The glass face should come off with a little coaxing from a pick.

Gently separate the white touch panel from the e-paper screen. These fall apart easily but are held together by two cables.

Use a spudger to detach the small cable from the white touch panel. This cable is for the microphone and vibration motor.

Use a spudger to detach the second cable. This cable is for the display. The second picture shows it already detached.

Be extremely careful with the display cable. It is attached to the display at an extremely thin glass piece that breaks easily. If the glass breaks, it cannot be repaired.
