One user reported problems updating to DDWRT, he reverted to stock, a few day later the router was dead.

He got another one which could be upgraded without a problem, so probably a hardware failure.

But first let me know what board_id this router has?

It is U12H332T20_NETGEAR

As I said this one was running Kong's build until it crashed on an upgrade. It has been on Kong's builds since the first builds came out and I have 11 other in family locations as well as three in my place (along with an r7800 and some Cisco NGFWs), so it is not a BoardID issue.

It has been up since I did the serial cable recovery on Netgears F/W with zero issues running a couple of stress tests on it.

My guess is a hardware failure, DDWRT uses other/more parts of the flash memory and if that is corrupt than you can not upgrade with DDWRT.

I just changed the Netgear f/w to a different version and working 100% which means the proability of the hardware failure in the flash is really tiny.
