I don't have your phone. Have heard issues with some nokia phones. Personally, I have a Nokia phone and it died almost right on it's third year birthday with my cell company. I love the phone but it's got a bit gimpy.
As to your situation, I found this and whether or not it is helpful for you I take no responsibility.
