Hi all,
I am trying to return to Netgear OEM firmware, but having a lot of trouble with this process.
Currently running Firmware: DD-WRT v3.0-r40559 (08/06/19).
Using the DD-WRT interface to upgrade to Netgear firmware only circles me right back to the front page DD-WRT interface after a few minutes
With 'reset to default settings', I get taken to the following page only to cycle back to DD-WRT firmware on reboot.
Using the tftp procedures on a Mac, I can ping TTL=64, but repeatedly end up with the error "Transfer timed out”.
Any help will be greatly appreciated. Please let me know if you need me to provide more detail.

Have a look a the the install guide and unbrick guide (in the second post ) for the R6400v2 in this thread: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=316399
Those routesr are more or less the same but you can not use the files from that thread, but the procedures are probably the same.
For the R6400v2 I made special Netgear stock files for returning to stock for an R6400v2, so not for your router though
I think that is also needed for the the R6400v1, I can do that but not at the moment.
What probably works is using nmrpflash that should push the stock file regardless of the header
Sometimes TFTP using the noheader option also works.

No probably to it. I am pretty sure nmrpflash is probably the only way it's going to TFTP because Netgears are special like that. Only other way is serial recovery with the other tftp software.
