Router Backdoor for When Your Upgrade Goes Awry

Hopefully this helps someone else, but it’s mostly for my own edification for if when this issues happens again. This pertains to the Netgear Nighthawk X6 | Tri-Band WiFi Router | AC3200 (R8000) but I’m sure it apply to other (similar) routers. If you’ve ever used a Netgear router, you might not have been a big fan of it’s management UI. I wanted more control over my router so I opted to go for FreshTomato. After a few months, I decided to go through the upgrade process.
