DISASSEMBLING PROCEDURE 
Insert the plastic opening tool or spudger in the notch that is located on the side of the LG handset. Carefully work your way around the entire smartphone, gently freeing the locking clips.
You can now remove the battery door/cover from the LG G3.
Next, utilize the plastic opening tool or spudger to pry the battery up and out of its secured location.
How to remove Loudspeaker
Locate and remove the thirteen small Phillips screws (#00) that secure the rear housing/frame and loudspeaker to the smartphone (marked with orange circles).
Then slide the SIM and Micro-SD cards out of their trays (marked with an orange arrow).
Insert the plastic opening tool in the seam of the smartphone to create separation between the loudspeaker and the phone. You can now carefully remove the loudspeaker from
the LG G3.
Next, use the pry tool or spudger to separate the rear housing/frame from the smartphone’s display assembly. Work your way around the perimeter of the handset until all of the clips have been released and the rear housing/frame is removed from the G3.
How to remove Power & Volume Buttons
Utilize the heat gun or a blow dryer to soften the adhesive securing the power and volume button assembly to the rear housing/frame.
Now, use the fine-tip curved tweezers to gently pry the power and volume button assembly up from the adhesive and remove it from the LG handset.
How to remove Motherboard
Locate the four wafer connections (marked with orange rectangles). Use the fine-tip curved tweezers to release the connections from their sockets.
You can now carefully maneuver the motherboard out of the LG G3.
How to remove Front-Facing Camera
The front-facing camera is located in the top corner of the LG G3. Use the fine-tip curved tweezers to lift the camera out of its housing and remove it from the LG handset.
The rear-facing camera is located toward the top of the handset and is secured in place with a small amount of adhesive.
Utilize the heat gun or a blow dryer to soften the adhesive, and then use the fine-tip curved tweezers to lift the camera out of its housing and remove it from the G3.

How to remove Display Assembly (LCD & Touch Screen Digitizer)
The LCD & touch screen/front panel on the LG G3 are fused together and cannot be separated from the frame/bezel of the smartphone without the use of heat and patience. Separating the display assembly from the frame is only recommended if the G3 has a CRACKED or DAMAGED screen that needs to be replaced.
Use the heat gun or a blow drier to soften the adhesive securing the display assembly to the frame/bezel of the LG G3.
To separate the display assembly from the frame/front housing, utilize one of the screwdrivers, and through the front-facing camera hole carefully push the damaged display assembly away from the LG G3’s frame.
You can now use the plastic opening tool or nylon spudger to continue working around the entire G3 display assembly slowly separating it from the frame/front housing.
