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.
Apologies for the multiple messages, diregard the previous one.
Some context first:
I have a r8000 which i understand is very similar to r8000 in terms of troubleshooting. I was trying to flash the router with Advance tomato. The firmware seemed to be correctly installed but clearly this was not the case as after the installation was completed the router got stuck in what i believe is a reboot loop. after spending pratically all night trying to resolve it I came across this post. I followed all the steps mentioned and i got until the last one where after i send the command to install the latest version of original netgear firmware i receive the message, like many others above, "request timed out".
I diligently read the advise that antinode gave to previous users and therefore see below the copy and paste from the two shells i have used to type the commands.

it seems to me that there is no enough time to install the firmare as the router keeps re-booting?
techtherapy kryptonix antinode any guidance much appreciated -
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:

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.
