To start we will remove the card tray with the help of an extraction tool.

We apply heat to the back case, and with the help of a fine tool we will open a small hole through which we will insert a plastic spike, and thus the case will be less likely to be damaged.

We peel off the adhesive that joins the area of the speaker and the battery, and extract the nineteen Phillips screws (PH # 00) that hold the intermediate housing, and with the help of a pick we will unhook all the edges of the housing, but carefully do not cut the flex of the fingerprint reader.

Now we will disconnect the fingerprint reader to work with greater comfort.

To finish, we only have to remove the plastic support that is behind the reader, and unhook it to install the new one that we have in its place.
