My R7000 never booted back up after the 1.0.7.6 firmware update that I initiated trough the router web portal yesterday. I thought it was still updating when I didn't get a response after 30 or so mi...

Hello Max_F,

 

Do you mean you bricked the router after an online upgrade?

I upgraded offline, I mean from a firmware file stored on my disk.

 

May be there is a risk in your case, but I don't know the reasons (bad temp file or other).

I think it is interesting to discuss this point with other users and/or Netgear support...

Max_F If you can still ping the router, I suggest that you try to follow the steps from this link or try another TFTP client. 

However, if you cannot ping the router anymore I suggest that you contact support to get an RMA.

    Thank you for the suggestion Elaine! Yes, I'd tried with multiple. Unfortunately neither tftp, tftp2 nor tftpd64/32 made any difference. Strangest thing is that the router is still pingable and gives a perpetual TTL=100 response so I'm assuming I would need to break the loop with a jtag-cable if I've read the "unbrick your r7000" posts correctly. As I've said before the fix seems easy enough but would void my warranty. I'm waiting for a replacement unit right now but still have the old one sitting ready to be shipped if anyone has any commands they would like me to pass to it in hopes of reviving it.

      vxd79 You're pinging the router, right? If you have tried the suggested steps and won't work then contact support for RMA.
