How to unbrick the Nighthawk R7000 using OS X and TFTP
Hi,
After spending a night on unbricking my R7000 and how I struggled to work with all the manuals out there but none of them actually worked. I thought I should share what actually worked for ...
HOLY COW IT WORKED!!!
nmrpflash worked!!! Switching to a Static IP address and turning my Wifi off did the trick!!
Also, recommend using -vvv to double check when it works. Took me two tries to nail the timing because the router has to finish restarting for the packet transfer to begin before the command times out.
I have an R6700 and this is the closest thread I've found to mirror my issue. After getting to the last page, I notice I'm having the same exact problem as seethelight . My router keeps rebooting constantly and, via the ping command, I notice that it's only on for 4 seconds, and then restarts again, running through the restart loop for 93 seconds, at which point it's connected again for 4 seconds and back to restart.
Seems like this is not enough time to execute the TFTP command.. Wondering if anyone found a solution to this? I tried using a different power adapter and problem persists, so the power source is not the issue. Tried hard resets but also doesn't help.
PS: this happened after I set the router to repeater mode.
PS2: not sure if I should open a new thread?
Here's the file in my desktop, using an old one because it was the one that ran more stable before this mess:

Brunos-MacBook-Air-2:desktop bruno$
Here is the reboot pattern. I leave the router on and it does this forever:

And here is the TFTP command I'm running. I'm doing the put exactly when I get the first ttl=100 response from the separate terminal window where I'm pinging the router:

unfortunately i wasnt able to resolve it. Still hoping that someone pops up here with a solution. I also tried with the 4 pins cable but to no avail. If someone could post here all the steps to follow with the 4 pins and mac would be great but to date i have no solution to offer.
