Bricked Router

Yakooza · 02-09-2009, 08:14 PM

Using a Linksys WRT54G, v.3.

I tried to install DD-WRT firmware and it bricked my router even though it said "upgrade successful!".

I tried every free method possible. It seems my router is completely unpingable and a hard reset won't work. (It doesnt even seem to do a reset. Lights dont change, nothing happens) As last resort I ordered a Jtag cable. I would like to retry the "shortening" method again though. Could someone explain what "short pin 15 and 16" means? I have trouble understand that so I just mashed the pins instead.

Luckily there seems to be no harm done.

Also, I am able to access the internet even when connected through the router. I still cant access 192.168.1.1 though. The problem I have now is that when I connect two computers to the router, I get an error on both telling me there is an "IP address conflict with another system on the network". I suppose the router cannot assign new IPs in its bricked state? Any way around this until I get my Jtag cable?

It sounds like maybe you've got your PC set with a fixed IP of 192.168.1.1, which is presumably the router's IP.
Check that aal computers are set to pick up an IP address automatically, by DHCP, and see what happens

Yakooza · 02-11-2009, 06:12 PM

Nope, I changed the Ip to .2...

Interestingly, it seems my default gateway has changed! It seems to be 169.254.196.56!
But I can only get a ping from it if I dont set a static IP. (otherwise, my Ip is 169.254.196.56 as well so pinging my own IP is sure to get me results...) Im still not able to ttfp though.

Yakooza · 02-11-2009, 09:03 PM

I just remembered that a 169 addy is not valid and means the router was not able to assign an IP

jcidiot · 02-11-2009, 09:08 PM

smart laddy. for the two computers problem, try manually setting ips; ie, pretend the router is just a switch.

try reflashing.

**bilbus** · 02-11-2009, 11:30 PM

169.254 = the workstation was not able to find a dhcp server, and give it self an address.

Yakooza · 02-11-2009, 11:39 PM

I tried setting IPs manually.

And how can i reflash if I have a bricked router and tftp does no work?

You'll likely require the JTAG interface connection if you've really wedged it.

Yakooza · 02-18-2009, 07:21 PM

Ok I got my JTAG.
No idea what to do now.

Instructions say to solder the pins of my JTAG cable to the board?? Someone please explain this?

**Snoopdogie187** · 02-18-2009, 07:55 PM

Hi, well this is the more mechanically inclined part of the job. You have to open up the casing, and get to the bored.

On the board you will have to find the points that the jtag cable attaches to. It should be online someone or maybe in with your instructions. On these points you have to attach the cable ends to it so that the ends don't come lose in the middle of using the jtag cable.

Soldering is the process of heating up solder (kind of like a metal) and using this melted metal to bond two things together. It does take some pratice (I have done it a few times and I am still tying to get to know it better). You do have to be careful, you can get a nice little burn (you have to heat it up to 400 degrees F, I think).

This is the quick guide to it. If you need to know more, let us know. You might want to find someone to do this part for you, maybe a friend who might know how to do it, or you might want to try it yourself. You would need the solder and soldering iron to do this. Not that much to go buy a cheaper one (Its not like you would be using it too many times probably).

Yakooza · 02-18-2009, 08:07 PM

I have used soldering irons since I was 5 and have gotten burns before (dam my curiosity).

Im just wondering how I would be able to remove the cable(when Im done) if I was to solder it.
Can't I just use tape? xD

**Snoopdogie187** · 02-18-2009, 09:26 PM

Well you have to unsolder them then. It isn't too hard to do, you have to melt the solder on there again and get it off. The make a solder wick for this reason I think. I would the suggest re-doing that point you jst took the solder off of. It is a lot of work/time to do all of this, but not too much.

You "could" use tape, if you do (at your own risk - I wouldn't recomend doing this at all) let us know how it went. lol I sure do hope you have some strong tape

**johnwill** · 02-19-2009, 11:29 AM

FWIW, the right way to connect the JTAG cable is by soldering the pins on the PCB and using the plug that it comes with. This will allow you to simply unplug it when you're done and save it for the next time.

I dont think I understood what you said. The plug?

**Snoopdogie187** · 02-19-2009, 05:40 PM

Yes the plug, one end of the jtag cable should be wires you attach to the board, the other end should be a plug that goes to your computer.

Yakooza · 02-19-2009, 06:50 PM

Ahh.
What got me confused is that he mentioned that I could "save it for the next time".

Lol I got scared because this computer doesn't have a parallel port. Luckily my older computer does.

Could someone give me a guide to it as well?
I havea Linksys WRT54G v.3

Yakooza · 02-19-2009, 08:13 PM

Ok ehh loaddvr now says that "service does not exist" when clicking on Start. (I clicked on Remove :-$) I put up giveio.sys again into the drivers directory and still same message!

Blah.

While it was working I was able to detect my chipset using wrt54g -probeonly in command prompt. This was only twice though. Most of the times it didn't work. I guess I will have to solder it to get a stable connection

EDIT: Nvm. It seems it can only detect my chipset when I apply loads of pressure on it. It starts to clear the Watchdog. How long does this take? My fingers get tired pushing it down after a while.

Ill consider soldering. But how? My instructions tell me to make "headers using a soldering iron". I have a soldering iron but how the hell do I do this? :)

Btw, there are minor holes on my pins(from the pressure) :)

Yakooza · 02-19-2009, 09:17 PM

Ok sorry for the triple post (although Im wondering who the hell actually cares about post count).

It seems my Jtag cable came with headers. I find them unusual though. They are stuck to the pins.

Pictures:

How do I solder this?
