Firmware error when upgrading

I just received a new Nighthawk x8 R8500 router. I successfully updated teh stock netgear firmware to the newest netgear firmware, but I am having difficulty upgrading it to ddwrt. I have tried the Kong R8500 chk download file from this site and the R8500 ones from ftp://ftp.dd-wrt.com/betas/2016/11-14-2016-r30880/ but I get the following error no matter which R8500 chk file I try.  I have even done the 30/30/30 before trying the update, but I still get this error.

The firmware is not compatiable with your router. Error code -2. 

Any thoughts on what I should try next?

Have done resets from the Netgear interface and tried 30/30/30 reset as well.

Seems there is a new revision

Seems there is a new revision/signature.  From the looks of it, it is the Made in Vietnam models that cannot be flashed but the Made in China models can.  Unfortunately my amazon unit picked up 2 weeks ago is a Vietnam model and I get the same -2 error trying to flash.

I had posted this issue to

I had posted this issue to the dd-wrt forum.  They sugested using a usb ttl adapter and posting the output when flashing to the forum so they could assist fufrther.  Unfortunately the person I was setting this up for didn't want to wait so I no longer have the unit to try and flash and give them the output.  Here is the thread if anyone else having issues wants to get their help roubleshooting.

Hmm... It seems that Netgear

Hmm... It seems that Netgear UPGRADE the hardware of R8500 to solve the problem of BOOT LOOP...

I got the 3rd R8500... I hope this one can live for a longger time... The BOOT LOOP of R8500 was take me to the hell since I got it first time...

I was already updated it to V1.0.2.86_1.0.75 of the official firmware. Watting for the update of KONG version now.

Could it be they are two

Could it be they are two diffrent routers? one is an R8500, and the other is R8500 Nighthawk X8, just a question.

I successfully updated

I successfully updated Vietnam model firmware  to DDWRT using firmware found here:

https://www.myopenrouter.com/download/dd-wrt-kong-mod-netgear-r8500-2017...

This is the first firmware to not get the error code -2 message.

The firmware error you are

The firmware error you are facing while upgrading is really so bad thing. I want to suggest to do the router's software update first. After that I believe the problem will be solved. If not solve then you have to learn how to Fix Wii Error Code 51330 because this is error code is similar to firmware updating problem.
