I followed the reference and bought an Arduino Uno which is available here in our country, because I have a previous issue with the shipment of the Universal JTAG from DIYGADGET as there is an issue shipping in our country.
I tried my luck, using the ported tjtag for Arduino and loaded the Arduino with the arduiggler.pde sketch. And also that the tjtag arduino is hardcoded to COM port 4, as I do not have an editor to edit the source code of tjtag arduino.
1) I was about to upgrade the dd-wrt of my Asus RT-N16 when it suddenly did no longer boot-up
2) It has been more than a year since my Asus RT-N16 no longer works, only the light for the power is lit at all times when I tried to power it on
3) Already tried 30/30/30, push the WPS to activate the recovery mode, ping the Asus RT-N16, access the Asus RT-N16 via browser to back-up cfe, TFTP... and nothing works
4) TUMPA or Universal JTAG adapter from DIYGADGET, no but no thanks... they already told me that they have issues on shipping in our country, but they did refunded my purchase in that case...
5) I recently bought an Arduino Uno because I found a thread/topic indicating that Arduino works and a TJTAG port for Arduino is made available (in EXE for Windows)
6) My problem now is it reads the CPU of the Asus RT-N16 through the Arduino Uno but it does not recognize the Flash Chip, so there is no way to recover the cfe nor flash a dd-wrt firmware on my Asus RT-N16
7) Hopefully someone can help me to fix my Asus RT-N16 so we could also share the information to others that also needs a fix like this
8) If the TJTAG for Arduino needs updating, we could share it here, also an EXE for Windows port of the TJTAG for Arduino is a plus...
Well, as per my story:
1) I can no longer access the GUI of my Asus RT-N16
2) I have followed the procedures in recovering my Asus RT-N16 over a year ago from the wiki even before posting my recovery using Arduino Uno
3) I already tried the 30/30/30 reset procedures over a year ago and nothing works
4) I already tried pressing the red WPS button and it did not load the recovery page
5) My Asus RT-N16 is no longer pingable, even if I ping using any IP address I known for my Asus RT-N16
6) The backup cfe page is no longer working, as I can no longer ping my Asus RT-N16 and its IP address is no longer known
The thing that I could ask is how can I proceed with the recovery of my Asus RT-N16 despite its non-detection of the Flash Chip.
With the USB-TTL UART adapter, there is no available USB-TTL UART adapter locally here in our country and shipping from other countries is blocked due to COVID-19 pandemic, prioritized shipments are medical supplies and essentials, also it will take a few months, if ordering is possible, and I have a very limited money to buy items online.
Using serial instructions by using Putty does not output anything, its all blank, I followed the baud rate and other required settings for Putty session, including the COM port 4 because tjtag is hard coded in using COM port 4.
I already tried 30-30-30 several times but it does not work. Also the Asus firmware restoration tool does not work as my Asus RT-N16 is not pingable at all.
The solved Asus RT-N16 topic/thread provided pertains to using Raspberry Pi whereas I only have an Arduino, because the Raspberry Pi is too expensive here in our country as expensive as the Universal JTAG or TUMPA of DIYGADGET including shipping fee.
Is there any updated JTAG software that supports the Asus RT-N16? Because the TJTAG of Tornado is no longer updated and it seems that Tornado is no longer active. Hopefully someone can come up with a better and updated JTAG software and also the JTAG software supports the Arduino as a JTAG cable/wiggler.
I only need an updated JTAG software to solve my problem in my Asus RT-N16.
Based on the Asus RT-N16 wiki the jtag port did not require 3.3v nor 5v. And as you can see on the output of the TJTAG JTMOD on my first and second post the Arduino Uno has read my Asus RT-N16's CPU Chip. I used the included jtag sketch for arduino, also followed the wiring guide on wiki and JTMOD.

Hopefully someone will give you the information you require. I tried to give you a viable option of doing a serial recovery (which is a different header on the board altogether). _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

Well, sad to say I have not backed-up the cfe of my Asus RT-N16 because I just recently bought an Arduino Uno board for the recovery purposes. But I will look in to your experience.

Hi wosk, I have read your experience, however you have used a wiggler cable probably an LPT (parallel port) which currently I no longer have a desktop computer that has an LPT port. I now currently have an Arduino Uno which is easily available here in our country and your attached downloads is no longer available to be downloaded.
Hope an updated TJTAG for Arduino will be released and supports my Asus RT-N16.
I have some things that I can think of are:
1) Can I recompile jtrimble's TJTAG JTMOD for Arduino that includes the chip code of the Asus RT-N16 flash chip? So that the TJTAG JTMOD for Arduino can recognize my Asus RT-N16
2) Do anyone has any idea if there are other JTAG softwares that supports Arduino and supports the Asus RT-N16?

Using serial instructions by using Putty - tell me please, where to find this instruction?
