Prime Series Firmware v1.4.0 Now Available! I just downloaded the firmware update, as always opted for the USB firmware update… downloaded, unzip image file, copied to USB, when to update on my prime 4, it did recognize the update, click on update… and it did say that it will take a few minutes… then … It shut off…? 
It never came back on… so I press the power button… the Denon Prime 4 logo appears on the screen… the version 1.4.0 show’s on the bottom right corner… But . Nothing happens…? It doesn’t go pass this point…? 
VERY WORRIED!!! IT DOESN’T DO ANYTHING, OR GIVES ME ANY OPTION… I was on the 1.4 beta firmware before… any way to hard reset the prime 4 …? Or go back to previous firmware…? I try to conected to my laptop… nothing happens…
