Disassembly/Repair of the mobile device LG K3 K100 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.

Carefully remove the battery.

ℹ️️ The LG K3 K100 model has a battery BL-49JH with 1940 mAh capacity (aka rechargeable battery).

Remove the cover with antennas.

Pry up the connectors of the display and touchscreen.

We recommend using a special heating device such as a separator machine, heat gun, or heating mat. It will simplify the process. You can use a home hairdryer, but you will have to make a nozzle by hand or have a suitable one in the kit to gently heat and concentrate the heat flow in the right place.

ℹ️️ The surface of the display module must be heated to soften the adhesive underneath. The approximate heating temperature is 50° C / 125° F.

Use a thin plastic film or pick for separation. To facilitate the process, you can use isopropyl alcohol. It is often most difficult to pass the tool between the parts to be divided. Choose the far edge from the FFC cables or buttons.

Do not use a lever or any force for separation that could damage the elements inside.

The process can be seen in our video entirely so as well as in detail, at the end of the instructions.

Open two covers securing the motherboard.

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