R6400 FW upgrade won't work-wrong FW message

I tried upgrading my brand new netgear R6400 with the DD-WRT FW from Kong. It goes through the message that I will loose connectivity. There's a quick update bar and then teh ewrror message comes back and says I have the wrong FW. I have tried different versions including the latest dd-wrt.K3_R6400_0.chk.


Tried different browser

Tried different versions

Updated to the latest Netgear FW

Reset to factory defaults

Trying to upfate using the Netgear FW update located in the advance section under administration.

Hi tbirdman...my immediate

Hi tbirdman...Just joined this forum, and your post was, frankly, a bit disheartening, given my reading about the FCC recently.

My immediate thought, even though I have never even used a router before, was that allowing the "Latest Update of Netgear FW" would push us into the new world of no-flashing-open-source-FW.

Yeah, bummer post, right out of the gate. Could this be the problem, given the type of error message???

So I was careful not to update my brand-new Netgear R6400 AC1750 when I set it up. I made sure it was made before June 2 ,2016.

These links require a close reading...

From here--       https://www.wired.com/2016/03/way-go-fcc-now-manufacturers-locking-routers/

"Hey, remember when the FCC reassured us last year that it wasn’t going to lock down Wi-Fi routers? And everyone breathed a sigh of relief, because custom router firmware is actually a really good thing? Sure, it’s fun to improve your router by extending the range or making your network friendlier for guests. But open firmware is important for other reasons: it enables critical infrastructure, from emergency communications for disaster relief and building free community access points to beefing up personal security.
Well, there goes that. Because even though the FCC said its new requirements were not intended to lock down router software or block the installation of open source firmware, at least one large manufacturer has reacted by doing just that. And more could follow.  ..."       I removed the links, which have much info.

and this article--       


Also, maybe try out a lean Tomato version?

NETGEAR has publicly said that they won't block open source firmware. Also none of their latest stock firmware releases talk about some kind of blocking or prevention of loading open source firmware


Also, the FCC recently even forced TP-Link to allow open source firmware so it seems not so bad after all

Here's more; gosh, it gets so contentious. The news moves quickly (all I did was step out ot help build a fence, and missed out)     Knitter

Flashing DD-WRT from the

Flashing DD-WRT from the factory firmware is a two-stage process.  First you must flash Kong's dd-wrt.K3_R6400.chk image, and then once that is running, use it to flash the full image dd-wrt.v24-K3_AC_ARM_STD_128K.bin
