Plug your phone into your PC and open BlackBerry Desktop Software. This article will help you reload your OS:

Re: 7.1 update corrupt

I've manged to get it working but on a downgrade, 7.0 not 7.1 if I update it, it will start flickering again and the screen will go blank. Do I just leave it and carry on??
