First of all we must remove the tray from the cards.

Remove the two Torx screws (T3) that hold the back shell, and with the help of a tool we will unhook all the edges of the casing.

We extract the seven Phillips screws (PH # 00) that hold the module and with a flat tool we will unhook it.

We disconnected the interconnection flex, the fingerprint reader, the coaxial cable, and we can unhook the auxiliary plate.

Finally we remove the fingerprint reader that we are going to change.
