Remove the eight Phillips screws (PH # 00) that hold the housing and remove the adhesive that is above the battery.

We disconnect the flexes that are connected to the motherboard.

We disconnect and remove the front camera.

We disconnect and take off the audio connector.

We remove the rubber that is stuck to the handset, and with the help of a fine enough prong we take off the handset that we are going to change.
