    Hi Guys,
    yesterday i have flashed my wrt54gs from V23 15.09.2005 to V23 20.09.2005.
    After flashing, i can't surf in the internet anymore and can't access the router (yes i have flashed with "set settings to factry defaults").

    Now i can ping the router for ~10 seconds. After that i get an error (timelimit). I've tried to tftp flash it, but i have no success cause it says "invalied password". So i've taken a tftp with password.
    But then the error: "wrong pattern" appears.

    I've a 54gs V2 and i've take the right firmware (dd-wrt V23 mini 20.09.2005 for GS)
    When i use the dd-wrt V23 mini 20.09.2005 for G the message don't appears. But cause i can ping my router only about 10 seconds the tftp process doesn't finish...
    so what can i do??

    this is normal since the v23 like all other dd-wrt firmwares are internal handled as G firmwares. so the normal tftp does also work like a g unit. but the cfe unbricking tftp is still gs.

    cfe is the bootloader which is started before the firmware. with this bootloader you can unbrick a wrt also if the firmware itself is damaged or the flash has been failed

    ive alot unbricking success with the following procedure:

    At first get WRT54GV3.0_3.03.6_US_code.exe from Linksys

    1. Do a hard reset (30 sec reset button + power cycle)

    2. Switch ur Laptops IP to

    3. Set the Network Card to 10 Mb Half Duplex <--- this is very important

    4. Start the Linksys Tool and flash the original Firmware

    5. Do a hard reset again

    Thats it

    Ive used this procedure many times and it fixes all bricked issues.
    Yesterday again, i recognized that if u have set ur Lancard to automatic or something else as 10 Mb Half Duplex the tool is running also and says successfull upgradet BUT this is wrong the router is still bricked ! As soon as u drop ur lancard to 10MB Half Duplex, flashing again, the router gets back to you !
