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.

We take off the edges of the adhesive, we introduce a few drops of isopropyl alcohol, we slightly tilt the phone so that the alcohol flows under the battery and affects the more adhesive the better, and taking advantage of the adhesive strips that the adhesive has, we will take off the battery that we have what to replace
