Yes, completely powered down, disconnected, reconnected the HDMI back to the Hopper. Everything is working again now after so many reboots. It all started when I tried to update the software. I've been getting the software update messages every day, but it never goes to the newest release. When I tried to go into the menu today to upgrade, it started the process of dozens of consecutive reboots. It would land on the starting channel, go a few seconds, freeze, and then reboot again. Now I have no idea which device is failing, or is this just some sort of update failure and both devices are fine
