Disassembly/Repair of the mobile device LG G4 Stylus H635 with each step description and the required set of tools.

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

Pull the stylus pen out.

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.

Carefully remove the battery. 

ℹ️ The LG G4 Stylus H635 model has a battery BL-51YF with 3000 mAh capacity (aka rechargeable battery).

Using a screwdriver (Phillips 1.5 mm PH000), unscrew 11 screws.

Remove the cover with antennas and a loudspeaker. Try to lift the cover by the edges and not push anything between them to not accidentally touch or short-circuit anything on the PCB.

⚠ It is crucial while reassembling, checking the spring contacts on the board, and the contact pads on the cover match and touch. Otherwise, signal loss or signal may be quite weak.

Disconnect the connectors, remove front (selfie) and rear cameras.

Disconnect the display module connector.

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.

ℹ️ In the display frame remained: the earpiece speaker, headphone jack socket, and vibration motor.
