We remove the battery shield.

We disconnect all the components that are connected on the motherboard.

We take off the side buttons of the phone's chassis, remove the three Phillips screws (PH # 00) that hold the motherboard, take off the headset, and with the help of a flat opening tool, we can remove the motherboard with the components.

We desolder the headset and the vibrator of the motherboard that we have to replace.

We disconnect and remove the front camera.
