Hello darrenianson and welcome to the BlackBerry® Support Community Forums.
Sorry to hear you are experiencing issues with your BlackBerry® Curve™ 8520 smartphone.
You will need to use the Force Detect method from KB10144 "How to force the detection of the BlackBerry smartphone using Application Loader" to reinstall your device software.
If you are unable to complete the software load as outlined above, then contact your point of sale to further investigate.
