To start we remove the card reader with an extraction tool.

To remove the back cover we open a small hole with an opening tool and carefully unhook all the edges.

With the help of an antistatic clamp, we remove the adhesive that protects the connector, lift the tab of the connector and remove the flex from the fingerprint reader.

Finally, we lift the adhesive from the back cover as indicated in the first image and with a fine tool we take off the fingerprint reader and remove it.
