallax barrier ribbon cable ZIF sockets.

  • Be sure you are prying up on the hinged retaining flap, not the socket itself.

  • Use a pair of metal tweezers to disconnect the two ribbon cables.

Image #1

Edit Step 34  ¶ 

  • Use the flat end of a spudger to pry the left and right speakers out of their places in the upper display bezel.

  • Pry the camera status LED out of the upper display bezel with the tip of a spudger.

Image #1

Edit Step 35  ¶ 

  • Remove the speaker assembly from the rest of the display assembly.

Image #1

Edit Step 36 Cameras  ¶ 

  • Gently roll the upper LCD ribbon cable and camera ribbon cable together and insert them into the hinge opening.

Image #1

Edit Step 37  ¶ 

  • Use a pair of metal tweezers to remove the black metal hinge ring from the upper display bezel.

  • Carefully pull the camera and upper LCD ribbon cables through their hole in the upper display bezel.

Image #1

Edit Step 38  ¶ 

  • Peel the camera ribbon cable off the back of the upper LCD.

  • The ribbon cable is held to the back of the LCD housing by an adhesive, so pull on it gently to avoid tearing the ribbon cable.

  • Remove the camera ribbon cable assembly.

Image #1

Edit Step 39 Upper LCD  ¶ 

  • Use your thumbs to push the upper LCD from the front out of the upper display bezel.

  • Remove the upper LCD.

Edit Step 40 Wi-Fi Antenna  ¶ 

  • Pull the Wi-Fi antenna cable through its hole in the upper display bezel.

  • De-route the Wi-Fi antenna cable from the upper display bezel.

Comments Comments are onturn off

this guide is idiotic, i followed it to the letter and all it did was make me realize that there is a much easier and much safer way of replacing the antenna; steps 1-29 (step 30 if you want to, not necessary though) are fine and right on the money, however pushing the ribbons through makes it way more difficult when you could just remove the antenna board, thred just the wire through leaving the ribbons unchanched, and put in the replacement board and thread the wire through, then reassemble the console. this method almost guarantees that the ribbons wont get scratch and you wont get frustrated.

#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.

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 xavierfflores@gmail.com
