I’m having problems with my Linksys EA6900 and I can’t solve it so I came here to ask for help.

I saw the threads on the forum, I saw the Wikia page but it was still a little confusing and I don’t know if I made a serious mistake.

My router is version 1.1, it had software 1.7 and I couldn’t downgrade, I tried via tftp and downgraded to the older version of the OEM firmware, after that I tried to upload the older DD-WRT which didn’t work. I tried again via TFTP and ended up confusing the versions and uploading the newer version, and therefore I was unable to rewrite the CFE (but I managed to backup the nvram and cfe as the text document explains).

To try to solve it, I tried again to flash the OEM firmware via tftp, I was successful, then I tried to flash the DD-WRT old version via tftp, I was also successful, in this version I flashed the XVortex CFE as indicated in the document and finally updated to the latest version of DD-WRT.

If possible I would like to upgrade to Xwrt, but it appears that it uses a different CFE with different mac assignment logic.

I tried flashing the new CFE through the newest DD-WRT that is installed but it doesn’t unlock, I tried flashing the newest version of Xwrt both through CFEWebserver and through DD-WRT’s WebUI and neither of them worked.

I’m not sure what to do, so is there a direct and safe way to migrate to Xwrt now? How?

How can I access the CFE recording again to migrate to the new Xvortex CFE? Do I have to downgrade to a previous version of DD-WRT before? If i have to, How? Which MAC configuration should i use? Is it possible to do this firmware recording process via DD-WRT WebUI or CFEWebserver?
