Sorry for the shameless bump, but could anyone help me out in my thread I made at: http://www.dd-wrt.com/phpBB2/viewtopic.php?p=186697#186697 ? I Have this particular Linksys router and am having huge connection issues with my wireless Xbox 360. Thanks.

Well, I bricked my router. When I power it up, I get 4 ethernet and Internet lights on solid, no power, no wireless. Can't ping the router. I have a JTAG cable, and I can issue commands to it via the tjtag utility. I seem to be able to -erase anything, but I can't seem to -flash anything. Flashing starts, but takes LOTS of time to even get thru the 0% marks in the updates.

I assume that, since I can get to it via the tjtag tool, I've at least got a chance at de-bricking it?

I do have the 2 samsung chip version, not the EON version.

Any suggestions would be most welcome!

What version router, and what are you trying to flash ?

If it is a CFE or BSP, try using the switch

tjtag -flash:cfe /noreset

This command needs to be issued right after turning on the router, it may take a few tries to get it right.

It's a WRT54G V8. I've tried to flash ANYTHING to it. I've tried letting CFE run overnight, It seems to get to about 4% and hangs. I've had similar results with KERNEL, CODE and WHOLEFLASH, all created using the backup tool (from after the router was a brick, unfortunately). Should these backups be good to use? Or should I try to find known good ones elsewhere?

I don't think I tried issuing the -flash immediately at startup, I think I've always had the thin powered on for a bit first. I'll give that a try, thanks!

EDIT: Well jtag -flash:nvram /noreset has been running for about 3 hours, and only to 6%; seems REALLY slow, is this normal?

EDIT: Well, it's been over 12 hours, 22%, this can't be normal...

This process ALSO works with the WRT54GSv7 with only a little HEX modification to the vxworkskillerv8!

*Of course, you'll have to reset the router to factory defaults before flashing*

Here's what I did:

1) Log into the WRT54GSv7.
2) Under the Administration tab, RESET TO FACTORY DEFAULTS.
3) Go back to the Administration tab [192.168.1.1].
4) Firmware Upgrade via the Linksys GUI vxworkskillerGSv7-v3.bin
5) Update will be successful.
6) Manually configure your Network Card to a manual IP something like 192.168.1.77, then Manually configure Gateway to 192.168.1.1, DNS to 192.168.1.1
7) Hold down the RESET button on router for 30 seconds.
8 ) Wait about 30 more seconds, then unplug router.

9) HOLD DOWN reset button, then plug-in router. Then release reset button after 5 seconds.
10) QUICKLY Open command prompt, and use TFTP command:
tftp -i 192.168.1.1 put dd-wrt.v24_micro_wrt54gv8.bin
11) You will see the activity light on your network indicator "go crazy".
[[If #11 doesn't happen AND you get TFTP TIMED OUT, I had to repeat step 9 then 10 to be quicker]]

12) Wait about 10 minutes, and the TFTP should acknowledge success.
13) Log into DD-WRT Router!!!!

Thank you BrainSlayer + Tornado!!! I just slightly modified your VXWORKS .bin to work this way, too!

GRRRREAT!


Thank you very much.

Just what the doctor ordered.

Work perfect.

In case this helps anyone, I followed the instructions here:

http://www.dd-wrt.com/wiki/index.php/How_To_Flash_the_WRT54GS_v7

I followed the instructions in the section entitled "ALTERNATE METHOD TO FLASH DD-WRT ON A WRT54GS v7 WITH AN INTEL FLASH CHIP". I'm still not sure if I have an Intel version or not, but it worked perfectly on the first try. My serial no. starts with CGNC1 and the date on the other sticker says "07/2007".

Good luck!

I have very little knowledge of computers, but after reading this forum I thought I would give dd-wrt a try on my wrt54g v8.00.2. I am using vista home premium if it matters? First I went into explorer and cleared all cookies etc. Then I went to 192.168.1.1 I flashed vxworkskillerGv8-v3.bin I got a message saying to reboot. I unplugged to power cord, plugged it back in and waited about 5 minutes. Next I tried to flash the dd-wrt version dd-wrt.v24.micro.generic.bin.
I was asked for servor, password, and file. I was not exactly sure what to enter for server, but I entered 192.168.1.1, I left the password blank and browsed to the ddwrt file. All I get is the error message "erasing flash this may take several minutes". "Unable to resolve host address." I am not sure if I set my lan ethernet address right. Could this be the problem? How do I set this?

Hi,
Just wanted to say THANKS to BrainSlayer and all guyz who contribute to this website. Smile
Currently I am doing some project / coursework for my BSc course and part of it is concentrated around wireless router hardware.
Great work !!!
Maybe someone will find it useful...
I had some problems with
"tftp -i 192.168.1.1 put dd-wrt.v24_micro_wrt54gv8.bin
tftp: can't read from local file 'dd-wrt.v24-micro_generic.bin'"

and had to remove first "." and change the filename to file.bin without any extra dots and then it worked !

Take care guys
Konrad

I have a WRT54GS V7, now how do I tell what chip I have or does it matter. DO I just flash with instructions above. If not could someone show me the exact instructions to use. Thanks much
