Seems to confirm the problems that some are having with flashing dd-wrt on the newer 3200acm. Only models with the serial # starting with 198106 can be flashed.

Thanks for the link to a very nice writeup about the wrt3200 and not being able to flash.

Yea that issue has been confirmed for more then a week at least here on these forums.
They seem a little slow on the uptake there.

This is the response I got from Linksys when I asked why I have two with idential version but one is supported and the other not.

"The WRT supports currently available 3rd party firmware if the serial number starts with 19810 since it has the original flash memory. If the serial number of your WRT starts with 19811, it has a newer flash memory which is why currently available 3rd party firmware does not work.

The OpenSource community is responsible for providing firmware fix for the 19811 SN flash memory. The community usually takes a bit of time to produce new firmware that will work when changes like this occur. We recommend reaching out to the OpenSource community for updates. "

The latest build, r35034, should contain a fix for not being able to install DD-WRT on newer WRT3200's. According to svn change r35033 contains a patch to fix the nand install issue.

That's good to hear... I'll probably have some time to attempt this tomorrow

I find it hard to believe all those folks who were stuck aren't trying this, WTF???

[myersw]

Agree. Lots of folks not able to install and now that there is build with a fix everyone is very quiet. Wonder what would happen if I started a thread about this build.

Maybe they all took my Asus or Netgear suggestion.

UPDATE
Created thread.
