⚠️ Before disassembling, do not forget to turn your phone off.
Disassembly of the mobile device LEAGOO M13 with each step description and the required set of tools.
Step 2. Open the back cover
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.
Step 3. Remove the battery
The battery has unobstructed access, so pry carefully and remove it.
ℹ️️ The Leagoo M13 model has a battery BT6009 with 3000 mAh capacity (aka rechargeable battery).
Step 5. Open the cover
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.
Step 6. Unscrew the screws
Using a screwdriver (Phillips 1.5 mm PH000), unscrew 5 screws.
ℹ️️ 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 part. 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.
Step 7. Open the cover
Open the cover, the loudspeaker assembly with antennas, and turn it over.
⚠️ The loudspeaker is connected with the sub-board by wires.
Step 8. Unsolder loudspeaker wires
Carefully fasten the loudspeaker assembly to freeing the sub-board surface. Unsolder the loudspeaker wires.
Step 10. Unscrew the screws
Using a screwdriver (Phillips 1.5 mm PH000), unscrew 2 screws securing the sub-board.
Step 11. Disconnect the connectors
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).
Step 12. Remove the daughterboard
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.
ℹ️️ 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.
Step 15. Unscrew the screws
Using a screwdriver (Phillips 1.5 mm PH000), unscrew 2 screws securing the motherboard.
Step 16. Disconnect the connectors
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.
Step 17. Remove the mainboard
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.
