To start we apply heat to the screen to soften the adhesive, and with the help of one or more plastic spikes we will peel off all the edges of the screen.

Once the screen is detached we must remove the Phillips screw (PH # 00) that holds the shield that covers the screen connector, and we can disconnect it.

Remove the twelve Phillips screws (PH # 00) that hold the intermediate housing, and with the help of a thin tool we will lift the housing.

We disconnect the battery to work with greater security.

We disconnect from both ends the flex bridge that is above the battery, and we will also disconnect the flex from the side push-buttons.

And finally we can take off the damaged battery that we need to replace.
