First of all, we have removed the card tray.

We apply heat to the case, and with the help of an opening tool we will take off all the edges of the case.

We extract the eighteen Phillips screws (PH # 00) that hold the intermediate housing, and with the help of a flat tool we will unhook all the edges.

We disconnected the battery to work with greater security, and the fingerprint reader to work with greater comfort.

We disconnect and remove the front camera.

We disconnect and remove the rear cameras.

We disconnect the coaxial cables, the interconnection flex and the screen.

We extract the Phillips screw (PH # 00) that holds the motherboard, and with the help of a flat tool we will lift it carefully.

We take off the battery being careful not to damage it too much, and we take off the adhesive that surrounds it.

Finally we will take off the damaged volume pushbutton flex, for this we will take off the adhesive that covers a part, and we will be able to take it off completely.
