To begin we must extract the card tray, for this we will use the extraction tool.

With the help of some spikes we will unhook all the edges of the case, but as you can see in the fourth photograph, before completely removing the case we must apply a little heat to the fingerprint reader to be able to detach it from the case.

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

We disconnect the battery to work with greater safety.

We extract the eight Phillips screws (PH # 00) that hold the housing and with a flat-tipped tool we will unhook it.

To detach the speaker from the bottom cover we will use a thin metal pick, now we just have to clean the adhesive residue, place the new speaker and follow these steps in reverse.
