Bricked TP-Link WDR 4300 Router Recovery Using UART Serial Converter Part #1

[@hlipp1656]

Good video. I managed to install dd-wrt firmware on tp-link wdr3600 routers thanks to your movie. So thanks for that. The difference is I used an arduino uno (imitation model xdrduino uno) as sort of adapter. The rest of the procedure was the same. I did notice the tx/rx sometimes work if you reverse them suddenly :). These wdr3600's are basically dual band i guess, 2 antennas anyway. But excellent routers in overall performance, especially with third-party firmware that improves it more. The arduino is easily modified to a usb serial adapter. The ground pin and reset on analog side can be connected with a cable, then you use the rx/tx and ground to connect same as in your video. So it bypasses the programmable chip (atmega) and (with ftdi drivers) becomes an effective adapter for this purpose. Just saying for anyone who doesnt have a cheap adapter you used, in the Netherlands i could not order the amazon product you linked to. Only US or something. But your movie was really most usefull, so thanks for putting it on youtube, actually usefull stuff.

[@richardlloydusa]

You are welcome. Best of luck to you and thanks for watching. I appreciate the feedback.

[@richardlloydusa]

Ognian Lipnichanski I am not sure where your comment went but I will answer anyway. I created the bridge to make sure that the voltage was set to 3.3V as 5v will fry your router. I know I did not connect VCC or ground but I did not want to take any chances. It only takes a minute or two to do it. Better safe than sorry. Thanks.

[@okaramfiloff]

Thank you, i will try this soon.

[@richardlloydusa]

Ognian Lipnichanski You're welcome. Please update us with your results. Thanks.

[@okaramfiloff]

Richard Lloyd I just bring my router back from the death. :) Thank you very much for this great tutorial!

[@richardlloydusa]

Ognian Lipnichanski That's great! Happy to hear of your success with this. Thanks for watching and commenting.

[@richardlloydusa]

***** The pins on the UART adapter are labeled. You can see that at 1:53 in the video. On the router side I used Google to find the pin outs. Thanks

[@itguy46176]

Richard, Thanks for the video. I was trying to debrick a linksys E1000 v2 after switching from Openwrt (no wifi for that build) to DDWRT (used wrong one). I was unable to get Putty to work, removed the red + wire, and used just the GND, TX, RX, which resolved the problem with Putty! Awesome!!

[@richardlloydusa]

Thank you very much.

[@RodriGonca]

Excelent tutorial ... I got in the same situation with my WR4300 and thanks to your video it is up and running again!!!

[@richardlloydusa]

That's Great! Happy to hear of your success with this. Glad it works for others. Mine is still functioning fine too. Thanks for your comment and watching.

[@iangraham6730]

I don't get the "tpl" part?? Why tpl if it's an unknown command?? Surely any character + enter would work? Or even just enter by itself? Thanks for sharing!

[@richardlloydusa]

TPL is short for TP-Link. Probably why they use it. Thank you so much for commenting and watching. I appreciate it greatly. All the best.👍😀

[@sergiogio]

Hello Richard! Just Wanted to let you know this tutorial worked perfectly! in the year 2020!

[@NeoPhyTex360]

Another one bricked with latest dd-wrt I unbricked it with your tutorial and a CA-42 cable. Thanks!

[@richardlloydusa]

You're welcome. Looks like it's going to happen to many people. Any beta build after r25974 DD-WRT firmware bricks it. Thanks for watching and the feedback.

[@AbdullahAtta]

Richard, thank you so much for your very detailed videos. I learned a lot from this video and finally got my router back to working again. My router is wr940n v5, it got bricked when I accidentally uploaded wrong ddwrt firmware. It kept rebooting over and over again. I was forced to take serial recovery path and in that this video helped me immensely.

[@richardlloydusa]

You are most welcome. I am glad to know I could help you recover your router. Thank you for watching, commenting and the kind words. I appreciate it greatly. All the best.👍😀

[@jhkcreates]

Thank you so much. I have another router but I couldn't find anyone that actually had to solder the pins on it and that confused me - now I know that this is normal and can be expected...

[@alanmcrae8594]

Great tutorial! I am gearing up to UART into a SONY DASH to see what I can learn and whether there are any possibilities for modifying it into a useful device of some kind. Your video was a good intro to connecting from USB to UART. Thanks for showing & teaching!

