Phone reset and IMEI code

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 power key is pressed for 10-15 seconds.

To perform the hardware reset, press and hold the Power key for about 10-15 seconds until a short vibration is felt. The phone should restart by itself.
