Introduction

What you need

Step 1

              Battery               
  • Ensure your device is powered off before proceeding. Failure to do so may result in electrical shock or damage to the device.
  • Place the 3DS upside down. Remove the game card, headphones, charging cable, stylus, or anything else that may be connected to the device.

Step 2

  • Using a JIS #0 screwdriver, loosen the two black screws on the back.
  • The screws are held in place by captive washers and should not be completely removed.

Step 7

  • To separate the cover, carefully lift it up and away from the hinges (in order to clear the headphone port), then pivot it towards the hinges to expose the circuit boards.
  • Don’t fully remove the cover yet, or you may damage the delicate ribbon cable that still connects it to the motherboard.

  • Locate the gold terminal plug with a red cable at the top left of the motherboard. Using your fingers, carefully pull the plug straight upward to remove.
  • Use a pair of tweezers to disconnect the single ribbon connector.
  • Don’t do what we did – be very careful not to pull on the red cable.

Step 13

  • Using tweezers, gently pull the five marked ribbons out of the ZIF connectors along the sides of the motherboard.
  • These ZIF connectors are held in place by friction and do not have locks—lifting the flaps on these connectors will break them! Note that in some models the upper-most connector may have a lock.
  • Three of the ribbon connectors have plastic clamping flaps that cover the ribbon to prevent slippage. Use the tweezers to flip them up before ribbon removal.
  • When reassembling the device, be sure to flip the ZIF clamps back down.
  • While the SD card reader is shown as removed in this photo, it is optional for the removal of the motherboard.

Step 15

  • Carefully pivot the motherboard 90 degrees toward the hinges to reveal two more ZIF connectors on the underside of the motherboard.
  • Both have latches that must be flipped up. The left, longer latch is black; the right, shorter one is white. Flip up the flaps, slide the ribbons out and remove the motherboard.
  • Note which way the ribbons slide into their connectors carefully, as they are different.

Could someone point out where the fuses in the motherboard are hidden?

BabblingFishes - Feb 11, 2016

With some digging, I managed to find this on the GBAtemp forums , which host a community of 3DS modders:

https://gbatemp.net/threads/screwed-up-p

Seems like no one’s quite sure, but it could be a start. Unfortunately, the N3DS components are largely small black boxes with no labeling.

If you have a multimeter, it might help to test some of these mystery boxes.

Question: Seeing as how you pulled the red cable in the photos, how was that fixed? Asking for a friend.

BabblingFishes - Feb 17, 2017

We…never fixed that actually, as we didn’t have the tools for it and the device had been loaned to us specifically for tearing down.

I don’t know if iFixit themselves ever did anything with it, but I would imagine soldering the frayed end of the cable back onto the plug would work. (Here’s a guide on that: http://www.instructables.com/id/Solderin… )
