Denon S510 won't turn off. Screen just says "Update Fail". Unit unuseable.
Before I return this is there anything else I can try? Doing the factory reset does not work, unplugging for an hour and then turning back on displays same "Update Fail". Remote doesn't do anything, buttons on unit don't do anything. Factory reset won't work.
This started because I tried to do the firmware update. After it got down to 3 minutes the device powered off and then just got locked into this "Update Fail" mode. If I press the power button nothing happens. So weird. Brand new unit, out of the box for less than 10 minutes.
