Nintendo 3DS IR Board Replacement

Step 1 Back Cover

• 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.
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.
• Flip the 3DS over again so that the back cover is facing up.
• Pull the back cover up and away from the rest of the device to remove it.
Step 3 Battery
• Insert a plastic opening tool into the notch in the lower case above the battery.
• Pry the battery up with the plastic opening tool.
• Grab the top edge of the battery and lift it out of the lower case.
Step 4 Lower Case
• Remove the nine 6.3 mm black Phillips screws from the lower case.
• These screws will strip very easily unless you use the correct size bit. Apply pressure to the screws while turning to avoid stripping them.
• Remove the 2.4 mm silver Phillips screw above the game cartridge slot.
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.
Step 6 IR Board
• Use the flat end of a spudger to lightly pry the IR board off the motherboard.
• Grab the edges of the IR board with two fingers and lift if from the motherboard.
