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 to work with greater safety.

We extract the five Phillips screws (PH # 00) that we indicated in the first photograph, and with the help of a fine tool we will unhook the lower shield.

We disconnect all the components that are connected to the auxiliary board and remove the card tray.

We raise and remove the auxiliary plate so that it bothers us as little as possible, if you want you can disconnect it.

We disengage the connector from its cabin.

We take off the battery and the adhesive that surrounds it, since the charging flex is below the adhesive.

Finally, we will disconnect the charging flex from the motherboard and take it off completely, and we will be able to install the new flex that we have in its place.
