Another problem!!!!

I had my box (the box super, starview3) working for a while, and it did its thing a few times updating itself and so on, and then it went to do it today and nothing happened, it would go up to about %150 percent and then go back to the channel with no result at all just a blank screen, then it would try to update again and do the same. i have hooked it back up to the pc with the null modem cable and and rs232 usb adaptor and flashed it with gtrom loader 8.00, only to go and plug it back up to the tv with the exact same results! no very happy at all! any ideas please?
