comment added 01-08-2010 by DJJB "I tried to install the mega pack as well through the Linksys Web Interface. Did the resets even the 30-30-30 way, but it bricked my router. The power LED flashes fast and the DMZ sometimes comes up for about 5 seconds. When pinging TTL = 100, but doesn't respond to the TFTP-tool anymore. If it's safer to install the mini version first, you might want to do that first to take less chances..."
