I got it... I had to open it up and short pins 8-9, then it would take a full file transfer via TFTP. Works like a champ now. FYI for others, it's not hard to short the pins, but it requres a magnifying glass and a needle or something with a small enough tip to short the pins together.
The 30/30/30 reset did nothing for me.
The info in this link helped, also:

By the way, it still wasn't as easy as 1-2-3 after shorting the pins. I had to attempt the file transfer about 3 times before it took it. You'll know when it takes because the router will reboot almost instantly.
