To begin we must take off the back cover, for this we must apply heat to the casing to detach it with greater ease, once applied enough heat we will introduce a fine tool and being careful not to damage the paint of the casing we will remove all the edges .

Remove the nine Phillips screws (PH # ? 00) that hold the intermediate housing and disconnect the connector from the fingerprint reader and the coaxial cable.

We disconnect the flex that we are going to change, and with the help of a tool fine enough we will take off the zone of the pulsadores, and we will be able to paste the new one in its place.
