I really don't want to pay to park at Bright House again, and don't want a technician touching my setup.. (Working at Charter has tought me that most techs don't care and just want to get out of the house fast).
I had that same issue with an older MDN (non-C) box. (SA-8300HD) We were watching TV and all of a sudden the box went into a reboot mode, not a normal one, but the reboot with the countdown numbers when there is a software update. It never got past the last fill in square on the blue Mystro screen. Waited several hours, could get it to boot through the office over the phone.
They had to roll out a tech and replaced the box with an SA-8300 HDC. You got one shot in the dark left. Tonight, unplug the power cord from the cable box outlet and let it sit overnight unplugged. In the morning, plug it back in. If it gets past the Mystro screen and boots, you're OK. If not, unfortunately, you'll have to do a truck roll to swap it out, or take the box to a service center to swap it out.
