We will start by removing the back covers. To do this, we will leverage with an opening tool until they are dislodged.

Remove the screws that hold the casing and disengage.

We disconnect the components of the base plate and remove the adhesives that hold it.

Take off the flash, the side button and the headset.

Remove the SIM / SD tray and lift the plate. Before removing it, we cut the adhesive that holds it.

All that remains is to desolder the sensor on the motherboard.
