To start we must apply heat to the back shell, in order to soften the adhesive that holds it, and with the help of a thin enough metal tool, we will open a small one through which we will introduce a plastic spike, with which it will be less likely damage the case, and we will take off all the edges.

We disconnect and remove the front camera.

We disconnect and remove the fingerprint reader.

We disconnect all the connectors from the rear cameras, and once disconnected we can remove the module.

We disconnect the flex from the screen, the flex bridge with the charging connector, and the coaxial cable, remove the Phillips screw (PH # 00) that holds the motherboard to the chassis, and with the help of a flat tool we will remove it.

We take off the faulty buttons that we are going to replace with the help of tweezers and a fine tool.
