I am getting the same exact error that the original poster did trying to go from .795 to .806 Shows the update and when I press the update button a grey box appears for a second then disappears. After that it will show I have an update available but will not let me press the button to update as it is greyed out. Have to reboot by cutting power then it happens again. How can I get it to update or what can I do to fix?
