Main Board Disconnect

Unplug all cables and fully power off your device.

Working on your device requires laying it screen-side down. To prevent damage, lay it on a soft surface such as a towel.

If you have an SD card installed, remove it.

Use a T6 Torx screwdriver to remove the four 13.4 mm‑long screws securing the battery shell.

Lift the bottom edge of the battery shell to unhook its tabs.

Remove the battery shell.

Use blunt nose tweezers to pull the battery connector out of its socket on the bottom right corner of your device.

Lift one of the battery's short edges until the clips release.

Remove the battery.

Use the point of a spudger to push the clip out and release the board.

Swing the bottom edge of the button board up and over the cartridge reader.

Set the board on top of the cartridge reader so the cable's connector is facing the bottom of the device.

Put the top edges of the board under their tabs on the rear shell.

Lay the board onto the rear shell so the alignment posts go into their circular cutouts on the board.

Press the board down until the plastic clip engages.

Use the tip of a spudger or a clean fingernail to flip up the hinged locking flap on the board cable ZIF connector located on the board itself.

Use blunt nose tweezers to pull the cable straight out of its socket.

Remove the board.

Firmly grip your device with one hand.

With your free hand, lift the bottom edge of the rear shell until it clears the front shell.

Pull the rear shell down until the sliding tabs disengage.

Remove the rear shell.

Thread the button board cable through its slot in the rear shell.

Lay the rear shell on the front shell so its bottom edge slightly overhangs.

Push the rear shell in and slide it up to engage the sliding tabs.

Use the tip of a spudger or a clean fingernail to flip up the hinged locking flap on the right speaker cable ZIF connector.

Use blunt nose tweezers to pull the cable straight out of its socket.

Repeat the process to disconnect the left speaker and power/volume button cables from their ZIF connectors.

Use a T6 Torx screwdriver to remove the 7.4 mm‑long screw securing the main board.

Grip the outer edges of the cartridge reader and gently lift the bottom edge of the main board until you can access the screen cable.

Keep the main board raised for the next step.

Insert the flat end of a spudger under the top right corner of the screen cable press connector.

Twist the spudger to disconnect the screen cable.
