To begin, we apply a little heat with a thermal mat to the back cover to soften the adhesive that holds it, and with the help of a thin tool, we will open a small hole through which we will introduce a plastic spike and take off all the edges of the housing. We use a plastic tool as this is less likely to damage the back cover.

Remove the fourteen Phillips screws (PH # 00) that hold the intermediate housing, remove the card tray, and with the help of a plastic spike we will unhook all the edges of the housing.

We disconnect the battery to work with greater security.

We disconnect and remove the flex bridge that is above the battery.

To finish we will take off the battery that we have to replace, for this we have used a tool which we have moistened with alcohol to soften the adhesive that holds it.
