To begin we must apply heat to the back cover to soften the adhesive that holds it, we have used a thermal mat for about 3 minutes, at about 70º C, and then with the help of some plastic spikes we have been taking off all the edges of the casing.

We remove the ten Phillips screws (PH # 00) that hold the casing, and with the help of a flat tool we will unhook it.

We disconnect the battery to work with greater safety.

We extract the five Phillips screws (PH # 00) that we indicated in the first photograph, and with the help of a fine tool we will unhook the lower shield.

We disconnect all the components that are connected to the auxiliary board and remove the card tray.

We raise and remove the auxiliary plate so that it bothers us as little as possible, if you want you can disconnect it.

We disengage the connector from its cabin.

We take off the speaker with a fine metal spike, and we must unhook the plate with antenna contacts that is hooked to the speaker that we are going to change on the back.

To finish, with the help of a spatula or tweezers, we will take off the faulty fingerprint reader that we have to replace.
