To begin with we will have to remove the tray from the cards before removing the back cover.

We remove the two Pentalobe 0.8 screws (TS1), and with the help of a plastic tine we uncouple all the edges of the casing.

Remove the six Phillips screws (PH # 00) that hold the speaker and we can unhook it.

Disconnect the coaxial cable, the interconnection flex and the front button with fingerprint reader, then we will extract the Phillips screw (PH # 00) that holds the auxiliary plate that we are going to change, and with the help of a flat tool we will detach it.
