Netgear 6700v3 bricked, tftp doesn't work, no ping to the router
Hi there, I tried upgrading my firmware (over wifi, I had no idea I wasn't supposed to). Anyways, it's now pooped and flashing orange. I've gone through most of the existing posts in this community,...

I downloaded nmprflash, and it worked first try!

Thanks for the quick response! It ended up being a newbie error, I had the ethernet cable plugged into the yellow WLAN port, instead of one of the 4 other ones. I can ping the router now, so i'm a step closer, but still no dice.
I'm currently trying the command line TFTP recovery scheme:
Static ip set to 192.168.1.10. Subnet mask 255.255.255.0, default gateway 192.168.1.1
tftp -i 192.168.1.1 put R6700v3-V1.0.4.84_10.0.58.chk
Transfer successful: 48283706 bytes in 35 second(s), 1379534 bytes/s
It says successful, but the power led is still blinking orange, never turns solid.
I'm having trouble with:
"Count at least 10 flashing power LED and release the reset button."
When I turn on the router while holding down the reset button, the power led flashes, along with all the other leds, pretty sporadically. I ended up holding it down for probably a minute.
When I restart, my pings look like:
Reply from 192.168.1.10: Destination host unreachable.
Request timed out.

Request timed out.
I execute the tftp command right when it hits the first TTL=100 reply.
I have also tried the tftp2 GUI client, which seems to Upgrade, but fails halfway through and never successfully completes.

Update: after some googling, it’s the exact same issue as https://community.netgear.com/t5/Nighthawk-WiFi-Routers/R6700v3-bricked-after-firmware-update-failed-not-fixable-using/td-p/1840178
There isn’t really a clear solution, other than “wait for the first ping response, and then run the tftp command”. I’ve been trying this for the past hour with no luck. I’m also unable to get my router into the mode where the power led flashes white, it’s just constantly amber, or all the leds flash like christmas lights (right after startup)
