If you want to reset the phone to its factory defaults then please type *#7780# followed by 12345 as the default pin. Please be aware that your data will be deleted among any other settings, applications or customization. After this process, please restart your phone for the new settings to take effect.
``1) Remove the battery, and then wait for about 20 min or so before putting it back
2) Press and hold these three keys together -Green dial key, Star key[*], Three key

4) Do not let go the three keys until you see the WELCOME screen displayed and just let it complete the boot process
