I still can't get my 3313CI to update. Keeps going into the loop of restart and retry. I can perform the network reset trick and the unit will work normally. But I cannot locate the firmware to do a flash by USB. I'm thinking this will be my last Denon product as I'm sick of stupid firmware updates that contribute nothing of meaning and only make life frustrating in their product usage. Integrate a wifi card into their own devices and a better processor. My TV, Xbox, playstation, apple tv, and every other device has this.
Going to call their worthless customer service in the morning. Sorry for the rant, but I'm tired of jacking with this after 2 hours. Technology in this day and age shouldn't perform like this is the first product to receive a software update.