[@richardlloydusa]

You are most welcome. Thank you for watching, commenting and the kind words. I appreciate it greatly. All the best.

[@matefon2]

Thank you! Worked for WDR-3600 (v1) too!

[@richardlloydusa]

You're most welcome. I'm glad to know I could help you. Thank you so much for watching, commenting and the very kind words. I appreciate it greatly. All the best.👍😀

[@cominup85]

This is great, really well explained. I've become interested after reaching into openwrt. Didn't want to brick my router so bought an old one and going to do some learning! Thanks a lot.

[@2liveis2fly]

Great tutorial for the most part. BUt why would you use a steel paper clip (about 7:32 in vid.) for your pins? Probably be easier using copper wire of the right size, takes solder much better than steel. All-in-all, a great video tho!

[@LanceMcGrew]

Amazing video tutorial and detail. The effort folks like you put forth to help others is greatly appreciated.

[@richardlloydusa]

+Lance McGrew You are most welcome Sir. This one took quite a bit of research to get right but It also helped me save the router I currently still use and taught me much. Glad I could help. Thanks for watching.

[@peterchan3791]

my router is back to life. Thanks. WORKS!!!

[@richardlloydusa]

You're most welcome and thank you so much for commenting and the very kind words. I appreciate it greatly. All the best.👍😀

[@Ecsa0014]

I have exactly the same problem after trying to flash my WDR3600 with DD-WRT. I plan to try this fix as soon as I can get some header pins to solder onto the router mainboard.

[@richardlloydusa]

My paper clip pins were crude but they worked just the same. Good luck Sir. Thanks.

[@Ecsa0014]

Richard Lloyd I completely missed that you had used paperclip pieces for pins. Anyway, my header pins came in and, after soldering them onto the mainboard and following your directions exactly (except for using an Arduino I had lying around in place of the CP2102), My WDR3600 has been unbricked and is working perfectly. Thanks for taking the time to upload these videos, They were an enormous help for me.

[@richardlloydusa]

Branon Young You are most welcome. I am happy to hear that it helped you fix the router. Thanks for the kind comments, feedback and watching

[@aameralmutawa6171]

Thank you so much! I saved my archer c7 with your tutorial. Liked a subscribed

[@richardlloydusa]

You're most welcome. Comments like this make my DAY! 😁️ I'm glad to know I could help you and that you got value from my work here. Thank you for watching, commenting and the very kind words. I appreciate it greatly. All the best.👍😀

[@hafizullahsufi]

Knowing how to connect via serial interface is so very helpful. I was able to gain access to a Netgear router that I'd flashed with Tomato; the flash actually succeeded but somehow the password was munged and I couldn't get into the web UI. Access through the serial/USB cable let me see that the router was, in fact, booting correctly and I was able to "nvram show | grep pass" to see that the user password was a string of garbage characters and write a coherent password to the router right there, to be changed through the web UI once I got in.

[@felipeaugustodarocha]

Very nice vídeo! Amazing detailed explanations! I got my Netgear r8000 bricked and I couldn’t do anything, same symptoms, thanks a lot

[@woodsmith_1]

Thanks for this video. Nice to see it done successfully before diving in.

[@richardlloydusa]

You are most welcome. Thank you for watching and the kind words. All the best.

[@Algoth1]

I was almost losing hope. Great tutorial. Thank you very much.

[@richardlloydusa]

You are welcome. Glad I could help. It's too nice a router to toss in the trash. Thanks for watching.

[@GadgetReviewVideos]

Maybe this video should be called how to install DD-WRT on this router, because recover is a lot easier using the latest stock manufacturer firmware (auto erases memory). Someone probably already posted the TFTP IP it’s looking for in a forum, then you won’t have to buy a serial adapter. Maybe no adapter needed if someone else has already posted the TFTP IP Address for your router. I believe these routers start the TFTP server by holding down reset for three seconds when powering on. Most of the time eth0 might be the wan port of the #1 port on the 4 port switch side. Google the forums for your router made by this company and someone probably already posted the IP that the TFTP is looking for. Set your computer/TFTP server to use this IP that you find in the forums. If you download the official firmware, it will erase the memory in the beginning if the firmware install and no need to run commands manually. Now it will install the stock firmware, done and recovered. Now if you want DD-WRT on a router of this model that is bricked then you might need to follow his instructions. If you just want to recover it with the stock firmware then this is to complicated and not needed. I say it might be needed for DD-WRT since sometimes third Larry firmware use special images that are vulnerable to install the third part firmware.

