How To Debrick Your NETGEAR WNR3500L Using A USB-TTL Cable on Windows

So you've gone and done it... you've bricked your WNR3500L.  Nothing sinks the spirits like constantly flashing lights and endless reboot loops.  However, don't lose hope or get frustrated - there's a solution to your woes, and it's called a serial console.

Before you think that this is too complicated for you, read on.  It's actually quite simple, but there are several steps involved that require completion exactly as stated.  Remember, you perform these steps at your own risk, but rest assured that I have followed these exact steps to great success and that you should be able to duplicate them.  The instructions that follow are for use on Windows systems.

[Purchase a NETGEAR WNR3500L]

Materials Needed

  • 1x Bricked WNR3500L 
  • Ethernet cable
  • Windows PC/Laptop
  • Installed TFTP client (Windows XP, 2000, and 7 have this built in.  Otherwise, see step 10 for installation instructions/links)
  • Teeny tiny screwdriver or similar implement
  • Electrical tape (Optional, but recommended)
  • USB-TTL Cable from FTDI.  You can purchase one of these from Mouser ElectronicsEnsure that you have model TTL-232R-3V3 specifically, or you can fry your router! See photo above.
  • Torx T6 or T7 screwdriver
  • Thin flathead screwdriver (Optional, but recommended)
  • NETGEAR Original Firmware for the WNR3500L (Download from here and put into your C: drive).
  • Patience.  Some of these steps may take multiple attempts.

Step 1: Crack Open the Router

Well, don't literally crack it, unless you want a broken router!  It's pretty easy to open, but be careful.  Use the Torx screwdriver to remove the two screws on the bottom of the unit first.

Now, you will have to unsnap the case from the router.  In the photo, look closely at the router's casing.  You may be able to see the tabs on the left and right side.  The panel you need to remove is the "top" panel - look at the back of the router and turn it so the text is right side up.  The top panel, when the router is situated this way, is the one you should need to remove.  Gently put your screwdriver (preferably flathead) in the seam and disconnect these tabs.  Once you are able to slide the case off, put the router aside for now. 

Note: The first time removing it, I needed the screwdriver to pry it loose, but on subsequent tries I discovered that the case "slides" and snaps into place.  Try various methods to find what works best for you.  You may not need an implement to unsnap the tabs at all, if you're lucky!

Step 2: Download PuTTY Program and Install

PuTTY is the nifty, free little program that you will use to program the router, also known as a serial console.  Download it from here, and install it using the self-installing executable.

Step 3: Download Cable Drivers and Install

Now, you'll need to download the drivers for your USB-TTL cable.  In a nutshell, this cable "converts" the USB interface of your PC to a serial output that the board of the WNR3500L can understand, so you can communicate directly with the board (i.e., not over your network.)

Download the proper driver for Windows from here and install it.  A reboot is not required, but recommended.

Step 4: Give your PC a Static IP Address

This step is to ensure that you will be able to communicate with 192.168.1.1, the default address of the bricked router.

Head to Control Panel => Your Internet Connection => TCP/IP => Properties and change your IP address as shown above.  Make sure it does not end in .1, .x1, or .xx1.

Step 5: Plug in Ethernet from Router to PC

Note: Do NOT connect the power to the router just yet.  

Connect the Ethernet cable you have in your possession to an orange port on the WNR3500L to the Ethernet port on your PC.  Note that it must be an orange port, NOT the yellow port... it won't work otherwise.  At least, it didn't for me.

[[page]]

Step 6: Modify the USB-TTL Cable for Use with WNR3500L

Take a look at the photo above.  See how each of the leads is covered by a small plastic tab?  Bust out your tiny screwdriver or whatever it is that you have that's tiny, and pry off the tabs on the black, yellow, and orange leads only.  If you choose to remove all six, you will need to wrap up the unused leads in electrical tape to avoid shorting anything out.  I just left the unused leads inside the plastic harness as shown above.  Once you pry the tabs off, the leads that you will use slip out easily. Now, you can plug the cable in.

Step 7: Find Out What COM Port Your Cable is Using

You installed the cable driver in step 3, right?  If so, head on over to Control Panel => System => Hardware => Device Manager, and click on the "Ports" item as shown in the photo above.  Note the "USB Serial Port" item with a designation of "COM3."  You'll use this information in the next steps. If you don't see that, plug in the cable and the Device Manager should refresh.

Step 8: Connect the USB-TTL Cable to the WNR3500L

Note: Make sure the router is still powered off and unplugged from power when you do this.  Don't touch anything metal either, don't want to take any risks of shock or shorting anything out, which is always a potential concern when tinkering with open electronics.

This part is particularly important, as if you don't connect these cables properly it will be very frustrating for you!   Take a close look at the photo above.  On the pinout on the board, you will see six pins.  Next to one pin it will read "JP1."  That is actually Pin 6.  Pin 1 is labeled with a "1" next to it.  Connect the cables as follows and as shown in the photo:

Black => Pin 6 (next to JP1)

Yellow => Pin 5

Orange => Pin 2

Note: In this photo, the black and yellow leads are seated properly.  I wanted to show you what an improper cable seating looked like; the orange cable is NOT seated properly.  Make sure all the cables are firmly seated to the pins and that they are not touching each other.

Step 9: Configure and Launch PuTTY

Hanging in there?  Do you feel like a geek yet?  It should feel good :)

Fire up PuTTY and you'll see the screen above.  Select the exact options as shown above; click on the Serial radio button, the port to COM3 (or whatever port was revealed in Step 7) and the speed to 115200.

