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.
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.
Step 14

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. Damaging the socket or cable will result in a 3DS that will blink its power LED when you press the power button - and do nothing else.
Disconnect the speaker assembly ribbon cable with a pair of tweezers.
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.
When reassembling, note that the gold contacts face toward the motherboard (as opposed to the camera cable's gold contacts facing away).
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.
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.
Step 20
Remove the motherboard assembly from the rest of the device.
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.
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.
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.
Continue prying the remaining sides of the front panel by sliding the plastic opening tool down each edge.
Too little heat will result in excessive bending/breaking of the front panel, and too much will melt and destroy the LCD underneath. Take your time.
Step 25
With all of the sides free, lift the upper display front panel off the display bezel.
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.
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.
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.
Step 29
Push the hinge towards the center of the upper case. This will require a fair amount of force.
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.
Step 30
Slowly pull the upper display assembly away from the upper case.
Before proceeding, note how the 3 ribbon cables are oriented (what direction the gold contacts face) and layered together (which cable is on top of which). The cables are too short to reach if they are threaded through in any other orientation.
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.
Step 31 Speaker Assembly
You must gently coil the ribbon cables (similar to an ice-cream cone) to allow them to fit - the cables are wider than the hole.
Carefully feed the speaker assembly ribbon cable through the hole in the upper display bezel.
