I just did the latest firmware update for my Denon 4311CI receiver. It said it would take 6 minutes but when it gets to 5 minutes it shuts off and then comes back on and goes back to starting the firmware update. It constantly goes through this cycle. I tried turning it off after it kicked back and before it started the cycle but that did not work. I even tried unplugging it but that did not either. I also went back in to the menu and told it not to do the update but to no avail. Any help would be greatly appreciated.
