Maybe try relocking and trying to restore the closest u can to the stock version of your phone.
Another option would be updating your entire phone to the newest bell rom (with the newest radio) and then NOT letting customizations run. That might also work, although trial and error is essentially what I would be doing right now =p
heres a link to the bell rom: (bottom of page)
