We will start by removing the back cover. For this we will have to heat it to about 60ºC for about a minute to soften the adhesive.

With the hot lid, we will slide a flat tool between it and the frame around the contour, to take it off.

Remove the ten Phillips screws (PH # 00) that hold the intermediate housing and the speaker module and disengage them.

We disconnect the battery from the motherboard and heat the device to soften the battery adhesive a bit. We introduce a flat and flexible tool under the battery to take it off.
