Rx-v673 firmware update issue!
Hi I'm new to the forum and would love some advice.
I have just installed an rx-v673 and it works great fantastic in fact but I connected it to the net (hard wire for speed) and it started to download the new firm ware. Part way through it displayed "Error! 2000" so I called a yamaha dealer. " oh yes sir, happens all the time the Internet has been interrupted, simply unplug leave for a while plug back in etc...) so I did. But when I turned it on it displayed ROM issue ( or something similar). So I then read on a forum to download the data on to a USB and update via front panel. So I did but now it starts by saying verifying but then informs me of "device error" or something any advice to get the best amp I have had back to working status
