DISASSEMBLING PROCEDURE

How to remove Loud Speaker
Locate and remove the twelve small Phillips screws (#00) that secure the loud speaker and rear housing/protective cover to the motherboard (marked with orange circles).
With the small Phillips screws removed you can now pry up and remove the loud speaker as well as the rear housing/protective cover over the motherboard.
How to removePower & Volume Button Assembly

How to remove Front-Facing Camera
Release the front-facing camera’s flex cable connection from the motherboard. You can now pry up and remove the front-facing camera from the LG G2.
How to remove Dock Connector & Headphone Jack Assembly
Locate the two coaxial cable plugs. Use the tweezers to pry up and release the two plugs from their connectors (marked with orange circles).
Locate the five wafer plug connectors. Use the tweezers or the nylon spudger to release the five plugs from their connectors (marked with white rectangles).
There is an extended portion of the G2 dock connector assembly located on either side of the battery. Use the nylon spudger to peel up the extended portion of the assembly from the adhesive holding it in place.
The bottom portion of the dock connector & head phone jack assembly also has adhesive holding it in place. Use the nylon spudger to pry up and remove the dock connector assembly from the LG G2.
Be mindful of the microphone ribbon cable that is secured by a rubber grommet in its housing (marked with orange arrow).
How to remove Battery & Motherboard
Release the battery’s connection. The battery is secured in place with adhesive, use the nylon spudger to pry up and remove the battery from the LG VS980.
Next, locate the two wafer plug connectors. Use the spudger to detach the two plugs from their connectors (marked with white rectangles). This will free the motherboard from the LG G2.
Now, maneuver the motherboard up and out of the G2 smartphone.
How to remove Rear-Facing Camera
Use the fine tip curved tweezers to pry up and remove the rear-facing camera from the LG G2. Be careful as it is secured in place with a small amount of adhesive.
How to remove Earpiece Speaker Assembly
The earpiece speaker is secured in its housing with adhesive. Use the fine tip curved tweezers to pry up and remove the earpiece speaker from the G2. The sensor flex cable is also secured in its housing with adhesive. Use the fine tip curved tweezers to pry up and remove the sensor flex cable from the LG G2.
How to remove Display Assembly (LCD & Touch Screen)
The display assembly (LCD & touch screen) are fused together and secured to the frame /front housing of the LG VS980 using a good amount of adhesive. It will require heat, and patience, to separate the display assembly from the frame.
This procedure is only recommended on a G2 with a DAMAGED display that requires replacement. Use the heat gun or blow drier to heat the adhesive securing the display assembly (LCD & digitizer) to the G2’s frame/ front housing. The heat will loosen the adhesive securing the parts together.
To separate the display assembly from the frame/front housing, utilize one of the screwdrivers and through the front-facing camera hole, while securely gripping the sides of the G2 frame, carefully push the damaged display assembly away from the LG G2’s frame.
You can now use the plastic opening tool to continue working around the entire G2 display assembly slowly separating it from the frame/front housing.
