We start by applying heat to the back of the terminal and with the help of a plastic tool we peel off the adhesive around the entire contour until the battery cover is removed.

With a Phillips-type screwdriver (PH # 00) we remove the fifteen screws that hold the intermediate casing, we remove the sim tray and then with a thin plastic tool we release the casing all the way around until it is separated from the screen.

We disconnect the battery with the help of a fine tool to avoid incidents.

In this step we remove the interconnection flex by disconnecting it from both ends once it is loose, we remove it.

Then we apply a little alcohol to soften the adhesive and then with a battery extraction tool we extract it from its housing little by little until we are able to remove it from its housing.
