To begin, we will unhook the straps, in order to work with greater comfort.

We remove the four Torx screws (T3) that hold the case, and with the help of a flat tool we will unhook it, taking care with the flex that connects it to the motherboard.

We disconnect the battery to work with greater safety.

We peel off the adhesive that is above the shield, remove the Phillips screw (PH # 000) that holds it, and with the help of some tweezers we will unhook it, and we will be able to disconnect the flex with components that joins the back cover to the plate base.

We extract the Phillips screw (PH # 000) that holds the shield that covers the screen connectors, we disconnect the components that are connected to the motherboard.

We extract the two Phillips screws (PH # 00) that hold the motherboard, and with the help of a flat-tipped tool we will lift it.

To finish, we only have to take off the flex from the side buttons of the motherboard that we have to replace.
