Most probably you have damaged the bootloader section of the flash.
Can you please tell us what are the steps you performed before this thing happen ? It will be better if you can post the console dump before board crashed.
Please also check the power supply. It may happen that somehow high voltage is drawn to the board and it is damaged.

Unfortunately same things happen to me also. I have also added GUI into openWRT source code. After booting I have installed webif_latest.ipk by following command
opkg install webif_latest.ipk.
To do this successfully I have made small changes.
After that I am able to access web pages. However once I reboot the board it crashes.
I am now trying to setup JTAG so that I can reinstall bootloader.
Can you please tell me what did you do to install web pages ?

Hmmm, this seems worrying!!

I have installed X-WRT with no-problems at all, which makes me wonder what I did differently!

The bit thats confusing me is that I didn't install webif_latest.ipk but webif.ipk. I used the OpenWRT scripts/feeds to pull down the latest copy of X-WRT and add it to my source tree (edited feeds.conf). I then rebuilt the sources and added it to my running image. All of this worked with no probables what so ever.

What did you guys do that was different to this???

Ok well it looks like you have installed X-WRT for "White Russian" and not for "Kamikaze" (which is the version you would have built). So that explains the difference in the steps.

Unfortunately I have no idea why installing that version has caused the problem. I suggest unpacking it on another computer and checking what the install scripts and init scripts do. Perhaps it touches something it shouldn't.

Looking at the description of your problem you may well have to resort to using the JTAG to recover the board. Good Luck!

If you manage to figure out what happend, let me know!

I have not, as yet, had a chance (or a need) to go near the JTAG. I would be interested to know if you manage to get it sorted. The following link may well be useful:

I have the same problem. I don't know the steps that caused it, It's the first time I've used jffs and ipkg. (Without Input/output errors, anyway.) And I setup the sshd settings for the firmware dd-wrt.v24-11205_WGR614v8-L_mini.chk

When I set the sshd settings and the device rebooted I got the solid LED's and there is nothing on the serial console :(

Anyway, I'm looking into making a JTAG cable, also. Has anyone had luck with this method? Also, are there special considerations for making the JTAG cable, such as I/O levels, etc?

I did use dd-wrt.v24-11205_WGR614v8-L_mini.chk

It was my understanding that dd-wrt is built from the openWRT environment.
This firmware is the first I've found that allows jffs to open and work (I tried by: "touch /jffs/test")
Once that worked I did "ipkg update" and that completed successfully.
Then I looked at the packages that are in the system "ipkg list"
Then, to try the install system "ipkg install microcom"

Finally, because I was planning on using the serial port as an input instead of a console I setup sshd through the web interface. When I clicked on save and apply the router rebooted into a brick.
The symptoms are the same as listed here: all the LED's are on, dimly and there is nothing on the serial terminal.

My hypothesis is that, as I've heard elsewhere, the bootloader code is in serial flash. When I used the jffs partition I must have overwritten that code. Now, I'm in a situation where I have to get a bootloader back onto the board.

It is frustrating that the only option I have for adding functionality appears to be building a whole new firmware image. I REALLY don't want to spend the time building a cross-complication tool chain. I have other things to do with my time. ;)

Hi
I had similar problem before. WRT54gsv4 - No LED no ping - brick. I managed to make it work by shorting the 16th pin circuit on the chip. I even uploaded openwrt firmware (without gui) I do not know how to log in or change anything without GUI. I have the Talisman Firmware ready to upload, but just can't get in. I can ping it and I also see wifi signal. Any ideas how to LOG IN and CHANGE THE FIRMWARE? THANKS!!

you can upload your firmware through tftpd also but for that you need to access board's console .... do you have this set up at your disposal .. if yes you can do it through tftp ...

VASH said: Well I have uploaded the first firmware this way, but it seems that I can't do it again.     

If you are able to access board's console, then firmware upgraddation is simple. The steps are :

1. Press ctrl +c while booting the router - the router will give you the
CFE prompt.
2. start the tftpd server by running the 'tftpd' command. It will now
listen for the tftp packets.
3. Connect a linux host with the LAN side of the router. You need to use
straight cable for that.
4. Set the IP of the ethernet interface to 192.168.1.111 (can be
anything except 192.168.1.2 in the 192.168.1 subnet)
5. Run the following command from the host
    'tftp -m binary 192.168.1.1 -c put <FILENAME>'
