HI mate did you fix your issue ?hi I have a denon x2600h, I tried to restore the firmware but getting same issue 2a02 error. please help. how did u hook up to sound united ? and as u mentioned already the firmware site is no longer available. I don't want to pay that huge amount almost 50% of the avr.
by the way my issue is that no Sound. and I can't access the set up assistant menu. some how after filling around I could able to access the menu and hear Sound coming once to one of only connected speaker. I assume it's a software issue as well
Now I am in similar situation .. I emailed to [email protected] hopefully they will reply me soon.
