Hello
You could try doing a master reset but you will lose all data / contacts /pictures/ on your phone

*#7780# - restores user defined settings to factory default settings. programs, calendars, and contacts are unchanged. you will be ask to input your security or lock code to proceed with the restoration.

*#7370# - reprograms your phone memory to factory default. all files will be deleted. you will be ask to input your security or lock code to proceed with the phone memory format. backup your messages, contacts, and other important data before proceeding. NOTE: this is equivalent to hard format for Nokia Series 60 1st edition phones (N7650, N3650/60, N-Gage/QD). If you are using Nokia Series 60 2nd and 3rd edition phone (N6600 and above), this code will not fully format your phone memory, you need to do the hard format (3-keys combo code) instead.

turn ON your phone while holding together the green (call) button, *, 3 - reprograms your phone memory to factory default. all files will be deleted. you will be ask to input your security or lock code to proceed with the phone memory format. backup your messages, contacts, and other important data before proceeding. NOTE: applicable only to Nokia Series 60 2nd edition and above phones (N6600 and up).

SOURCE: i still could not reformat my phone because of the lock code

go for hard reset like this,if nothing works ,this is what I do
Hard Format :

Hard Format can be done if your phone is facing any of the problems mentioned below :

1. Blank screen. Phone unable to reboot.
2. Phone only able to boot-up to "Nokia" word screen.
3. Installed some program but not able to uninstall it after that.
4. Error messages such as "Child Installer" keeps popping-up.

Make sure cell battery is atleast 75% charged. If its not then you are putting your cell at risk. If its atleast 75% charged then do the following:

1. Switch off the phone.
2. Hold down the following three buttons: Green (call answer) button, * button, and '3' button.
3. While holding these buttons, press the power button and switch on the phone.
4. When the message 'Formatting' appears on the screen, release all of the buttons.

The procedure takes some minutes (approx. 3-4) so dont panic.

Note that you shouldn't switch the phone off or remove the battery when performing either of these operations.

Nokia phones can be reformatted with a special three-stroke keystroke sequence on power-up. When turning the phone on, press and hold all these three keys at the same time: "GREEN/TALK" ," 3" and " * " when powering up the phone. When formatting begins, release the keys.
Ensure the battery is fully charged.
