Is there any way to reload the 921 operating system on a new or newly formatted hard drive? My 921 boots just to the Dish logo now. I was deleting some recordings when it locked up. I can make a successful image of the drive by attaching it to my PC and then booting the PC from a CD using Ghost. So I know the drive is physically OK. I think some pointers got messed up when I was doing the deleting. I own this 921, so I can’t get a replacement from Dish. What I really need is to get a fresh copy of the operating system, and then I can then download the latest rev from Dish. Any suggestions?
