First of all we must apply heat to the casing to soften the adhesive that holds it, and with the help of a fine enough tool we will open a small hole through which we will introduce one or more plastic spikes, with which we will take off all the edges of the housing.

We disconnect and detach the NFC antenna module and wireless charging.

We remove the five Phillips screws (PH # 00) that hold the shield, and once removed we can disconnect the battery to work with greater security.

We extract the five screws that hold the speaker, and with the help of a flat tool we unhook it.

We disconnect the flex from the screen, and the two bridge flex that join the auxiliary plate and the motherboard.

And finally we can take off the battery, for this we will use a flat tool which we can moisten a little with alcohol, and thus we will soften the adhesive that holds the battery that we have to replace.
