Mine apparently was in the middle of being updated and I didn’t realize it. It was not coming on so I immediately power cycled the DVR.  I'm guessing now not a smart move as I saw one gear, then two, the red X with two dots.  I did the ATT chat thing and they had me power cycle again.  That time it did come back up, but all my recordings were gone (big bummer).  That lasted about an hour then the screen froze then went to the three circles (I think), I power cycled again and after it went through the gear stuff again it's hung at the red x and two dots.  Any ideas or suggestions would be most appreciated!
