SOFT RESETTING NOKIA 6600 (for all s60 mobiles)
A Soft-reset is the process of resetting all the settings of the phone to the factory default! No applications are deleted.
Take backups of ur phone books,calender and others, then simply enter the code
*#7780#
It will ask for “Restore all phone settings-phone’ll restart….”
Then it asks for security code enter ur security code whose default value is 12345 then the phone is resetted after restart.The phone will be restored to the time when you purchased the phone.Default apps are not deleted.
2nd step :

Take backup of the contacts and other important data in MMC .
FLASHING
3rd step :
