I'm running the 4/6 firmware on my Netgear R6700-V1.

I was trying to disable all the annoying bright LEDs on the front, and ran this script I found for the R7000 in my Startup script.

Code:
for i in 2 3 8 9 12 13 17 18 ; do gpio enable $i ; done
for i in 14 15 ; do gpio disable $i ; done


On reboot, most of the LEDs turned off, but the LAN lights were still flickering, so I SSH-ed in and tried to enable/disable a couple other gpios not listed in the script (stupid, I know, and I now know these last lines of code at https://forum.dd-wrt.com/phpBB2/viewtopic.php?p=1061297&sid=88eaf54625244acc3e28a2dac32e31b6 might be the fix for the LAN LEDs). When I entered

Code:
gpio disable 7


The power LED came on and turned orange, I lost my connection, and the router rebooted itself. But then I couldn't connect anymore wired or wirelessly. I tried opening up my subnet and pinging the default IPs and the old IP, 192.168.0.1, 192.168.1.1, and 192.168.48.1, but nothing came back.

So right away, I tried to factory reset by pushing a paper clip in the hole for 7 seconds, then tried again holding it for 30 seconds. Now I see a dd-wrt protected SSID being broadcast and the LEDs are back to normal, so looks like it factory reset itself. However,

    When I'm hardwired in set to DHCP/automatic for everything, I get an IP address of 192.168.0.126 but no gateway (and it says No Network Access in Windows)
    I can't ping 192.168.0.1 or 192.168.1.1, even when I set everything manually
    arp -a doesn't give me any real physical MAC addresses, so it looks like the router doesn't have an IP address
    running a layer 2 LLDP scan, I see no devices
    running a Wireshark scan while plugged into the router, I see nothing to/from the router


Is there anything I can do besides throwing my router in the trash?

You should be getting a 192.168.1.x IP. You should only have to push the reset button for ~10 seconds when powered up. Not sure if you enabled some magic voodoo recovery mode, but it would be using the 192.168.1.1 address if so. Try resetting with the button again.

Fixed! I was able to get into the dd-wrt SSID by using the password listed under the router, and from there I could use my restore using a router IP of 192.168.1.1. Whew. No idea why hardwiring wasn't working.

Could've been something to do with holding reset too long, no telling. Marked as solved, glad you got it sorted.
