WRT54G V2 Bricked?

    My very old WRT54GV2 router had 1.28 Tomato firmware on it, but in anticipation of DSL being installed tomorrow, I wanted to install DD-WRT so I could partition into 2 VLANs. The first step was to flash with the latest Linksys firmware, FW_WRT54G_4.21.4.000_20110712.bin, downloaded from the Linksys web site. The Tomato FAQ said nothing special was required, to just go to
    Administration/Upgrade, select the file and click the Upgrade button. This I did. When the router rebooted, the Power LED flashes rapidly, after a few seconds the WLAN and LAN
    s light, then go out, then the WLAN
    light comes back on. The Power LED continues to flash rapidly. If I connect a computer to a LAN port, the
    for the port lights, but the router does not respond to pings, they time out. I've tried the 30/30/30 hard reset, several time, with no change. Is this box truly bricked or is there some other procedure, other than pin shorting, that might restore it?

    Same thing. I have also tried the pin shorting and I can get the device to ping again but no admin web page comes up and when i upload the new firmware again using tftp, it stops pinging and the update process fails. I think the new firmware is no good. Anyone have an older firmware file for the wrt54g v2?

    I have a WRT54G_v4.21.1_fw.zip file from 11/2006.

    nreiter, i would like to try that if you can upload it somewhere. I tried uploading some third party firmware in the meantime and while those flash successfully, the power light still blinks and i can't get an admin page.

    nreiter, you are a life saver. The new 4.21.4 firmware ruined my Linksys WRT54G. Many people are having this problem.

    I reflashed with the image you've provided (after unzipping it) and now my router works once again. Thank you!

    Linksys does not provide the 4.21.1 firmware from their web site. I contacted support but they told me the firmware is no longer available. I believe your file may be the only file available anywhere on the internet.

    Glad I could help. Hang on to that file!

    Now if I could only unbrick my router :(
