this time its a little bit easier than v5 and v6 flashing


follow these steps

For v8, first flash vxworkskillerGv8-v3.bin from linksys webgui or debrick webinterface
(For gsv7 use vxworkskillerGSv7-v3.bin)

after the unit reboots, wait about 1 minute.
now plugoff the power cord and replug it in
now do the following
tftp -i 192.168.1.1 put dd-wrt.v24_micro_wrt54gv8.bin

and your unit will run dd-wrt after

please test this only if you're experienced with jtag since this has just been tested on one unit yet

and please provide any feedback on it

...or if you not familiar with tftp command, you can use Linksys's
Tftp utility
(leave password window empty)

Hello,
I am just writing to confirm that this method works; I had a little snafu using the tftp client from ubuntu, but the windows tftp worked fine from the command line. Thanks, you guys rock.

I don’t know if it matters but I had to push the reset button in the back after uploading the new firmware. Also if any n00b like me try this, it is useful to know that the user is root and the password is admin; had to do some digging for that.

Is there anything you would like me to report/test?

I followed these instructions but forgot about the waiting for about a minute after flashing vxworks. My router now has no access to the GUI and the wireless won't work at all. The DHCP server is enabled by default though and strangely that still comes through (which is useless for me though because my DHCP server is elsewhere on the network). I used the reset button on the back but now my router isn't even doing DHCP and still no GUI access.

Did I just "brick" my router?

if you didnt waited for a minutes you might brick it since the router is flashed with a new bootloader this time. so if you can't access your router at 192.168.1.1 by http after you pushed the reset button long while plugin the power cord
then its very likelly that its bricked. if it responds to ping on 192.168.1.1 its not bricked.

It responds to ping... I just can't seem to get into it via HTTP. And the wireless not working scares me because this is my only AP in the house which two computers rely on. :P

Should I try tftping the vxworks firmware (1st bin) again, this time waiting a bit to avoid issues, and then tftping DD-WRT onto it?

no. if it doesnt respond to http, it will respond to tftp so that means all went well.

so just do tftp -i 192.168.1.1 put dd-wrt.v24_micro_wrt54gv8.bin

into it. vxworks cannot be flashed with tftp
after tftp successfully transfered the binary, the router will be flashed which takes another 30 - 40 seconds. then dd-wrt will boot up and all is fine

I already did the DD-WRT onto it though...

Oh well I'll start again from that point like you suggest and let you know what happens. Thanks for the help here. Smile

This process ALSO works with the WRT54GSv7 with only a little HEX modification to the vxworkskillerv8!

*Of course, you'll have to reset the router to factory defaults before flashing*

Here's what I did:

1) Log into the WRT54GSv7.
2) Under the Administration tab, RESET TO FACTORY DEFAULTS.
3) Go back to the Administration tab [192.168.1.1].
4) Firmware Upgrade via the Linksys GUI vxworkskillerGSv7-v3.bin
5) Update will be successful.
6) Manually configure your Network Card to a manual IP something like 192.168.1.77, then Manually configure Gateway to 192.168.1.1, DNS to 192.168.1.1
7) Hold down the RESET button on router for 30 seconds.
8 ) Wait about 30 more seconds, then unplug router.

9) HOLD DOWN reset button, then plug-in router. Then release reset button after 5 seconds.
10) QUICKLY Open command prompt, and use TFTP command:
tftp -i 192.168.1.1 put dd-wrt.v24_micro_wrt54gv8.bin
11) You will see the activity light on your network indicator "go crazy".
[[If #11 doesn't happen AND you get TFTP TIMED OUT, I had to repeat step 9 then 10 to be quicker]]

12) Wait about 10 minutes, and the TFTP should acknowledge success.
13) Log into DD-WRT Router!!!!

Thank you BrainSlayer + Tornado!!! I just slightly modified your VXWORKS .bin to work this way, too!

GRRRREAT!

IT WORKS! Very Happy

Don't ask me why but tftping dd-wrt onto it again did the trick. Within a minute I was on the main screen. I don't quite understand why though because it's just repeating the step I already did again, but hey if it works I don't really care at the moment.

Thanks a ton for the dedication and hard work you provide for the community, Brainslayer! Coupled with the previous post, we can confidently say that the entire WRT54G series is covered as of today. I was considering buying another router to replace mine for DD-WRT functionality but now I can just use the one I have now. You can expect a donation to the DD-WRT project as soon as I turn age of majority and can (legally) use PayPal. :P

It should be worth noting though that there are still a few bugs present. My background colour on the main page is black and so I can't see the text unless I select it (control-a works easily) and reselect it each time the text refreshes. Also, there is a wireless client showing up on my list with a signal strength of 0. (and it really isn't there). So that's kind of strange. It's MAC address isn't that of my router either.

Just a quick note, I've had the WLAN go out for a few seconds, but after holding down reset button for 30 seconds, it came back up.

This could just be a bug to work out in these new WRT54GSv7's, but I just wanted to mention it.

Any suggestions?

*********edit*********
Thank you BrainSlayer -- I think I just changed too much stuff. Now, after re-doing settings, it still works WLAN 100%. I guess I was just having a temporary "hiccup".

I have some problems with my V8... Can someone help me?

I've been trying to install DD-WRT using a JTAG cable. First of all, I did a wholeflash and a CFE backup, just in case something happens. Then I started to flash a modified CFE so I could then flash DD-WRT, but something strange happens here: I can't flash a damn thing on it, not even my backuped CFE !!! Evil or Very Mad

I can perfectly read the flash and I verified my backups with a HEX editor... Everything is fine, except I can't write on flash. I even tried to modify HairyDairy's Debrick Utility so it could properly detect the BCM5354 CPU and the EON 29LV160AT chip, but it still doesn't work.

When I try to write on flash, the erase process is very long (but works) and then the flash process stucks at the first byte. Sometimes I can flash up to about 4% where it stucks again.

What's wrong with my router?
