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 10-15 seconds.
To perform the hardware reset, press and hold the Volume down and
Power keys at the same time for about 10-15 seconds until a short
vibration is felt. The phone should restart by itself.
Software / operating system (OS) reset
The software / operating system (OS) reset returns the phone to its out-of-the-box state. Note that this
procedure erases all consumer data! Always first try to perform a hardware reset.
