Re: How to unbrick the Nighthawk R7000 using OS X and TFTP

HI,

thanks youve saved me a lot of headache, after my router suddenly appeared with an unportected LEDE wifi, and was unreachable on all regular addresses. Dont asl, I dont know how this happened.... must have been an interuption of the cable modem setup in the dorm...

 

all in all I used your guide succesfully to return to the original firmware. 

 

1 addition to be made though: I needed to powerdown the router, and hold the pin, pressing the restore factory settings during powerup, all the way to the green power led blinking.

 

After that, I uploaded the firmware in 2 seconds !

Might want to add that for reference for other users.

 

Thanks again1

Re: How to unbrick the Nighthawk R7000 using OS X and TFTP

Thanks for the info. 

Glad things are good again. It is a pain to have to do a tftp. 

Make sure of two things. 

1. Make sure the auto update is turned OFF. 

2. Only update the firmware via a PC/MAC Ethernet connected to router and do a manual update.

Re: How to unbrick the Nighthawk R7000 using OS X and TFTP

Thank you! This got my bricked RBS40 Orbi Satellite running!

 

I bought it off ebay and it came this way. So glad it's not in the trash--thanks to you.

 

For those searching the web for a similar woe:

Symptoms: ring was blinking white for about 30 seconds, then suddenly amber, milliseconds, green, black; repeat.

 

This article combined with the following is what I relied on: https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP

Re: How to unbrick the Nighthawk R7000 using OS X and TFTP

Forgot to add to my reply yesterday, 2019-11-03 05:50 PM, the key that helped me:

 

pinging the ip address (step 3 of kryptonix's original post). Leaving the ping running, I learned there was a pattern of connectivity and that eventually the connection stabalized. Once stabalized--like 10 minutes after the hold-reset-button-down-while-powering-on step (steps 7 through 9 in kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP )--I was able to do the TFTP transfer.

   Presumably, there was a "put" command in there?

 

> [...] after a while it replied Request timed out.

 

   With my weak psychic powers, I can't see what else you did, but
"Request timed out" suggests that no one is listening at the (invisible)
IP address which you gave to the TFTP client program.

 

   The TFTP recovery scheme is a multi-step procedure which offers
multiple opportunities for user input, hence user error.  By itself,
saying that you tried it doesn't say much.  Especially when
using a command-line program, copy+paste is your friend.

 

> [...] i can connect the router [...]

 

> Model: EX6120|AC1200 Dual Band WiFi Range Extender

 

   That's your target/failing device?  That's not a router.

 

   I don't know that TFTP is supposed to work with an extender, or, if
it did, what the extender's default IP address would be.  And you're
connected to it how?

 

> [...] what elase can i do?

 

   Start your own thread for your own problem in some more appropriate
forum?

   Not very well.

 

> tftp> connect 192.168.1.10

 

   "192.168.1.10" is (or should be) the address of your computer.  Your
computer is not running a TFTP server, so you get a time-out when you
try to talk to it that way.

 

   You want to connect to the router/other-device at _its_ default IP
address (which, I gather, is that same as for a router: "192.168.1.1").
For example (without the wasted time/steps):

 

      $ tftp 192.168.1.1
      tftp> binary
      tftp> put <your_file_name_here>

   Not a useful description of what you did.  _Which_ "the process",
exactly?

 

> [...] (see attached image)

 

   Copy+paste of the plain text would be more helpful than a picture of
the plain text, and your picture does not show the initial commands.
However:

 

      Connected to 192.168.1.10

 

suggests that you didn't read the previous post:

Re: How to unbrick the Nighthawk R7000 using OS X and TFTP

Thanks for the quick reply.

 

A little bit of backgroud with my problem.. I updated firware to ExpressVPN and after that event I am not able to access the router admin settings. Neither Netgear nor ExpressVPN. As a result, I want to delete the new ExpressVPN firmware and replace with Netgear.

 

I know expressVPN is 3rd party and Netgear cannot provide support. But I've learned my lesson and what I want is to return to original settings.

 

Regarding your instructions, new IP address of the router is 192.168.132.140, which I used for the transfer firmware commmand and did not work

   That would have justified starting a new thread for your different
problem, rather than joining this old, largely unrelated one.

 

> [...] I updated firware to ExpressVPN [...]

 

   You might have tried.  It might have worked.  What are the LEDs on
the thing doing now?

 

> [...] new IP address of the router is 192.168.132.140, [...]

 

   Says who?  I know nothing, but, as I read the instructions,
installing ExpressVPN on an R7000 should leave it listening at
"192.168.0.1" (which, note, is not what the default would be with
Netgear firmware on an R7000):

 

      https://www.expressvpn.com/support/vpn-setup/app-for-routers-netgear/


   If the router firmware really is scrambled, and it's scrambled
Netgear firmware, then I'd look for it at "192.168.1.1".  If it's
scrambled ExpressVPN firmware, then I'd look for it at "192.168.0.1".
Anything like "192.168.132.140" _might_ make some sense if the
ExpressVPN firmware is _not_ scrambled, but what do I know?

 

> [...] which I used for the transfer firmware commmand and did not work

 

   Regarding "did not work", look (way back) in this thread for "Not a
useful problem description [...]".

 

   VPNs (about which I know approximately nothing) tend to involve new
(virtual) networks, which may involve different, unexpected
addresses/subnets.  Some confusion may be inevitable.

   Instead of posting a terse/useless problem description in multiple
years-old threads, you might get better results if you started your own
thread for your own problem, and included a few details, such as what
your router does, what you did, and what happened when you did it.
