R9000 Firmware Flash Fails

I am trying to use TFTP to flash firmware to the device. 

https://www.netgear.com/support/product/R9000.aspx#download

 

However I am only able to get halfway when upgrading the flash and then progress stops and it says it can't reach the device. Does anyone have any suggestions?

   Why?  Why not use the usual update procedure?

   Define "halfway"?  What, exactly, did you do?  What, exactly,
happened when you did it?  As usual, showing actual actions (commands)
with their actual results (error messages, LED indicators, ...) can be
more helpful than vague descriptions or interpretations.

 

   Note that no third-party TFTP client program is needed for the TFTP
recovery scheme.  See, for example:

Re: R9000 Firmware Flash Fails

DD-WRT firmware is on the router. Trying to upload a image file via the web gui showed succesfull and then it just reboots back to the same DD-WRT web gui which shows it didn't re-flash. 

The picture I included was showing the tftp2.exe application which uploaded the firmware "halfway", you will have to click the link to view the picture.

I am going to try using the Windows TFTP Client command via Command Prompt going forward though.

   I did that, but it didn't tell me, for example, which file you were
trying to transmit, or to what, or how your computer's network interface
was configured, or much of anything, really.  (And is my memory failing,
or did you change the picture?)

   I know nothing, but I wouldn't bet that DD-WRT offers the same TFTP
recovery scheme as the usual Netgesr firmware.  I'd probably start by
consulting the DD-WRT documentation, with an eye toward how to restore
non-DD-WRT firmware.

Followed the below guide and used command prompt / Windows TFTP Client and got the firmware restored.
