To start we remove the card reader with a SIM removal tool.

We will apply heat to the back shell with a thermal mat (about 75ºC for about 5-7 min approx) to soften the adhesive that holds it, and with the help of a tool thin enough we will make a hole to insert one or more plastic spikes and This way we will not risk damaging the case.

We remove the two Phillips screws (PH # 00) that hold the shield, remove it, then disconnect the connector from the fingerprint reader and remove the rear cover along with the reader.

We remove the sixteen Phillips screws (PH # 00) that hold the intermediate casing and with the help of a fine plastic tool we unhook it and remove it.

Carefully remove the intermediate housing as the NFC Antenna is attached to an adhesive that is attached to the motherboard.

We disconnect the battery to work with greater security.

Finally, with the help of an opening tool we pry up and take off and remove the battery.

We can moisten the tool in alcohol so that it is easier for us to take off the battery.
