We will start by removing the back cover. For this we will use a plastic opening tool, to avoid scratches, introducing it between the back shell and the frame.

Now, to remove the back cover, we will have to locate and remove the eight Phillips screws (PH # 00) that hold it.

Once the screws are removed, with the help of a tine we will separate the frame housing.

To remove the buttons, we will only have to disconnect them from the base plate and detach them from the frame.
