Disassembly/Repair of the mobile device LEAGOO M13 with each step description and the required set of tools.

⚠ Before disassembling, do not forget to turn your phone off.

Using a spudger or a plastic pick, carefully, around the edge, detach the back cover clips, and remove it.

Do not insert the tool deeply or bend it. Otherwise, the housing may be tampered with or damaged.

⚠ Be careful when opening the cover from the volume and power buttons side. Thin cable and fragile buttons are straightforward to damage.

⚠ Look in advance in the picture for the cables’ location for inter-board, touchscreen, display, buttons (if any) under the cover to not damage them accidentally.

The battery has unobstructed access, so pry carefully at the end and remove it.

ℹ️ The Leagoo M13 model has a battery BT6009 with 3000 mAh capacity (aka rechargeable battery).

Using a screwdriver (Phillips 1.5 mm PH000), unscrew 12 screws.

Remove the cover with antennas that protect the printed circuit board (PCB). Try to lift the covers by the edges and not push anything between them to not accidentally touch or short-circuit anything on the PCB.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew the five screws.

ℹ️ Be sure to note the location of the screws before disassembling. When assembling the device, screwing the screw in the wrong place may damage the device or its parts. To avoid damage, the removed screws and individual pieces (as gaskets or brackets) must be laid out in the appropriate order, or the screws and their holes in the phone must be marked with colored markers.

Open the cover, the loudspeaker assembly with antennas, and turn it over.

⚠ The loudspeaker is connected with the sub-board by wires.

Carefully fasten the loudspeaker assembly to freeing the sub-board surface. Unsolder the loudspeaker wires.

Remove the microphone cover.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew the two screws securing the sub-board.

Disconnect the coaxial cable connector and inter-board sub-screen cable on the daughterboard.

⚠ Do not pull on the cable or pry it with a sharp tool, the connectors are pretty weak and break easily, or the cable falls out of the end (lug).

Remove the sub-board. It is glued to the frame with metalized tape, so to facilitate the process, the board can be heated a bit.

ℹ️ The board contains a charging port (Micro USB), microphone, vibration motor, spring contacts for the speaker, and an antenna unit.

⚠ It is not necessary to insert the tool under the board when removing the sub-board. Internal components could be damaged.

Pry up the connector and remove the fingerprint sensor.

Pry up the connectors and remove the rear camera.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew the two screws securing the motherboard.

Release the connectors of the power volume buttons cable, disconnect the display module cable connector, and coaxial cable connector.

⚠ Be careful when removing the cables from the connectors, the cables are pretty thin, and it is easy enough to break them or damage the contact tracks inside.

Carefully remove the printed circuit board. There is no need to use a lever or try to reach the board by force. Make sure that nothing is getting in the way or holding the board.

⚠ Do not bend the circuit board when removing it or push tools under it. Unbeknownst to yourself, you can damage components or cables from the inside.

Pry up the connector and remove the proximity sensor.

Disconnect the connector and remove the front (selfie) camera.

Pry up the connector and remove the rear camera.
