This has not been resolved as of today. I would like to suggest that Comcast look into their network on their boxes (internet). I have been these errors & have noticed that the port that my Comcast box is connecting to is not lit so there isn't a network connection to Comcast. Accrding to what is happening there needs to e a network connection to access the Guide, update software, & access Netflix ,Hulu, etc.
I checked my Comcast connections. I did the following:
Checked my network cable & it is functioning fine.
I plugged in another good network cable...no joy.
Plugged in the the cable directly from my Comcast riouter...still no joy...yes the cable is good.
All this with no help. My internet connection is great...working fine. So that couldn't be the problem. It's the connection between the box & Comcast servers.
I was thinking that the update isn't taken because the network isn't working between Comcast & the TV boxes. So software does get updated in the boxes.
I know you guys are "experts" but you need to check out any suggestion from anyone!

The link that was posted goes to some "500 Internal Server Error". so that isn't the answer. Maybe Comcast is doesn't want us to find the error or the support staff is smart enough to find the answer. They just give you the standard answer for any problem, get you off the phone & on to the next call.