[@Goryglory0209]

Amazing vid. I have a netgearR8000 and using the same dongle with Windows 10 drivers. I do see the router startup and all but I seems can't break the code running. Tried maybe 20 plus times now. Forum says ctrl c but that does not help. Any help ..thanks

[@richardlloydusa]

Try disconnecting the ground wire. Thanks

[@oqkeujdkrs5670]

Hello. Currently I have 841nd v8 brick, I tried to follow you, but putty can not connect to 841nd v8? The putty window does not show anything. Now, what must I do ?

[@robnmi1977]

hello, may i have a quiestion. I am typing tpl+enter right after the autobooting message...but the bootloop does not stops... what am i doing wrong?

[@richardlloydusa]

You may have a poor connection to one of the pins to the board. You may want to check the solder points and make sure they are making good contact. Thank you so much for commenting and watching. I appreciate it greatly. All the best.👍😀

[@meezangroup]

Dear Richard I tried your tutorial but I think in my netgear router the txd and rxd is bit confusing so I connected txd to txd and rxd ro rxd.. it did something and now the lights are not dancing.. neither it is in loop.. couple of light stay on all the time.. I identified the right pins and connected but I'm not able to communicate with the router.. Any solution you can think of?

[@raghunaththakar]

Do you have to solder the pins to router if they are inserted reasonably well and aren't loose?

[@richardlloydusa]

+Raghunath Thakar It might work if you don't solder them but I would recommend against it. Any movement or bad contact can cause noise and data corruption which could lead to a corrupted router. Thanks.

[@GadgetReviewVideos]

Nice job. You can turn in login with putting to output to a text file, this way you can read what’s going on and getter better messages, if it shows a hardware issue the restoring could be a waist of time. Are you sure your programmer isn’t marked wrong? The square pad on the PCB is usually always ground. That’s weird that This router wouldn’t follow the standard?

[@richardlloydusa]

It worked exactly as shown. Thanks.

[@MartinMarchev]

Thanks a lot for this helpful tutorial, Richard! One question - how do you solder the clips on the board?

[@richardlloydusa]

+Martin Marchev You are welcome. Here's a video on soldering electronics that may help kzbin.info/www/bejne/f6HOnJmBbphqo7c there are many KZbin videos on soldering that will help you with the task. Thanks.

[@marrohom5]

I wondered if that programmer could work with tp link n600 model, thanks for doing great and useful videos

[@mikeryan6650]

Thanks for your video. Can I use this method to rewrite the factory image back on the Rosewill RNX-N150RT?

[@richardlloydusa]

Mike Ryan Not sure if it has the same recovery options. This video is specific to this router. I don't have a RNX-N150RT to test this with. Thanks

[@mikeryan6650]

Thank you very much for your reply.

[@frankbarrera7935]

thanks +Richard Lloyd, I have a tl-wr941nd, too with infinity reboot, me question is, ¿believe can do it same?

[@richardlloydusa]

Have you tried this procedure: kzbin.info/www/bejne/ZpyUpKutjZqjg80 ? Thanks.

[@theblockk]

Hey Richard thx for this Amazing Lifesaver video, my question is if i can put the original tplink firmware instead ddwrt to debrick my router? Thanks you very much

[@richardlloydusa]

If you want to go back to the stock Tp-Link firmware I would use the default DD-WRT firmware (21061) to bring it back to life then use the webrevert.rar to bring it back to the stock Tp-Link firmware. Then I would download and install the latest stock firmware from TP-Link. It's the safest route. Thanks

[@theblockk]

Richard Lloyd The problem is that my router has not yet the Webrevert.rar from ddwrt. I have Tp-Link archer c9. Thanks

[@richardlloydusa]

Junior Vásquez Ruiz I was working on a solution for that on my TP-Link WR841N V9, which I have the same problem as you, when I dropped my screwdriver on the circuit board and fried it. I did order a new router because I love it and use it as a back up and DD-WRT range extending bridge too. I will make a video on how to return it back to stock. Hopefully the same process will work on your TP-Link archer c9. I should have it done this week sometime (depending on my success in doing so). Thanks.

[@theblockk]

Richard Lloyd oh Thanks, i'll be waiting for it!

