R7000
After uploading from DD-WRT: 04-01-2015-r26635 to the new firmware 04-09-2015-r26653 - I got a brick.
After switching - Power LED is blinking (white).
Web interface doesn't work (telnet too). I tried to reset button - but it doesn't work too...

I tried to flash it through TFPT2.
But after 80% loading - stops, error...
If I use firmware size 26Mb - upload is stoped on 60%, if firmware 18Mb (old from netgear) - upload is stoped on 80%.

Please, do you know - what I must do else?

Seems like 26653 is bricking all R7000 routers. Why is it still available and it hasn't been pulled?

Yes, I tried the steps from this link, but tftp2.exe doesn't work.
tftp2.exe upload firmware only 70%-80% - then stop.

I tried USB-TTL console, but I can't stop boot (ctrl-c doesn't work).
TFTP server is started automatically - and... Nothing work - can't upload, can't break, can't start...

I don't know what to do else...

Yes! SOLVED!
Maybe it will help someone Smile

My mistake is - I tried upload with TFTP2 util from netgear help ( http://kb.netgear.com/app/answers/detail/a_id/19841/~/reinstall-the-firmware-on-a-router-without-the-setup-cd-recovery-tool )

This util doesn't work with my brick (R7000).

I use USB-TTL for stop starting boot router, then type to console: tftpd
This command start TFTPD server.

Then I download simple - TFTP.EXE, and from command promt upload new firmware:
tftp -i 192.168.1.1 PUT firmware.chk

This simple client work fine!

I thought you said ctrl c didn't stop the bootloader.

Oh, yes. It is true with Putty - ctrl-c didn`t work.
But with old terminal client - work.

And, when I turn On router already connected to USB-TTL 3.3V - It didn`t start (freez led). I solved this - connect serial cable after turn On router.

Please, I need some help! Ctrl-c also does not work with my R7000. Which alternative did you use to do it?
