To begin with we have removed the card tray.

With the help of a tool that is thin enough we will open a hole to insert a plastic prong so as not to damage the back shell. If necessary we can apply some heat before introducing the first tool to soften the glue.

With tweezers we will remove the plastic cover that covers the connector of the fingerprint reader, and with the help of a flat tool we will disconnect the damaged fingerprint reader.
