It is possible that the vibration motor & speaker will need to be transferred to the new display. The display that I replaced had the vibration motor and speaker already installed.

Once the mainboard has been removed, use a heat gun to heat up the bottom of the vibration motor (from the screen side). Insert a thin, flat edged tool to pry the vibration motor free.

Now complete these steps in reverse to re-assemble the device.

As mentioned in step 6: To test the device the antenna/loudspeaker cover needs to be attached otherwise an error symbol will appear on the screen.