[@richardlloydusa]

Junior Vásquez Ruiz Thanks.

[@wadj55]

I'm from Brazil, I'm messing with this one anyway, but I do not give the option to type commands in PUTTY, which key do you press to give the option to type commands? because in PUTTY all the time restarting without giving option to type something!

[@richardlloydusa]

Keep trying the stop command I show on the video and make sure you are connected correctly. Also try it with the ground connection detached. Thank you for watching and commenting. I appreciate it greatly. All the best.👍😀

[@AlfieChan]

Hi Richard. I, unfortunately, TFT'ed an official TP-Link firmware with the boot portion not stripped to my bricked Archer C7 v1.1. When I try to TFTP the correct, stripped firmware, it doesn't do anything anymore. So my last hope is using the serial connection method. I have an old PC lying around with a real serial port. Instead of a UART-to-USB converter, can I just use a DB9 serial cable, strip the wires on the Rx, Tx and GND and connect it to the TP Link Archer C7's serial connector as shown in your video?

[@richardlloydusa]

You can give it a shot but make doubly sure you do NOT connect any voltage leads to the router. Thanks and please update us on how it went.

[@experttutor1390]

Brother , How can use Modem Or any USB Hard/ soft drive ?

[@richardlloydusa]

Sorry but I don't understand what you are asking. Thanks.

[@pepepotamo2706]

Hi Richard. I will find a Nokia cable ca-42 or DKU-5 and will retry to unbrick de TP-Link. Kind regards.

Hi richard I am looking some help to flash actiontec gt784wn .isp locked the firmware update tab on isl custom firmware and i want to flash it with stock firmware .Could you help me for this please

[@nikpacara1]

Thanks for the video Richard! I was wondering how did you find out which pin is which on the router board? Cheers

[@richardlloydusa]

+nikpacara I found the pin outs on a obscure Russian site (Thank you Google Translate) then I verified them with my meter and a little trial and error with USB UART. Thanks.

[@shusterme]

hi man, can you help me? I have a bricked dlink 841n. I already have a USB-serial converter, driver is installed and all setup with putty, but no luck connecting. I get some wierd characters in loop. A leave you a url with a print screen: postimg.org/image/vop3pe09f do you have any idea what is going on? what is wrong? Speed is correct and XOR is disabled. thanks

[@richardlloydusa]

That looks like noise. Make sure you have all your connections correct, your wires are good, your solder joints are solid without any bridging. Thanks.

[@Techypy1]

sorry i mean i have a tl-wr841nd bricked and 941nd bricked also ?? can i do the same things ??

[@richardlloydusa]

Full chicken440 I have a video on how to recover the WR841ND without a serial connection here kzbin.info/www/bejne/ZpyUpKutjZqjg80 maybe the same procedure will work on your 941ND Thanks.

[@idf-iraq3375]

my problem is when i power on the router all lights or leds flashing at the same time excpet the power led stays on .... flashing all and in a second they turn off all and flashing again an so on>>>i am by mistake install openwrt to the roter and this happend to me ? what can i dp to fix this problem ???!

[@richardlloydusa]

Full chicken440 Have you tried my video on how to recover the WR841ND without a serial connection here? @0 maybe the same procedure will work on your 941ND Thanks.

[@lauraskipper6040]

I saw post after I had bought different connector which doesn't work. cam has power as it rotates but does not load boot loader. cannot get any commands with any software used. cam maybe trash. foscam will work with me as next to take a picture ro show how I have connected. They will try to work with me on this.

[@okaramfiloff]

Thank you for this great tutorial. I just bricked my router with the latest beta of DD-WRT 01-29-2015-r26081. I will order the same CP2102 module, but i feel confused. Why we need to make a bridge between GND and 3V3? You didn't use the VCC at all.

[@mihaisurugiu]

hi. i've accidentaly upgraded my tp-link ac 1750 with the wrong firmware. it's doing the exact same thing like the routter in this video. i can't connect putty to it. need somne advice. thank you

[@richardlloydusa]

Did you try the solution I have without the serial adapter first? kzbin.info/www/bejne/Z5m6hWZrrJumjKs Thanks

[@mihaisurugiu]

Yes. I've tried that and it send's the .bin file to only 89-90%, doesn't go 100%. Plus powering routter while pressing reset for 3 sec, the releaseing reset doesent do anything.

