Linksys WRT54GS-RM (CGNC) Same as Linksys WRT54GS v7.0
NOTE TO WINDOWS VISTA USERS: By default the TFTP Client is disabled and you SHALL NOT PROCEED UNLESS YOU HAVE ENABLED IT. To enable: click the Start orb and type the following into the Start Search field: "features" (Without the " " of course, but you have to tell some people). At the top of the Windows Start Bar, you will see "Programs and Features;" click on that. In the left pane of the new window, click Turn Windows Features on or off. Scroll down through the Windows Features until you see TFTP Client. Select the option box and press OK.
METHOD FOR EOC, INTEL, AND POSSIBLY OTHER FLASH CHIPS
(Note: My WRT54GS V7.0 didn't boot automatically, and simply power-cycling didn't bring it up. Resetting as described in steps 4-5, holding reset while plugging in the power cord, brought the router from "no lights, no web interface" to "functioning dd-wrt install.")
ALTERNATE METHOD TO FLASH DD-WRT ON A WRT54GS v7 WITH AN INTEL FLASH CHIP
I just loaded DD-WRT v24 RC7 on two of the WRT54GS v7 with an Intel flash chip. I used the latest vxworkskiller. Below are instructions. Intel chip says JS28F160, C3BD70, and A7397147. Router is dated December 2007. S/N starts with CGNC.
Another similar method to flash WRT54G v8 and WRT54GS v7.2 (possibly other 7.x)
I've been doing something slightly different on WRT54G v8 and this WRT54GS v7, it hasn't failed me yet, below are the instructions. I have done this on a countless number of WRT54G v8s and just did it on a WRT54GS v7 and it worked just the same. There is no resetting in the middle of this process, just do exactly what it says below, no more and no less. My WRT54GS v7 has a Broadcom BCM5354KFBG CPU and an EON EN29LB160AB-70TCP flash chip and 16MB of Samsung RAM. The FCC ID is Q87-WRT54GSV72 which maybe means it's a v7.2? Serial number starts with CGNE.
[Addition: tiger12506 adds that he has succesfully performed this on two WRT54GS v7.2 with CGNE serial numbers. He felt that it was impossible, that he had bricked one of the routers at first. Messing around with JTAG cables taught him some things, but... be sure(!) Be absolutely sure that you have tftp set to binary or octel. If you leave tftp in ascii it will appear to work but the flash won't take.]
Use the web interface to reset the router to factory defaults.
Manually configure network interface to 192.168.1.10. (Any address from 192.168.1.2 - 192.168.1.254 should work)
(In linux, this is sudo ifconfig eth0 192.168.1.10)
[For linux users: use tftp. You may have to sudo apt-get install tftp or your equivalent.
tftp> mode binary
tftp> put dd-wrt.v24_micro_generic.bin
As soon as that is finished do this: ping 192.168.1.1 /t (Windows only)
This will time out repeatedly and then the router will respond between two and six times.
The router will time out again a few times and then start responding to pings.
[At this point, tiger12506 had a little trouble, but after a long reset, and some short resets, more and more lights came on until finally the WLAN light came on and the router functioned normally running DD-WRT]
Set your computer to a static IP of 192.168.1.7. (or to whatever subnet the router is on) Disable all firewalls and security. Disable wireless on your computer and only have the router connected to the flashing computer by the ethernet cable between the two.
Hard reset or 30/30/30 (If the router supports it, if not, reset to defults in the GUI) prior to flashing. Wait. Check for password page on re-login and change password.
Flash firmware. You can use the webgui except if you have a belkin router. (For belkin use tftp.exe to flash)
Wait...at least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.
Do a power cycle of the router. (Unplug the cord, count to 30 and plug it back in.)
Wait for the lights to return to normal usually about 2 minutes.
Hard reset or 30/30/30 again (If the router supports it, if not, reset to defults in the GUI). Wait. Check for the password page and re-login to change the password. Then you can reconfigure your settings manually.
Once configured set your computer back to autoIP and autoDNS.
Important1: This Hard reset or 30/30/30 works fine for Asus router, but you do have to power cycle after the reset.
Important2: After you flash the firmware, and before you do the hard reset, the router will be building some nvram settings. YOU MUST WAIT FOR THIS TO FINISH PRIOR TO DOING ANYTHING WITH THE ROUTER INCLUDING A HARD RESET. Usually, you can tell when this process is completed by the WAN light coming on, but it does take several minutes. Go have a beer. There are starting to be more and more people who BRICK their routers by not waiting until the nvram is rebuilt, PRIOR to doing a hard reset. YOU NEED TO WAIT!
Reset to defaults
goto the Admin screen firmware upgrade, and browse to VxWorksRevert-GSv7-v3.bin, and click upgrade. During this time the Web browser may say upgrade succesfull and to reboot -----"Do NOT REBOOT"----- Wait for 2 min's and then reboot.
Goto http;//192.168.1.1 and you should see a mgmt mode screen, this is where you browse to the original Linksys Firmware, and and upgrade.
Wait for 1 min, even if it say's upgrade successful and to reboot, believe me, in my tests, it has not finished yet.

[DD-WRT v24 RC3] The WRT54GS v7.0 is now fully supported (if its not an intel chip - see important note below), but requires again a special flashing way, which is easier this time compared to the v5 and v6 vxworks killer.
All Chips are supported, just follow step by step procedure at:
WARNING: There are at least two types of flash chips that are used on the v7 router. Using this method with an INTEL-type flash chip will brick your router. There is not currently a solution for using vxworkskiller with the intel-chip v7 routers.
This procedure worked easy and great, the 1st bin file I installed with the admin. options in the Linksys control panel (the upload went about half way then tryed to reboot (then bricked my WRT54GS v7), following the procedure from the above mentioned site using this command "tftp -i 192.168.1.1 put dd-wrt.v24_micro_generic.bin" from the location of the bin file, worked fine had to HIT enter 2 times to excecute the command to install the 2nd bin file, now my WRT54GS v7 has so many features I need to find a good post for some tweak settings.
