Step 2.
Use the Key tool (aka Needle) or Paperclip. Push the tip all the way into the hole until the tray ejects, and then pull the tray out.
â ī¸ Pay attention! The tool must be inserted into a special hole on the edge of the phone's housing. Do not press too hard. It may break the tray eject mechanism.
Step 3.
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.
âšī¸ī¸ The surface of the back cover 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.
Do not let the liquid get inside the smartphone. The process can be seen in our video entirely so as well as in detail, at the end of the instructions.
â ī¸ Look in advance at the picture of the places where the touchscreen and display cables pass under the display module to avoid accidental damage.
Step 4.
Using a screwdriver (Phillips 1.5 mm PH000), unscrew 7 screws.
â ī¸ Try not to touch the camera. The camera is quite fragile!
If you leave prints or other marks on the lens, it will be difficult enough to clean the lens, and the quality of the images may deteriorate.
Step 5.
Remove the cover with an NFC tag and 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.
âšī¸ī¸ On the upper cover, you can see the metalized coating on the plastic in the form of tracks and contact pads. These are Wi-Fi, Bluetooth, and GPS antennas.
â ī¸ It is important 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.
Step 6.
Disconnect the battery connector as soon as possible.
âšī¸ī¸ The LG V30 Plus US998 model has a battery BL-T34 with 3300 mAh capacity (aka rechargeable battery).
â ī¸ It is highly recommended to disconnect the connector to avoid possible short circuits during disassembly.
Also, try not to use a metal tool to disconnect the rechargeable battery connector or do it carefully.
Step 8.
Remove the loudspeaker assembly with antennas.
â ī¸ It is important 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.
Step 9.
Using a screwdriver (Phillips 1.5 mm PH000), unscrew the 2 screws securing the charging port.
Step 10.
Pry up the connectors on the PCB.
â ī¸ 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.
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.
â ī¸ 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.
