Well without knowing what rom or radio or anything your running it's kind of hard to help you, but I would say that by updating your radio/pri/nv and all that stuff you should be able to use ##3282#, Calkulin has a thread with the all-in-one file that will update them all at once, and he has the individual files if you prefer to flash them one at a time.
Ok just went and found the link to the thread where he has them:
