To begin we will apply a little heat to the back cover to soften the adhesive that holds it, and helping us with a thin metal spike we will make some egg to introduce a plastic to go unpinning all the edges of the casing.

We extract the eleven Phillips screws (PH # 00) that hold the antenna module with loudspeaker and the intermediate housing, and with the help of a flat tool we will disengage both parts.

We disconnected the battery to avoid possible damage.

We removed the front camera.

We disconnect all the components that are connected to the motherboard, and remove the tray from the cards.

Finally, with the help of a pair of flat tongs, we will take off the faulty button.
