Remember, do not let go the 3 press and hold keys until you see a formatting word screen show! 2.

When you format your phone, all data saved therein will be erased. Copy your contacts to your SIM and save your files on your memory card. To just reset the phone to its original settings, dial *#7780#, press YES then key in your lock code.The phone then restarts. Default lock code is 12345. This will not erase files and contacts on your phone. To format the phone, dial *#7730#, press YES then key in your lock code.
If you do not know the lock code, turn off the phone. Press and hold GREEN, * and 3 buttons while turning on the phone. Press and hold until hands appear on the screen.

12345 s the default security code for nokia....if u forget the code then do one thing..better re install the firmware....all ur settings ll come to the factory setting position...but make sure u have all the contacts as it ll get erased during the process.......

motorola passcode is 123456
nokia 0000 or 12345.

TRY THIS
TOOLS>SETTINGS>PHONE>GENERAL>ORIG.PHONE SETTINGS>THEN UR CODE { IST TRY 12345 }

just remove your MMC n just type *#7370# n will ask u the security code.type it out (default code is 12345 )
NOTE: battery must b full, else if format is disrupted by low batt, consequences will b disastrous
I heard the code *#7780# works too, pretty much the same i think.
