To begin we must apply heat to the back cover, and with the help of one or more plastic spikes we will take off all the edges of the back cover.

With the help of the extraction tool we remove the card tray.

We remove the sixteen Phillips screws (PH # 00) that hold the intermediate casing, and with the help of a plastic pick we will unhook it.

We disconnect the battery to work with greater safety.

Finally, we only have to take off the headset that we have to change.
