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.
It not your fault.
As myersw pointed out, flashing via App, Genie, over wireless or automatically is risky at best and should always be avoided. Those of us who post here regularly can't keep up trying to get the word out. Recovery is typically possible, however. Usually timing, coupled with proper execution... and sometimes a little patience wins the day.
Given the unreliabiliy, I wish the option would be be removed as well.

There's some basic Mac shell navigation guidance here:

Plenty more on the Web.

With my weak psychic powers, I can't see what you're doing.

Ok. Copy+paste of your actual commands and results might help, too.
Before you run "tftp", do these:
pwd # Display your current directory.
ls -l # Show the files in your current directory.
ls -l *.chk # Show the ".chk" files in your current directory.
cd # Go to your HOME directory.
cd Desktop # Go to your Desktop subdirectory.
pwd # Display your current directory.
ls -l *.chk # Show the ".chk" files in your current directory. When you get to a directory where an "ls" command shows the firmware
image file, then the TFTP program should be able to find it, too.

I want to thank all for their help, support and advice. I was finally able to upload the new firmware. It was my fault that I had so much trouble doing so. Stupid rookie non tech savvy mistake. I copied the whole file to my desktop versus just the exe green file. Once I found the errors of my ways, the firmware loaded flawlessly and I'm up and running.
Again, thanks to all.
YAH! Glad you finally figured things out and are up and running. Be sure, if you have not already, to turn auto update off. Since your MAC connects to the router via Ethernet you can do manual updates of the firmware which is way safer.
Done & thanks again.
