HARDWARE RESET A NOKIA LUMIA 920

Hardware reset

If the phone hardware is jammed,

we can  performs a hardware reset. The hardware reset does

not reset the Windows Live ID or remove any of your  data. Because

the user  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 5 seconds.

To perform the hardware reset press the Volume down and Power

keys and hold them for 5 seconds. The phone screen will turn black

(phone is off). Then press the Power key to turn on the phone.

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!

Follow next steps to perform OS reset with phone keys.

  

Step 1

 

Make sure the phone is turned Off.

Press and hold the Volume down

and Power keys until an 

exclamation mark is shown on the screen

Step 2

Input the following key combination:

 

1. Volume up

2. Volume down

3. Power

4. Volume down

Step 3

The phone will reset and boot up

automatically