[@richardlloydusa]

I am not clear, have you connected the serial/USB adapter to the router? Thanks

[@mihaisurugiu]

Richard Lloyd no. I don't have one. Only through network cable. In order to get a log from tftpd program i have to keep the reset button until i see the log, where it's waiting for recovery bin file. I only get 90% of the bin file exported with the same result each time.

[@richardlloydusa]

Unfortunately it does not always work. BTW if you have windows firewall on make sure you turn it off and any other program that may block it like an Anti-Virus program and try it again. Thanks.

[@lukegrossotron8015]

ch341apro tem como fazer esse procedimento ?

[@TheMahdifarhat]

can i do the same with archer 2600 ?

[@jorgek.c.8766]

Eu tenho um tplink que ao enviar comando via ssh, acabei por gravar em uma pasta errada e apagou a memoria, ficando com os leds iguais a este. Com cabo serial e tenho 4 funcionando, nenhum faz a comunicacao com a memoria mesmo porque ela foi apagada e estes pisca-pisca dos leds se refere ao pulso eletrico do circuito para dar start na flash e como nao tem programa, nao é possivel o putty fazer a comunicacao. Lamento, mas isso nao é verdadeiro. Nao mostrou por completo ligando no router com problema e sim em um router que estava funcionando.

[@NiceGamerzX]

I connected everything and I can see everything in the terminal, but when I type tpl it doesn't stop rebooting itself. Is there any way to make my router stop rebooting?

[@richardlloydusa]

Remove the ground connection from the connector and see if you can get it. Thanks.

[@NiceGamerzX]

just disconnect the ground pin? or do I need to remove the bridge between the 3.3v and GND?

[@mecrayavcin]

Second question. With factory setting router has 192.168.0.254 login page 192.168.1.111 will work if i reset router? Or should i give and ip to router from admin panel or should i give and ip adress from network ip ipv4 settings? thanks

[@lamseuyoan-m123]

hi i have tp-link tl-wr940n v2.1 can you show me how to unbrick it ?

[@richardlloydusa]

+yean lam Try this procedure I have for the WR841N kzbin.info/www/bejne/ZpyUpKutjZqjg80 Thanks.

[@chin9529]

I am not quite clear about the 3.3V and the 5.0V... where did you measure these voltages? I have my UART and I can see there are 2 pins with one of them marked as 3.3V and the other one marked as 5.0V. When I measured them, they are supplying the correct voltage respectively... and I do not have the option to "short circuit" in order to select the voltage. Any clue?

[@richardlloydusa]

These UARTs vary in design so yours may not have the option. The whole reason for the switching of the voltage is to assure that if you mistakenly attach the voltage line (you should not be connecting to the router for this procedure as the router is being powered by the wall power supply) you don't fry the board. It's more of a safety thing than anything else. Just don't use it and you should be fine regardless. Thank you so much for commenting and watching. I appreciate it greatly. Subscribe, Click The Bell and stay tuned! All the best.👍😀

[@antony6268]

i have a dlink modem,done same method.but in putty it shows" press esc key to enter boot console" but esc key is not working.i tried various solutions in the internet but it doesn't work.please help me if you have a solution.

[@Techypy1]

what options I have to recover the router

[@frederickwinter1823]

when i turn on the router it just shows a bunch of jibberish theres nothing legible any ideas?

[@richardlloydusa]

More than likely that means you have a cold solder joint on one of the pins and it is making noise. Thanks.

[@felipemottan]

Hi! May I use a standard DB-9 cable and follow this tutorial by connecting TX, RX and Ground as instructed? Or it only works with this USB-to-UART connector?

[@richardlloydusa]

I do not have a serial connection to test with but you do. It will either work or not, try it and see but make sure you do not connect voltage and that if it does not work the first time reverse the RX TX leads. Thanks.

[@BoBB2000]

I have an serial connection , but getting only weird things on the screen, and cannot get an command line, My TP link must be pretty dead or corrupt.

[@AlexCVisan]

oh, thank you so much for this tutorial! I also got my wdr4300 bricked with a dd-wrt beta :( gonna buy a cp2102 and try this!

