My cable also worked great.

Finally did a serial connection flash of stock firmware. Worked perfectly.

I have been testing speed with stock firmware, and always get a great 101 Mbps as expected.

I would be helpful to others if you posted how you recovered your WRT3200ACM.

These instructions where provided to me, so use at your own risk, but they work perfectly. It's designed for the WRT1900, but the steps for the wrt3200 are exactly the same. The pinout and location is the same, you only need to remove the front two screws to take the blue face off, no need to remove all 4 screws.

Be sure to check the entire article out for steps and software configuration information for Putty and TFTP. I was up and running in under 30 minutes.

ALSO TTL Cable pinout
Red - 5v
Black - Ground
Green - Tx
White - Rx

Agreed, thank you! Sorry, I was away for a while and didn't get anything posted. Your instructions are very detailed a much better job then I could have done. Very helpful!

Any other ways to do this? I am frustrated beyond belief and want to take this WRT3200ACM back, but can't without returning it to factor default. I've spent hours and hours on this this, with a laymen's technical knowledge and ability. My patience is gone. Sad

So, this won't work? It seem a lot simpler.

No it won't. You'll find how to do it in this thread. Either do it with a serial cable or wait till someone makes a revert file.
Next time don't flash any custom firmware unless you know how to get back to stock or unbrick your router.

I doubt it will work and you will end up using the USB to TTL serial console method anyway.

Use the method outlined in my previous post. If you run Windoze, you will need to find a TFTP server, and install the appropriate drivers and CoolTerm

If you only flashed DD-WRT once, you might be able to get back to factory by performing the 5 power cycles to switch boot partitions. (power off, power on, wait for power light to come on, immediately turn off, repeat 5 times) If you happen to be successful booting to factory, then simply re-flash the factory image to overwrite DD-WRT boot partition.

So just a heads up I forgot to mention, my Adafruit cable is of course 2.54mm (I forgot about the pitch difference) so I had to get a 2.54 to 2.0mm adapter in case any of you need one:

https://www.amazon.com/gp/product/B00HFZK652/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

And do the opposite of what I did in the photo (it's towards the heatsink not on pin one, for some reason I did it backwards Rolling Eyes )

Interesting, I bought the same cable as you, but didn't purchase the adapter and it still worked for me.

They could have changed the cable since I ordered it last year but, yeah I tried it without the adapter and they would just fall off, and I didn't want to chance it.
With the adapter it fits snug and won't come off easy, and the cable I have plugs nice and firmly into the adapter...

Just hit the same problem - no way to revert the 3200acm to stock. Any word from Kong on adapting the previous one to work with the 3200?
