We will start by removing the four Torx T4 screws that hold the rear case.

After removing the screws we will have to take off the vibrator, which is glued to the plate and the back shell, before removing it.

First we will remove the insulating rubber to avoid losing it or damaging it.

Afterwards we will disengage the inner casing, very carefully since this is very weak.

To remove the flex, simply disconnect it from the base plate and detach it from the inner shell.