[@richardlloydusa]

You are welcome. It has saved mine a few times now. It seems that any beta build after r25974 DD-WRT firmware bricks it. Thanks

[@AlexCVisan]

Richard Lloyd and regarding bridging the 3.3V, I think that's only for the Vcc output of the module, so as long as you have no power connection between the CP2102 and the router's motherboard, I don't see a way of frying the chipset :-? is there any power through rx/tx I am missing? I'm asking because I just ordered a module like this one images9.okr.ro/serve/auctions.v7/2015/jan/02/a11bc61b18919800d9c55c5488a3c9d1-7354102-1000_1000.jpg which has two separate voltage output pins, a 3V3 and a 5V and I see no need for bridging any of these pins. Am I wrong? Thank you!

[@richardlloydusa]

Ciprian Visan You are probably right but what if you are not? What if you mistakenly connect Vcc? For the few minutes it takes to take the possibility out of the question why not do the bridge? If you do not have a soldering iron then I can understand your issue. Thanks.

[@AlexCVisan]

Richard Lloyd I just re-flashed my router successfully, thanks again for this video tutorial! P.S.: I finally used a PL2303 chipset converter and I didn't short the 3.3V output :) and as long as you don't touch the converter's output Vcc(s) (I had 2 outputs, one for 3.3V and for 5V) you don't need to short anything. Worked flawlessly! Thanks again! Cheers!

[@richardlloydusa]

Ciprian Visan You are welcome. Thanks for the feedback on the voltage setting. I appreciate that. I find that any firmware version higher than r25974 bricks my router. Is that what happened to you?

unbricking foscam fi9828P (not v2). cp2102 module shows only steady red light (not blinking), windows 10 does see in device manager on com 4 the module and I updated to latest driver; but plug computer and camera with Ethernet then powering camera tera term (using com 4 and same baud 9600 as cp2012 in dev mgr), just a blinking cursor and no activity on screen. Tera term local echo I turned on to see if I could type characters and I can, but hitting Enter does not go to the next line. Camera has power as it intermittently rotates without doing anything. shouldn't the light on cp2102 be green if it's communicating correctly to main board of camera? Soldered on J8 of foscam the rxd to txd of cp2102, txd of foscam to rxd on cp2102 and gnd to gnd. Power cord in computer is also plugged in so it's using that to make power to cp2102.

[@mecrayavcin]

Hi i need help :( i am new in this issue. I have only one question. İf i power router with its own adaptor, should i buy a 3.3 and 5 volt switchable serial converter? I want to buy this cheap www.robolinkmarket.com/cp2102-usb-uart-board.html This has no switcher. But if i dont connect VCC, i dont need 3 volt or 5 volt output? Am i right? You didnt connected VCC but you made a bridge and set that to 3.3. İs this possible that if i dont connect to VCC i mean netiher 3.3 nor 5 volt and only connect to rx,tx,grnd; the laptop usb volt i mean can it send 5 volt through rx,tx,or ground and can it fry my router? According to your answer i will buy voltage switchable serial converter. because those are more expensive. or that cheap one enough for me? Thanks very much

[@richardlloydusa]

You are welcome. I am not sure what you are referring to with "hello world" embedded firmware. I am not a programmer but I do use Linux firmware on this router called DD-WRT. Here is a video on that kzbin.info/www/bejne/sJivi3eFntKHd8U Thanks.

"Helo World" Means Build Firmware Image (ToolChain, Kernel,Libraries Included) That When Mounted On To The Routers NVRAM. Will Message the system is working correctly.

[@lauraskipper6040]

the type of cp2012 I got before seeing the video is WINGONEER USB 2.0 to TTL UART 6PIN CP2102 Module Serial Converter. www.amazon.com/gp/product/B01LRVQIFQ/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1. Is this similar to the Kedsum you used?

[@richardlloydusa]

Yes it looks almost identical to the Kedsum at Amazon: amzn.to/1u7Pmd8 but I can guarantee that it will work the same. BTW both are available at Amazon and cost the same why not just buy the one I link to and be sure? Thanks.

kumaresh raj Make sure you configure your serial connection as I show on the video at 9:05 once you verify those settings then more than likely you have your RX and TX lines hooked up to the wrong pins just reverse them and you should get an output. I did the same thing when I first connected the cables. Make sure you are connecting to TX and RX and if you don't get an output reverse the wires so that TX goes RX on the UART pins and RX goes to the TX pins. Please tell me if that fixed your issue. Thanks.

kumaresh raj Not sure if shorting those two will damage them. I have connected them incorrectly with out any damage
