DDWRT Bad Flash HELP PLEASE!

bigalexe · 05-29-2008, 01:19 PM

I tried and failed to load DD-WRT onto a Linksys WRT54G router. I read the help page for Recovery from a bad flash but it isnt helping me. I can plug in the router and I dont get a power light, the light that indicates a network cable does work. When i plug the router into my computer it says connected but i cannot ping the IP 192.168.1.1

Any help at all please!

If it helps, if i go to the Windows command line and try to ping the router i get a message that the destination host is unreachable!

You might have to reprogram the unit via JTAG. Have you tried all of the revival methods?

What is a JTAG, where can i get one? I read the article i could find and am still somewhat confused.

As i stated prior... i cannot ping the router and the power light does NOT turn on, the only light on is the connected cable light or the internet light depending on where i plug in a CAT5, not Power, WLAN, or DMZ lights.

Google????
In a nutshell JTAG is an interface designed to program and debug embedded systems.

Did you read the information in the provided links? Which recovery method did you try?

It does sound like your router is "bricked" as the saying goes.

I tried using TFTP recovery, but the problem is that i cant transfer data to the router at all since i cant even ping it. So i think i need to open it up and use the hard reset on the inside. I downloaded the Linksys Un-Bricking Tool for use with the JTAG protocol but am a little confused still about where i can obtain a JTAG connection cable. I want to get the cable and make sure i can use it before i do alot to open up the router itself.

"but am a little confused still about where i can obtain a JTAG connection cable"

You usually make one up yourself. The JTAG specification is open, so you can find information on it, expected voltage levels, etc. There are also probably numerous 'JTAG programming interface' kits from the likes of Radio Shack, although you have to do still more research to make sure it will work the way you want it to. For example, if you're running a Debian-based distribution:

apt-cache search jtag

How much is your time worth?

Something to consider given that this is only a $50 dollar device. I would suggest that your purchase a new router then try to fix this one in your "spare" time with your "spare" money.

Im going to buy a new router, but am also going to continue attempting to ressurect this one so i can load DDWRT onto it as a toy.
