For DD-wrt 1/2:
[browserofchoice] 192.168.1.1 for linksyssmartwifi.com, check both boxes.
password=admin (if it never loads one of the screens unplug router, reboot computer, plug back in)
Troubleshooting tab, diagnostics tab, restore previous firmware button
If it asks for a file, give it linksys-ea6900-webflash.bin and skip to the next paragraph
If not, hold off on clicking yes. Open two cmd prompts. In one type Ping 192.168.1.1 -t
press enter on this one to let it ping, at the end it should say ttl=64
In the other just type tftp -i 192.168.1.1 put "C:\linksys-ea6900-webflash.bin"
(linksys-ea6900-webflash.bin being the file which is used for initial flashing, see below))
Back to the router webui click yes and the router will reboot.
Wait until the 4th or 5th line of ttl=100 in the ping cmd window to press enter on the tftp cmd window
If the tftp window says success after 45s or so continue to cfe
Otherwise if ttl=64 unplug the router and replug to try to tftp again when ttl=100 in the ping window
(up arrow in the cmd window to retry old commands)
Another possible solution is to downgrade linksys firmware as reported by @Bronzemaxell at page 7 of this thread: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=291230&postdays=0&postorder=asc&start=90
Timing is critical so you probably need a lot of retries but it is confirmed to work.
The linksys stock firmware for downgrading is attached to this post (FW_EA6900_1.1.42.161129_prod_DDWRT_upgrade.img). The procedure for downgrading is also covered in the attached DDWRT EA6900 Upgrade CFE instructions By Crashman and EGC.doc file
My EA6900 V1.1 is flashed with the DD-WRT r23158 using Linksys webGUI and I re-flashed DD-WRT r23158 again using DD-WRT webGUI.
My Linksys EA6900 now has the DD-WRT installed.
Can I now flash with the newer BrainSlayer DD-WRT firmware or I still have to install Xvortex CFE in order to upgrade the newer DD-WRT?
I intend to stay with DD-WRT and do not intend the router to become an Asus router.

Any help will be appreciate.
You can upgrade to a newer build, but you have to stay below 32K nvram usage, see the second post of this thread.
I have flashed the Router EA6900 with a newer DD-WRT r37882 firmware using CFE miniWeb server.
Do I still have to reset and clear the NVRAM after flashing to the newer DD-WRT firmware?

From 23158 to 37882? Normally a good idea to reset, but if you're not having any issues, don't worry about it. Is this setup as a primary gateway router? If so you should enable SFE on the Basic Setup page (unless maybe you're using QoS). Also, you should really be using at least build 41662 for the GTK rekey fix. Or just flash the latest build, for that matter, after reviewing the appropriate build thread. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#

Thank you jwh7 for your reply. I will flash with the newer firmware then. At the moment, I am just going to use it as an ethernet switch and wireless access point.

Hi guys,
I recently got a new EA6900 and as it turns out it was the newer EA69900 V2. Although I thought that it wouldn't be possible, I flashed to 1.1.42.16... without luck. Flashing process went well but the router didn't boot up, so I had to reset....
My question: is there a way to get dd-wrt on it or should I send it back?

Good catch!
Someone should update the wiki, anything more known about the "innards" of this router?
That's the only source of information I could find off the top of my head. That device has been asked about before in the forums, if memory serves. I just happened to remember to look it up on fccid.io _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"
