It being a Broadcom based machine, look for "CFE Recovery" instead of TFTP. After booting with the reset button held down, the router would run a tiny web server with only one page to upload firmware. The web server would be at 192.168.1.1. but you had to static IP your PC because there is no DHCP server.

You might follow Netgear's guide on how to TFTP firmware, just to be sure...

That might be asking too much, since the linked articles in previous posts were STEP-BY-STEP, so, I'll help by posting the link, which is STEP-BY-STEP, but we'll see if more help is needed....
