How do i reset my Samsung SGH-J600 's password as i do not know what it is and it is not 0000 or 00000000?

This code when typed in on the normal dialling screen (when going to call someone) will reboot your Samsung J600, wiping it to it's factory default settings. All data, settings, passWords; anything on the internal memory, will be wiped. *2767*3855# Sorry if this isn't what you wanted. Enjoy world.
