    Hi to all the lost routers out there,

    if you can't ping your Router anymore and you can't upload a clean firmware via tftp, try the this method for above described model.

    When the really great WRT54G Revival Guide Tip #2 failed to debrick my WRT54GL v1.1 with a MX 29LV320CTB Flash chip, now here the solution without soldering that worked for those Flash chips:

    1.) open a command prompt and type "ping -t -w 10 [Enter]
    => ping starts running

    2.) open a second command prompt and type "tftp -i PUT

    3.) unplug the power cable of the router

    4.) take a small screwdriver and shortcut ping 16 and 17 (press it firmly
    between the pins)

    5.) plugin in the power cable while pin 16 & 17 is still short cutted

    6.) wait in this "position" about 3 seconds

    7.) remove the screwdriver from pin 16 & 17

    8.) wait 2 seconds

    9.) have a look at command prompt 1 => ping should be OK now

    10.) press enter in command prompt 2

    11.) good luck ;-)

    I bricked my WRT54GL v1.1 after upgrading with the wrong firmware. It is true, shorting pins 15 and 16 didn't work for me. It was fixed when I shorted 16 and 17. I used a magnifying glass and the smallest flathead screwdriver I had. My power cable was connected between the router and a power strip with a circuit breaker. This way I could turn it on/off with my foot, and use both hands on the PCB.

    So, while my pc was pinging the router, and the screwdriver was shorting pins 16 & 17, I turned on the power. Exactly two seconds later (still shorting the pins) I saw the successful ping with TTL=100, at which point I removed the screwdriver. Then I used tftp.exe to flash the router with original Linksys firmware Ver.4.30.15. TFTP.exe needs thr default password of the router "admin".

    I am glad that at least shorting 15 & 16 didn't make things worse.
