I have a BB bold 9900 and I am getting the dreaded error 907 invalid COD if I want to update my BBWorld or Whats App. It starts downloading and then the error comes on. I tried the suggestions in this thread. I updated my OS and deleted apps. The problem does not resolve. Any help is much appreciated.
