So mine just started doing this on Friday but I'm not sure it's exactly the same situation. I have a reboot loop but only get as far as the "Starting Up" screen then I get a message that it's going to take 3 hours to fix, then a reboot, then rinse and repeat. Did that all weekend, called them this morning when they opened and got "it's a know issue, no ETA, but we'll let you know". Unfortunately I'm 2 months out of warranty with this box but I'm going to give then a day or two, then call them back and see if I can get a new out out of them. If not I'll threaten to cancel all 4 of my boxes and see where that gets me.
