Open BlackBerry Desktop manager, remove the battery out of your phone plug it into the computer without the battery. Desktop manager will find a problem and it should ask if you want to update your OS, say yes, then once the process begins put your battery back in. The OS should re-install.
Man it's impossible to find anything on this site anymore, there was a Nuke how too with video, cant find it anymore.
try this link, its a bit more indepth step by step.
