I've tried the 30-30-30 technique on my DIR-825 and never get the amber light or firmware update web page. I've tried holding in the reset for many minutes before, during, and after powering off/on. It appears to be running the reset over and over again and never going to emergency setup. In fact, the amber light never goes on, even when powering up normally. I only see blue lights.
I just updated to the latest firmware through the Tools>Firmware page; the unit seems to be functioning normally. Any ideas on why I can't get into emergency mode?
