Just an update to the story...I spoke to Edward in support yesterday who suggested I go home, unplug the unit for a bit. He suggested I plug the unit back in, Master Power to ON, boot up the receiver, hook up the serial cable, and then hit the reset button in the back. He said this should cause the relay to "snap" off and then the firmware update should work.

I ran into a problem immediately. Since the failed firmware update, I had not tried to power on the unit completely. This was the first time. When I plugged the unit in, and hit the master switch on in the back, the amber light did come on. But when I hit the power button on the front, nothing really happened. The green light came on in the front, but nothing showed up on the blue display. I hit the power button (on the front again) and it the front light stayed green. It wouldn't power down to the amber light. I tried a couple more times. The unit appears dead right now. If I hit the reset button in the back, the light will go amber while it's depressed, but when I let go, it goes back to green on the front. No "snapping" occurs. I'm a little worried that the failed update hosed my receiver...I put another call into support and left a message for Edward. Hopefully we'll have some resolution soon.

Stay tuned!
