Mini in Boot Loop?!? Recommendations

I've got a couple of V2 Mini's and have never had a problem with them but now one of them is in a boot loop. It never gets past the initial TiVo logo. I didn't even know they could get in a boot loop. They both on MoCA and were working right up until the software upgrade the other day.


I've unplugged the power for several hours, and unplugged and replugged the HDMI and coax but nothing help.


Suggestions?


Thanks.
