Unscrew the two Phillips screws securing the battery cover to the lower case.

The screws remain captive to the battery cover.

Grasp the battery cover and lift out of the lower case.

Wedge the edge of an opening tool in between the top of the battery and its lower case housing and pry upwards to dislodge the battery.

Grasp the battery and remove it from the DSi.

Two screws are hidden underneath two rubber feet highlighted in red.

Use the tip of a spudger to pry the rubber foot out of the lower case.

In the same manner, remove the remaining foot off the lower case.

Remove the following screws securing the lower case to the body of the DSi:

• Six 5.2 mm Phillips screws.
• One 2.7 mm Phillips screw.

Insert the flat end of a spudger in between the lower case and lower front panel near the top right corner of the DSi.

Carefully run the spudger along the right edge of the DSi, creating an opening in the process.

Continue running the spudger along the backside of the DSi until the majority of the lower case has been separated from the lower front panel.

Cautiously lift the lower case from its bottom edge.

The lower case is still attached to the motherboard by the volume and SD board cable highlighted in red. Do not try to completely remove the lower case of the DSi yet.

Pry the volume and SD board cable up from its socket on the motherboard with the flat edge of a spudger.

Remove the lower case assembly from the DSi.

Pull the Wi-Fi board away from the motherboard by its edge closest to the headphone jack.

Pry the Wi-Fi antenna connector straight up from its socket on the Wi-Fi board.

Use the tip of a spudger to pry the power board connector out of its socket on the motherboard.

Use your fingernail or the edge of a plastic opening tool to flip up the retaining flap on the following three ZIF sockets:

• Lower touchscreen cable
• Lower LCD cable
• Power board cable

Be sure you are prying up on the hinged retaining flaps, not the sockets themselves.

After flipping up the locking tabs on all three sockets, use your fingers or a pair of tweezers to gently pull the cables straight out of their sockets.

Use your fingernail or the edge of a plastic opening tool to carefully flip up the touchscreen ribbon cable retaining flap.

Make sure you are flipping up the retaining flap, not the socket itself.

Use the tip of a spudger to pull the touchscreen ribbon cable straight out of its socket.

Use your fingernail or the edge of a plastic opening tool to carefully flip up the dual camera ribbon cable retaining flap.

Make sure you are flipping up the retaining flap, not the socket itself.

Use the tip of a spudger to pull the dual camera ribbon cable straight out of its socket.

With the tip of a spudger, Pry the microphone antenna up off its socket on the motherboard.

Remove the following four Phillips screws securing the motherboard to the DSi framework.

• Three longer screws.
• One short screw.

Pull the microphone and Wi-Fi antenna cables out of the notch cut into the motherboard near the headphone jack.

Slightly lift the motherboard upwards to reveal the upper LCD ribbon cable above the ABXY buttons .

Use your fingernail or the edge of a plastic opening tool to carefully flip up the upper LCD ribbon cable retaining flap.

Make sure you are flipping up the retaining flap, not the socket itself.

Remove the motherboard from the DSi.

Use the tip of a spudger to pry the metal backing of the lower LCD up from the DSi's framework.

Lift the lower LCD assembly out of the DSi.

Use a pushpin to remove the four plastic screw covers (highlighted in red) on the front bezel.

Remove the four Phillips screws securing the rear bezel to the front bezel.

Using two hands, gently slide the rear bezel upwards.

The rear bezel will move only about 2 mm.

Slightly close the case of the DSi and lift the rear bezel straight up out of the DSi.

Continue de-routing the microphone and Wi-Fi antenna cables through the opening located on the bottom DSi's framework.

Remove the five Phillips screws securing the power board to the DSi's framework.

Lift and remove the power board from the DSi.

Push the metal hinge pin inward on the D-pad side of the front lower panel with the tip of a spudger.

The pin should move about 3 mm and stop. It is not necessary to try to completely remove the pin.

Slightly detach the lower and upper halves of the DSi.

Do not completely separate both halves yet. There are several ribbon cables that remain threaded through both panels.

De-route the upper LCD and dual camera ribbon cables through the slit near the ABXY side of the front lower panel.

Separate the lower and upper halves from each other.

Using your fingers, grasp the microphone cable and de-route it through the hinge.

The microphone will likely pop out of its housing, so it is probably easier to completely remove it at this point.

De-route the Wi-Fi cable through the hinge.

Tightly coil the display and dual camera ribbon cables enough to push them through the steel hinge tube.

Remove the steel hinge tube.

Carefully push both coiled ribbon cables through the tube molded into the front upper panel.

Pry the front-facing camera straight up out of its housing in the front bezel.

Lift the rear-facing out of its housing in the front bezel.

Remove the dual camera cable assembly from the DSi.

De-route the Wi-Fi antenna cable from its channel in the front bezel.

Lift the Wi-Fi antenna board straight up and remove it from the DSi.

Use the flat end of a spudger to pry the right speaker straight up and out of its housing in the front upper panel.

Lift the right speaker and set it on top of the upper LCD.

In the same manner as previously described, remove the left speaker.

De-route the left speaker cables from underneath the upper LCD.

Lay the left speaker on top of the upper LCD.

Cautiously wedge the flat end of spudger underneath the upper LCD.

Loosen the adhesive by running the spudger along the perimeter of the upper LCD.

Lift the upper LCD by its upper right corner and remove it from the front upper panel.

Desolder the speakers from the upper LCD by heating up the solder joints with a soldering iron and simultaneously using a pair of tweezers to pull the speaker wires away from the logic board.

If you have never soldered before, we have a guide that makes it easy.
