Tips for a great answer:
This option restores the original operating system from the ROM.
Formats the C: partition and deletes all data including the memory
card. Key Code *#7370# (click this combination of keys on the keyboard in the mobile)
Important: To proceed to reset, the battery must be full and the
mobile device connected to the charger. If during the course of reset,
the mobile stop receiving electricity it can ruin the internal flash
memory of the mobile device and stop function.
Also know that is you have a series 40 device, this may not work in which case you have to reinstall the firmware which will restore to factory.
