Hardware reset
If the phone hardware is jammed, you should first recommend that
the consumer performs a hardware reset. The hardware reset does
not reset the Windows Live ID or remove any consumer data. Because
the consumer cannot remove the battery to reset the phone the
phone has a special electronic circuit which cuts the phone power
when the volume down and power keys are pressed for 10 seconds.
To perform the hardware reset press the Volume down and Power
keys and hold them for 10 seconds. The phone screen will turn black
(phone is off). Then press the Power key to turn on the phone.

procedure erases all consumer data! Always first try to perform a hardware reset.
