Has anyone done the firmware update (for additional decode options and faster auto-detecdt) on an HK 630 themselves ? I dug out a couple of old PCs recently that had actual serial ports so seems like something I should try over the weekend... but on the other hand the receiver is now old enough that if I do screw something up it might be hard to get a replacement processor (ie one with non-screwed-up flash). Thoughts ?
I loved my HK-630, but lack of hdmi forced me to upgrade years ago. It's still sitting on the floor of a closet. I did do a firmware upgrade on it myself long time ago. From what I remember, I didn't have the correct cord to hook up to the serial connection. Once I had the cord, the upgrade went fine. It definitely isn't the easiest thing to do.
