Yes, I have a MR3020. I don't know the version off hand put will post in when I get home. I used the cord and Ethernet that came with the router and plugged both into my laptop. It booted up fine and allowed me to sign into the web interface. I downloaded the image linked to the instructions and after it was successfully installed, it prompted me to wait while it was rebooting. It never came out of the booting sequence and I was not longer able to log into the web interface. Telnet and ping doesn't work (will post script when I get home as well). Tried powering it down, as well as using the reset button with no luck. When I get home I'll try again with the power cord plugged into the wall adapter and see if anything changes.
