I have tried *#7370# but it did not work?

Its obvious that the lock code is not correct,otherwise,the format would've worked.You can't format the phone without the lock code.

try 0000 .. or 1234 ... maybe just try rememberin anypassword u mite have changed. Last choice is to take it to nokia ..

Had you previously changed password for lock ?
If so, try to inser only the first 5 numbers...
I had some problems when i've inserted a lock code of 7 numbers (and confirmed those 7 numbers), but after locking i couldn't unlock with the 7 numbers i've defined... discovered after many attempts that only the 5 first are valid...
So if you defined the lock as "987654321" you should only insert "98765" to unlock

Hope this helps
