To begin with, we must apply heat to the back cover to soften the adhesive that holds it, we can apply heat several times since the adhesive is quite strong. With a fine tool we will open a small hole through which we will introduce one or more plastic spikes, so as not to damage the paint of the casing, and we will take off the entire edge.

We extract the ten Phillips screws (PH # 00) that hold the intermediate casing, and with a flat-point tool we will unhook it.

We disconnect the battery to work with greater safety.

We extract the six Phillips screws (PH # 00) that hold the lower intermediate casing that covers the auxiliary plate.

We disconnect all the components that are connected to the auxiliary board, and with the help of the extraction tool we will remove the SIM tray.

We lift the auxiliary plate and disconnect the two coaxial cables that are connected to the back of the plate.

We extract the two Phillips screws (PH # 00) that hold the speaker, we take it off with the help of a fine metal tool, and when lifting it we will have to unhook the plate with antenna contacts that is on the other side, and we will be able to place the new speaker in its place.
