Phone rese

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.

Option 1: About menu

- Use this option if the consumer knows the lock code

- This option warns the consumer about data loss!

-Tap Settings > About > reset your phone

Option 2: Hardware key combination

- Use this option if the phone is locked and the consumer does not know the code

- Note: no warning about data loss!

- Do not advertise this feature to consumers!

Follow next steps to perform OS reset with phone keys.

Step 1

Make sure the phone is turned Off.

1. Press and hold the power key

2. Phone vibrates (release the
power key)

3. Press and hold the volume
down key

4. Exclamation mark is shown on
the screen (release the volume
down key)

Step 2

Input the following key
combination:

1. Volume up

2. Volume down

3. Power

4. Volume down

Step 3
