Guide with all the necessary steps so that you can change the components of the Alcatel A3 (5046D) yourself.
To begin with, with the help of a flat tool we will unhook all the edges of the back shell.
We remove the fourteen Phillips screws (PH # 00) that hold the intermediate housing, and to unhook it we will use the same tool that we used in the previous step.
We disconnect and remove the fingerprint reader that we are going to replace.
