It is a well known fact that most of the usual problems can be healed by a soft reset of your phone. But some rare problems are only cured by a more intense - hard - reset. Hard reset erases all your data, and returns like a freshly bought phone! These instructions are based on Lumia 720, but it is tested on 520 and 822 too and it might also work on other Lumia devices!
WARNING : BACKUP IMPORTANT DATA BECAUSE YOU ARE GOING TO LOSE THEM IN THIS PROCESS
There are two methods for this process : ONE requires access to your settings and TWO does not. This is because that in some cases you cannot even access your mobile phone UI. But both basically does the same thing.
METHOD ONE ~~~~~~~~~~~~~ IF YOU HAVE ACCESS TO THE SYSTEM SETTINGS

Follow the instructions on scren and that's it! The device will reboot and the phone will be reset!
WARNING: THIS PROCESS MAY TAKE A FEW MINUTES (EVEN AS LONG AS 10)
METHOD TWO ~~~~~ IF YOU DO NOT HAVE ACCESS TO THE SYSTEM SETTINGS
- Power off your phone by holding Power button and volume down for at least 10 seconds.
- Now just hold the power button until you feel ONE vibration, and then hold the volume down. Now you will see a screen with an exclamation mark on it (!)
- Next, you will have to click each of these buttons, in the exact same order:
1. VOLUME UP
2. VOLUME DOWN
3. POWER BUTTON
4. VOLUME DOWN
Now the reset process will begin. DO NOT click any other buttons during the process. After a few minutes, (as mentioned, as long as 10), you will have a completely reset Lumia Device on your hand!
