Remove a damaged back casing.
Place the phone on a flat surface that the back is facing you. Remove the back panel by placing your thumb on the LG logo and sliding the panel across the length of the phone until it is removed.
Once the panel is removed, you are looking directly at the battery. It is the black rectangle in the middle of the phone. You can remove the battery by sliding a finger into the notch where the LG logo was on the panel and lifting up the battery.
Remove the battery completely from the phone.
Before continuing pull off all the rubber tabs to the headphones, and the power input.
Now turn the phone so that you can see the back where the battery was. Using a screw driver, unscrew the 6 screws holding the back casing together.
At the top of the logic board there is a small rectangle with a white pad on it, use your tweezers and gently grip the neck of the orange wire.
Gently pull up on the orange wire until it comes loose. It may take some force so do not be concerned with being overly gentle.
