OK, joined the bandwagon. My R8500 bricked after updating from Kong's build: 30880M - 2016/11/14 to the latest 30910M - 2016/12/02.
The only firmware I could go back to is the netgear initial release(R8500-V1.0.0.28_1.0.15.chk).
All others builds, results in kernel panic while booting after successful firmware updates via CFE.

I am running into the same issue (although I am able to downgrade to at least one older version of the Netgear firmware without a problem.) I have tried the r8500 chk files going back several months and they all give the error. I also tried the ones on the myopenrouter.com site as well with the same results.
I wonder if we are dealing with a new revision to the model. I can't really find a number on mine that tells which revision it is unless it is this one on the sticker on the bottom under made in Vietnam:
272-12473-02
I am open to trying any suggestions anyone has.
Get a usb ttl adapter attach it and show me the output when flashing.
R = RX (Receive) Data
T = TX (Transmit) Data
G = Ground (0V)
V = VCC (Do not connect or you will release the magic smoke !!)
Levels are 3.3 volts, so you need an appropriate cable. The FTDI TTL-232-USB, RPI or something similar is what you need, you can get these from http://cpc.farnell.com for £13.50, stock code TTL-232R-RPI or SC12825
Connect the cable's TXD to the routers RXD and the cables RXD to the routers TXD. 0V / ground just goes straight through between the two.
You can capture the console startup text in most terminal programs. I use Putty (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html) Go into the Session, Logging options and set a filename.
The friend I was setting this up for didn't want to wait on me and opted to just use the netgear firmware so I no longer have this unit to run the tests and get the error messages. I notice on the www.myopenrouter.com forums others are having this problem, so I'll see if any of them can post the message to this board.
Whether I'm tech savvy enough to do this is debatable, but I'm willing to try. I'm currently a technology lawyer, but I was a full-time LAN engineer (on the software side) in the 80s and 90s. As such, if someone is willing to give me reasonably specific directions, I'm willing to give it a shot. I don't need a book, but links to the right directions or a reasonably specific list of "first do this according to the such-and-such wiki or page here", I can probably do this without screwing it up too badly. One thing in particular, as I would REALLY like to avoid frying my new router. The USB to TTL I purchased is this one (https://www.amazon.com/gp/product/B008AGDTA4/ref=oh_aui_detailpage_o09_s00?ie=UTF8&th=1). I did some online research, and it sounds like I'm supposed to connect three of the four leads, but if I connect the fourth, I'm likely to be smelling smoke fairly quickly. If someone can give me specific instructions for this one issue (e.g., connect the red wire to the R8500 pin labeled such and such) and which wire/pin I should not use at all, I would HUGELY appreciate it. Thanks!
Also, and this may seem stupid, so apologies, if someone can point me to directions regarding how to open up the R8500 so I can get to the pins, that would also be very much appreciated. Thanks!
I have the same Error Message, mine is the Vietnam version too, My model No. is R
8500-100PRS...
Error message when I flush Kong's firmware is : The firmware is not compatiable with your router. Error code -2.
I have two of the Vietnam manufactured R8500s that won't load firmware also.
Here are the results of trying to load the 1/18/2017 version out of the serial port:
# fileSize = 24006714
...............................................................................................................................................................................................................................................................................................................................................................................4366C0 HW only supported since V1.0.2.34_1.0.45

Could you please load Kong's test image below and provide us the console log from both routers?

It won't work, 4366C0 will also require some changes to the platform code side, as it bails out when probing the pcie bus and the radio driver is supposed to support the radio. Thus to fix this we need at least one router with the same radio as in the new R8500.
The error when flashing from webif is intentional until the build works we keep the signature of the build so no one breaks his unit. _________________ KONG PB's: http://www.desipro.de/ddwrt/

@Kong,
Only the new units like mine, was bailing out while probing PCIe bus.
However, Malachi's unit was able to successfully pass this phase and erroring during wl_module_init phase. So looks like his unit is older one.
Any idea why his unit also fails?
Thanks,
