Hello,

I have bricked WRT54GSv2.

http://www.dd-wrt.com/phpBB2/viewtopic.php?t=1264

I tried easy ways to bring it back to life but with no success yet. It does not respond to ping.

Now I can either crack it open (void warranty) and try to short-circuit pins, JTAG, etc. or just RMA it to Linksys as it is right now and get a replacement.

If I do RMA, I do not know which model they are going to send me back. From reading the forum I understand that it is not always true that later version is better. Some cannot be flashed with dd-wrt for example.

What is the common wisdom here: debrick or rma? If rma, which particular h/w versions I should try to avoid or try to get if I give up my current WRT54GS V2.

Thanks

Debrick! (JTAG)
You'll never get replacement router with 8MB flash and 32 MB ram. (You'll get 2 /16 in best scenario)

That's one of the best models -- don't send it back !

Just try the pin-shorting trick - it only takes a few minutes.

I've done this dozens of times

here's some tips --

1) I always set my computer's IP to static - it won't be able to pull a dhcp assignment from the brick.

2) I use a hub between the pc and the router to avoid delays in the pc's ethernet initializing -- If you can't do that, set the ethernet port to 10Mb/HDX so it doesn't waste precious nanoseconds auto-negotiating with the wrt port.

3) I keep continuous pings to 192.168.1.1 running in one window, and have the tftp transfer all queued up to start in another, and I focus on this tftp window.

4) I tape one side of my wire to the flat top of the antenna port so I can hit the pins on the flash chip with the other end using one hand while I power up with the other hand.

5) I move my "power hand" to the keyboard. As soon as I see the first ping response from the wrt with the TTL=100, I start the tftp

I sometimes have to repeat 4) & 5) to get the timing just right, but I've always been successfull.

Agreed... I bricked my new v4 the first few minutes I had it. I hunted through the store shevles and found the only v4 left in a sea of v5's so there was no way I was sending it back. After a few minutes I calmed down, cracked it open, shorted the pins and it has been working fine ever since. It isn't that hard if you follow the directions as you should.

Thank you all. Collective knowledge indicates debrick, so be it...

Linksys revival guide http://www.linksysinfo.org/modules.php?name=Content&pa=showpage&pid=33 is sommewhat outdated and stops on GSv1.1.

Can someone who already successfuly debricked WRT54GS V2 confirm
that I should be using

pin 5 and pin 6 to for tip #2 ,
antena "earth" and pin 6 for tip #3 ?

I have successfully debricked my wrt54gv4 using the step listed in the link. Nothing worked for me until I shorted the pins on the flash chip and it then went into diag mode, applied my firmware and all is well.

btw, RMA'ing devices due to applying a 3rd party firmware or moding the thing only pushes manufactures to lock down their devices. It’s like adding a supercharger to your car and complaining to Ford when it blows up for an exchange. I change my wrt54g’s knowing that if I screw it up, I either fix it or buy a new one rather than ruining it for everyone else.

Just my 2 cents..

I found that tip #2 was incorrect for my WRT54GS v1.1. I needed to short pins 15 & 16.

Hope that helps.
