Hello guys i will appreciate it if you help me.

I decided to install DD-WRT on my TP-Link TL-WR940N.

And i think i installed the wrong firmware for the device maybe it doesn't match with the hardware version i don't really know :S.

Now everytime i plug the Router into electricity only the PWR Led light keeps runing and nothing else and when i plug an Ethernet cable the LAN 1 led runs (Not blinks just runs) ..

And i tried doing everything (pinging, changing IP's TFTP, nothing is working .. )



P.S Thanks in advance Smile

If you have the ability, you will likely need to use JTAG serial recovery

http://wiki.openwrt.org/toh/tp-link/tl-wr940n

This shows how to use PuTTY etc to recover

Did you use the right ip address for connecting to the router gui, 192.168.1.1?
Wrong firmware is not possible for a first time flash with the factory-to-ddwrt file uploaded to the TP-Link gui firmware update page.
It is possible to upload the wrong file to a router already running dd-wrt though..

Well that was my problem i firstly Flashed DD-WRT it worked ok but then i flashed the firmware again but another version so i think that's the thing that bricked it Sad

If you can do a 30-30-30 and get to the bootloader, you might be able to reflash the unit. Otherwise the JTAG method is the only thing I know of that's going to work.

I tried the 30-30-30 reset method a couple of times and again no use.

The JTAG method is a bit complicated and i couldn't find any good guides for my specific model.

Even if i manage to get the JTAG method to work i can't get the actual tjtag app because it needs a donation and in my country we can't pay online we don't even have PayPal accounts :/ it is not supported Sad

Any last resorts .. ?

Forget about JTAG, there are only very expensive commercial JTAG software for Atheros cpu's.

What you need to do is a serial recovery using either an RS-232 <-> TTL 3V serial converter or a USB <-> TTL 3V converter like the Nokia DKU-5/CA-42 cable.
3 wires (Rx, Tx, and GND) connected to the internal serial port of the router and the USB side connected to your computer (or the RS-232 side connected to a serial port on your computer if you choose that type of converter).
With this you can connect to the routers bootloader via a terminal program like puTTY running on your computer and tell the bootloader to listen for a tftp transfer on the LAN port. You will need to have a tftp program like tftp32 running on your computer for this transfer.

Refer to the dd-wrt wiki or openwrt wiki for Serial Recovery.

Thanks for the reply Smile, i read the DD-WRT wiki regarding Serial Recovery and it stated that if the boot-loader is corrupted than there's no use of using this method .. ? Is that right .. ? How do i know if my boot-loader is corrupted or not .. ?


And another thing i have a CA-53 Nokia cable will that work .. ? And the bundled cable with Nokia X6 the micro USB cable it doesn't write it's type will that work .. ? Which one should i use .. ?


Thanks in advance, and i really appreciate your help ..

The bootloader is usually not corrupted by wrong firmware loaded via the gui.
CA-53 is a USB to USB cable, it does not have a USB to Serial chip inside so it can not be used and neither can cables for modern Nokia phones, they are all USB to USB.

DKU-5/CA-42 can be bought in China (Alibaba or similar, or Chinese Ebay) for next to nothing.
They are 3USD from Ebay or Amazon in the western world.

No pin shorting can never fix a wrong firmware flash.
Your only options are serial recovery or throw away the router, nothing else.
