Best Solution :

1st step : SOFT RESETTING NOKIA MOBILE
Take backups of ur phone books,calender and others, then simply enter the code
*#7780#

2nd step : HARD RESETTING BY CODE
Just enter the code-
*#7370#
Then it asks for security code enter ur security code whose deafault value is 12345
NOTE:
The battery must be full or the charger has to be connected to the phone so that it does not run out of power and make the phone unusable.
Take backup of the contacts and other important data in MMC .

FLASHING

3rd step :FLASHING : ANOTHER METHOD FOR HARD FULL FORMATTING

This step is known as flashing of phone. Always do this step at last (after 1st 2 steps are over and u are not successfull)

1. Make sure you phone is fully charged. (At minimum 3/4 of bettery should be left)

2. Backup your contacts list and personal files to MMC memory card (if possible).

3. Switch-off your mobile phone.

4. Press and hold these three keys together

-Green dial key,-Star key (*)-Three key (3)

then press the power on/off to swtich on the phone.

Do not let go the three keys until you see the “formatting” screen displayed

5. After a few minutes, the format will be complete. Your mobile will now be at its original factory settings (It will reach the same state as that in when you purchased it).
