    Hi, I bricked my linksys wrt54g v3 during a firmware upgrade.

    It is non-responsive to pings. My power led blinks, and another led is lit showing the connection to my laptop.

    To get ping working i have to ground out flash header pins 5 and 6, or the antenna and pin 6 or 16. Any of these will give me ping responses... but i get a timeout error while trying to tftp a new firmware.

    I searched a long time for a version 3 model, now it's bricked. If anyone can help that would be great.

    when you tftp to the router areyou doing this straight away as the router ispowered on? you have about 5 seconds to get the firmware sent. thats why it is recommended that you use the micro version of ddwrt since it is very small.

    you need to have the tftp util ready to send the firmware to the router, and power on the router. as soon as the power is turned on click upgrade.

    Hi. as soon as i plug in the router i've tried this.

    I send the firmware from the cmd prompt ie: tftp -i PUT <firmware name>
    it gives me the error "error on server: code pattern incorrect"

    or other times I tried the upgrade program from linksys and it says "no response from server".. or it sits on the "erasing flash screen" forever.

    Any ideas ?

    Sometimes debricking can be tough, I have ran into a few that were a bear.

    My experience is that if you can get a ping, you can flash. In some cases I had to resort to the standard linksys firmware for the recovery. (for some reason 3rd party versions would not recover a brick, maybe it was just a fluke).

    I have always used the linksy tftp at boot.

    ok, so do i have to ground out the pins to do the frash upgrade, or just plug it in and start flashing ?

    both methods are giving me "no response from server". When i do ground the pins, it only takes about 2-3 seconds to start seeing ping responses.

    Ahh..... "code pattern incorrect" try using the generic micro firmware

    Toasted my V1 a few weeks ago attempting to flash from DD to Tomato. :(

    She won't stay responsive long enough to reflash. I can sometimes get a coupe of replies..then back to nothing.

    Ah well...ran a long productive life.

    Is there nothing i can do ?

    I can get a ping reply everytime, if a ground out the pins.

    Does anyone repair them ?

    Update on mine.....I finally sat down and gave it some serious effort.

    I downloaded both the mini-DD, and the full Linksys setup utility which includes the firmware built in.

    Tried grounding out pin 15-16, and 16-17.

    My replies only lasted from 4-6 pings...then she'd go non-responsive until power cycled again, or I repeatedly hit the reset button quickly for about 10 times. Then it would reply only 4-6 times again..and go unresponsive.

    Many attempts to reflash with any DD or even default Linksys .bin files using tftp failed.

    I grabbed the Linksys setup utility again..and it managed to grab hold of it long enough to push the flash up. I had to power cycle the router to be able to log into the web admin.

    Logged in..showed at wrt54gl Heh...

    Power cycled...flashed through the web admin with dd-wrt. Took 2x power cycles to be able to log in.

    NOW...the Tomato website is saying don't attempt to flash v1 with tomato. :D I don't recall seeing it when I tried a few months ago...ah well.
