can someone help? I have a Denon 2910 and decided to do a firmware update - I downloaded from web site denon2910.freehomepage onto a CD firmware update ESS 6720-8 and followed the instructions detailed on the site - after the Cd was loaded "writing" came up the front panel, I then switched off and then back on again and then pressed play, forward skip and open/close at the same time for 3 seconds, the instructions says that "initialized" should appear! but in my case nothing and when I now switch on no functions operate on the DVD player or remote, the front panel constantly says "loading" - can anyone assist?
