Remove the fourteen Phillips screws (PH # 00) that hold the upper housing and the antenna module with speaker, disconnect the flex from the battery to work with greater security, and with the help of a flat tool we will unhook them.

We disconnect and remove the front cameras.

We disconnect the flex from the screen, the coaxial cable of the auxiliary plate, we remove the card tray, and we can now lift the motherboard and disconnect the flex from the auxiliary plate from its back.

We disconnect the flex from the audio connector, and with the help of a flat-tip tool we will detach the auxiliary plate.

Remove the Phillips screw (PH # 00) that holds the audio connector and remove it with tweezers.
