I think I screwed my router

I have an R6400v2.  I was playing with firmware and I happened to flash v7000 kong firmware on it.  Now it identifies as a V7000, no 5GHz WiFi and WiFi barely works.  Is there any way to get back?!  Help please!

Hi, I had the same issue
Hi, I had the same issue (stuck with kong firmware on r6400v2) and I solved it flashing the Brainslayer build.
 
Check the following:
 
 
 
 
I used the netgear-r6400v2-webflash.bin file and it worked for me
 
cheers

The 6400v2 and the 7000 are

The 6400v2 and the 7000 are not identical. Even though they share some hardware it does not work that way... the chipsets are different. The fact that the 6400v2 identidies as a 7000 in DD WRT is more of an oversight than an actual "proof". I hope you are able to get it working... I installed the brainslayer build myself. At the time there is no dedicated Kong build for the v2 but I have read that he would make one if time permits... even though his 6400 build is meant for the v1 version it does work on the v2 somewhat. But I'd recommend the brainslayer build myself at this moment until other options arise.

I found a very annoying issue

I found a very annoying issue with the brainslayer build, I cannot loging into the 2.4Ghz interface, only the 5Ghz, I mean with WPA2 Personal and AES.

There are several users complaining of the same, while the issue remains the brainslayer is of no use to me, at least I could revert to the Netgear stock so this is where I am staying right now

The very issue is that DD-WRT

The very issue is that DD-WRT is detecting the R6400v2 and a 7000P. This is not just a cosmetic issue, it is a HUGE problem. For that very reason almost everything that is done to the router within DD-WRT can cause HW issues and/or loss of vital router information. Because DD-WRT thinks that it is operating on a 7000P it addresses the router as such, and that is the root of all evil. The 6400v2 and the 7000P have a different memory/chipset configuration so as soon as DD-WRT starts to write to the memory or operates the radio it can lead to problems. There is one exception: The first time you go from factory to DD-WRT the original settings are carried over and the build will operate normally. Going from DD-WRT to DD-WRT is however a risk and will most probably lead to a partially functioning router. I suspect that erasing NVRAM is dangerous for that very same reason.
