Nighthawk R7800 looks to be bricked. At my wits end.
I've been trying all morning and afternoon to get my Nighthawk router back online after a bricked firmware update. I have a white light on the power led and it flashes. I'm trying to use TFTP2 with a...

I have TFTP'd an R7800, albeit not one with broken firmware. (It was some magical intervention during a beta test.) But I do know that TFTP can be a tricky operation that can take several attempts.
Apart from the timing, a particular issue can be the location of the firmware and the place where you start the TFTP session. Ideally, they should be the same place. You don't want to be faffing around with "directory" (path) instructions in the TFTP commands you issue. Start the process from the directory where the firmware sits.
I'm trying to use TFTP2 with a lower firmware to try and reflash it.
Why TFTP2? You would be better off using the native TFTP in whatever (unknown) operating system you are using.
Netgear's TFTP guidance tells you how to set it up in Windows with a pointer to Macs.

By the way, you may be able to prod the router into "recovery mode".
- Press reset for 30 seconds
- Keep pressing reset while removing power
- Keep pressing reset for another 30 seconds while apply power
If that works the standard firmware flash may work.

I tried TFTP orignally and wasnt able to get it to work. I got the same error message as before. No responses from servers I beleive was the message. Like I said in my first post I've been trying everything to try and get this back online. I've put the router into "recovery mode" or at least did those steps. I've gotten a solid orange power led and the standard flashing white led.
Did you run the command prompt as an administrator? Right click on it and "run as administrator"
when tftp had issues, what error were you getting? details are key with helping on these

Which is it?
Blinking amber is corrupt firmware.
A flashing white led get you into TFTP recovery mode.
That's where you want to be.
currently just the flashing white led. Same issues as above trying to load the firmware
