Maybe helpful info for Linux users... I managed to debrick the WRT320N using a Nokia DKU-5 cable, USB TI 3410/5052 Serial Driver (module in the Linux kernel), CuteCom, and atftp (no linksys password needed).
Cheers!
Can you post which pin are TX, RX & GND?I will try to fix My brick TP-LINK router with it.
pin 1: not on connector!
pin 2: GND (white on my cable)
pin 3: not needed (yellow on my cable)
pin 4: V Out, probably not needed; 3.3V (green on my cable)
pin 5: not used
pin 6: RX (red on my cable)
pin 7: TX (blue on my cable)
pin 8: not used (but could be GND instead of pin 2)
pin 9: not used
pin 10: not used
pin 11: not used
pin 12: not used
pin 13: not used
pin 14: not used
I didn't solder, but pressed the wires to the board using a match and a wooden clothespin.

This picture shows the WRT610N, but looks similar to the WRT320N. I attached the wires in this order (top-down): green, blue, red, nothing, white. Use of CuteCom is like HyperTerminal in above thread. The command for atftp is somewhere in the Wiki.
Good luck!
Here is a reconstruction how I debricked my WRT320N... (from my memory and a found command log)
- Remove power from the router, connect the router to a computer using a network cable and the usb-serial converter.
- Install/load the drivers. Windows: from CD or driversguide.com or something; Linux: modprobe usbserial and ti_usb_3410_5052. My cable has a Texas Instruments chipset: TUSB3410 Microcontroller.
- Start a serial console (like HyperTerminal on Windows, CuteCom on Linux). Read on here what settings to use:
http://www.dd-wrt.com/phpBB2/viewtopic.php?p=254820#254820
- Connect power to the router.
- During router booting: hold Ctrl-C from the start, to get a command prompt, release when you see:
Code:
CFE> ^C
CFE> ^C
CFE> ^C
CFE> ^C
...
- In the serial console type:
Code:
CFE> nvram erase
CFE> reboot
- During router rebooting: hold Ctrl-C to get the command prompt again.
- After router reboot, prepare it to accept the firmware over the network cable:
- Not sure this nvram erase and reboot is needed, just in case. In the serial console type:
Code:
CFE> nvram erase
CFE> reboot
- The router reboots, but we still have to erase nvram one time... hold Ctrl-C to get the command prompt again.
Code:
CFE> nvram erase
CFE> reboot
- The router reboots from the new firmware, check if you see "DD-WRT login:" in the serial console, at the end of the boot process. HURRAY!!! I guess you debricked it!
- Shut down serial console, disconnect power from the router, remove cables, revert networking to dhcp on your computer
[1] Update 2010-12-14: Don't use the Router Database anymore, but get the current recommended firmware version here:
http://www.dd-wrt.com/phpBB2/viewtopic.php?t=52043, click on the link after "For models that REQUIRE the K26 build (like the WRT610nV2, WNR3500L, RT-N16...etc...see note above)" and download the image with a trailing "_wrt320n.bin". _________________ May 2022: Got a Linksys E2000 from my brother!

Thanks for the post here, I managed to get my WRT320N back to work. :)
Two things to share:
1. the 5 pins on the board are:
pin 1 vc+
pin 2 tx
pin 3 rx
pin 4
pin 5 gnd
2. when you got connected, try CFE>nvram -erase first.

The topic title mentions "pin short", which is not recommended to do. I read somewhere that it may harm the hardware. I did a pin short several times, before buying an USB cable, because that would be the easiest thing to do. It didn't help, but didn't harm either in my case (everything works fine again). The Peacock Thread says to try USB debricking first! _________________ May 2022: Got a Linksys E2000 from my brother!

The "pin short" discussed in this thread, is not really a pin short. Around the processor there are a few "tp's" (test points). One is gpio6 which is the reset button. It is just like pushing the reset button but on the 320, the reset button does not work. Gpio6 does. It is not a "pin short" that shorts pins on a flash chip.
Problem with shorting gpio6 on this device, the tp's are very small and close together. It is easy to short the wrong tp if you are not paying attention. _________________ [Moderator Deleted]

So I've soldered on the appropriate wires 3.3v, gnd, rx and tx. I accidentally hit one of the wires and it lifted the copper pad off the printed circuit board (it was RX or TX, cant recall). I'm afraid I'm screwed. Is there any other point/pin on the printed circuit board I can get access to RX/TX to reprogram this?
Hi guys, i was wondering if you guys were using a serial ribbon cable in conjunction with the nokia cable to debrick your routers?
I'm thinking about getting the Nokia CA-42 USB cable which is alot cheaper and fast uk delivery. The guy in this tutorial used it to upgrade his router from wrt320n to e2000: http://www.mi-computersupport.de/index.php/tutorial
Do i actually need a serial ribbon cable inbetween the nokia cable and the router or can i connect them directly?
If you guys did you a serial cable could you attach a photo of how you did it.
Anyone know if the nokia drivers work (http://europe.nokia.com/support/product-support/cable-drivers/driver-for-nokia-dke-2-dku-2-ca-42-ca-53-ca-70-ca-101) on Win 7 x64? I'd prefer not to have to use a linux live cd.
I have a bricked wrt320n which is running E2000 CFE. Anyway on this cfe tftp on boot does not work. It is uploading successfully but no go after that so I'm going to serial flash it.
I have DKU-5 cable but I really don't want to cut it so I will try to just tiny wire the other end. Anyway I need to know which pins on the cable are the ones I need. I've saw the posted information about 14 pins but every time I count it I get only 13 so I guess that info for this cable is different...
Could you please point me to correct pins that I need to use?

Yes these, on the underside of the board. Not sure from here how you're going to get outta cutting the cable, these aren't standard 'pinout' style serial port here.

13 is correct. Pin(out) 1 was not on the connector in my case, and a few contacts of the connector without any wire. So pin 2 of the Russian schematic, is the first contact on your connector, if you don't hold it upside down.
Merge pinout 2 and 8, because you can't see which one is wired. _________________ May 2022: Got a Linksys E2000 from my brother!