Then, click on the very last item in the menu and choose the options above.  They must be exact: serial line of COM3, speed of 115200, Data bits of 8, Stop bits of 1, and "None" for both parity and flow control.  Once you are confident these settings are correct, click "Open," and you will see a blank window with a green cursor.  Nothing is supposed to be happening in there yet, so don't fret.

Step 9: Power on the WNR3500L and Press Ctrl-C

Now, you can finally connect power to the router.  Press in the power button and immediately press Ctrl-C on your PC, with the PuTTY window active.  This will bring you to what is called the CFE console; essentially, you're interacting directly with the board.  If this does not happen, double and triple check all of the previous steps.

Then, type in "tftpd" (without quotes) to bring up what is called the TFTP interface.  This will ready the router for programming.  If this step performed properly, you'll be left with the screen above.  Almost there...

Step 10: "Put" The Firmware Into Your WNR3500L In The DOS Prompt

Note: If you are on Windows 2000, XP, or 7, you have a TFTP client built in.  However, if you're on Win95, 98, Me, NT, or Vista - you do not.  

Instructions for installing TFTP on Windows Vista can be found here.

Here is one open source TFTP client for Windows that you can try.

Assuming that you have TFTP installed in some form, zoom on over to your DOS prompt. You copied the original NETGEAR fimware to your C: drive, correct?  Good.  Type "cd.." without quotes as shown above to get to your root directory, then type this command:

tftp -i 192.168.1.1 put FIRMWARE_FILE.chk

When you do this, the TFTP command will send the firmware file you indicated to the router, and you will get a confirmation as shown above.  If this doesn't work, make sure your router is connected to your PC properly, you have a static IP that doesn't end in 1, and that you can ping the router.

If this command is successful, your PuTTY console will start to get some action, and it will re-program the router.  Allow this process to finish, it will take several minutes, and wait until it is COMPLETELY finished or you will get a bad flash.  And nobody wants a bad flash!  You'll get a lot more text than is displayed above, but when it's done, you can try accessing your router's GUI via http://192.168.1.1. You will need to enter the "standard" username and password, consult your user manual for this information. (At the time of this writing, "admin" and "password" were used.)

Step 11: Rejoice and Relax... or troubleshoot

Hopefully, not the latter, but unfortunately things don't always go as planned.  If you're struggling with this procedure, have an unsolvable problem with your WNR3500L, or are on another OS let us know.  We're continuing to work on recovery guides for Linux and Mac OS X, so stay tuned!

Many thanks, but it isn't the "L" version - it is just the WNR3500 but the v2. I tried to install this version dd-wrt.v24-21061_NEWD-2_K2.6_mini-WNR3500v2.chk to my WNR3500v2 but it failed - I don't know why. I have got a spare but it would be nice to unbrick the WNR3500v2

Many thanks,

Hey guys, i am having trouble

Hey guys, i am having trouble with the process. I can get into the CFE command but when i tftp the firmware over, it says "programming..." then nothing happens. Ive retried this several times now. any thoughts?

*edit**
I have got the firmware installed and it loads fine the first time, for about 5 mins i can access the utilities but then, the console freezes and the access freezes.

this is what it looks like:

Hello,

I am trying to debrick this device, but I need to put jumper cables manually on the pin headers. Can you tell me what each pin does so I can select te correct ones?

What hardware do you use for

What hardware do you use for serial connection?
Do not close the circuit on router serial port with jumper. You can damage it.
Everything you need is a serial adapter (usb2ttl, arduino etc).
If you will use a PC serial port(db9), do not connect it directly to the router.
Remember that the voltage of the PC is usually 12V while the serial router uses 3.3V. If you connect, it's likely that will burn the router serial port.

[VCC] [RX] [ ] [ ] [TX] [GND]

http://wiki.openwrt.org/toh/netgear/wnr3500l#serial

Only needs TX, RX and GND.
You can use a multimeter to not confuse VCC and GND.
If RX and TX are inverse don't work.

Hello,

Hello,
I was running Kongs DD-Wrt Firmware and set the the Overclock to 1600 and out the router went. Both Power and Lan lights show Amber. I Have the TTL-USB serial cable and have tried to follow the guide from MyRouter/Forums to reload the firmware using TFTP and Putty on windows 8, But have had NO luck.
I have heard about reprogramming the CFE or changing the config of the Router. Can anyone help?

Given the fact that Netgear support is about as useful as a brick and has no repair facility of any kind, anywhere.   I suggest buying a Buffalo router which does a great job without the Genie crapware.   I don't like remote management as its become far too prying, limiting and restrictive on what you can and cannot do when it comes to configuration.  Has anyone ever figured out why some companies produce routers with strong output with wide ranging coverage but as time moves on to the end of warranty it becomes not so far ranging ?   One has to wonder does it have anything to do with marketing range extenders ?   Netgear is no longer on my list as there was never any need for Genie since upgrading firmware never required it in the first place.

the jumper terminal numbers

the jumper terminal numbers for the ttl connection are incorrect.   ground is the sixth,  the one opposite jp1. 

transmit is the fifth, and receive is the second terminal.    i had to hold down control-c keys before i turned the power on.

Hi guys! I'm stuck with my
Hi guys! I'm stuck with my R7000 and it turns out that when I'm in the CFE and I try to access TFTPD, he says:

CFE> tftpd
Invalid command: "tftpd"
Available commands: nvram, reboot, flash, batch, go, boot, load, save, ping, arp, ifconfig, show, help

*** command status = -1

and all this I do because it does not let me update medienate web because it tells me that the firmware file is invalid. I ran before: Xwrt Vortex.
