Yes i did try openocd and really no luck, im not sure whats really going on as most tools I have tried does not recognize the hardware, all the searching and research i have done leads me to tjtag as having the wrt160n cpu and flash ram specs written in but when I asked Tornado about a version of tjtag that works with tumpa he suggested I write here about having support put in zjtag explaining it should not be hard to do, so for now I have been trying different tool sets and jtag work arounds with no luck, either the hardware specs are not present or something doesn't work with the os meaning both windows and linux 64bit, recently I purchased a pci parallel port card, also 2 different styles of parallel jtag cables from TIAO with no luck so far from either of those as well, but on a positive side I have used some of your advice and tips I found in other post for other individuals as well, you have been a huge help thus far without realizing it ...
-----------------
Long story short version, this router I am working on is one of my routers that was damaged at a relatives home when a storm caused a tree to fall on the house damaging one side of the home and clipping the electrical lines causing a brown out type scenario.
When I retrieved the router and tried plugging it in, all the lights blinked in unison, after some research I found out that the blinking was a sign that the power adapter was not producing sufficient power to the unit, I ordered a replacement power supply which solved the all lights blinking issue, now the router would power on with just the power light flashing, but there was no web interface, no assigning ip addresses , I tried tftp with success to the router but still no change, no web interface, no assigning ip addresses and power led still flashing (I am not listing that I did follow all steps 303030 hard reset and so forth to cut down on the amount of typing here).
I ordered a PL2303 USB To RS232 TTL Converter Adapter Module which I attached to the routers serial port from which I was able to see the routers boot sequence and that the router was boot looping over and over, from there I was also able to put the router into tftp mode and watch it as it loaded the firmware and give a success message about installation, but still after waiting and 30/30/30 hard reset, no change it would still boot loop continuously, no web interface, nothing, well after a long day of working with it, I made the mistake of using telnet to try and send firmware to the unit, worst mistake, hard lesson learned as I believe this corrupted the cfe as now it does nothing via telnet there is no booting and the power light stopped blinking, the wireless light is lit very dim, the wps light is lit.
Now comes the jtag fun of it all ;D , allot of the information I found on de-bricking this particular router I found on the dd-wrt forums, this is when I first purchased the tumpa adapter not realizing at the time tjtag didn't support it, dd-wrt forum is where I learned tjtag had wrt160n support added to it, now buying the tumpa adapter is when I learned of zjtag, the tumpa adapter and zjtag work great together and got me closer to maybe bringing change to this router but even with some options like skip detect ect there still is the problem of not having the proper flash ram information to properly try and flash back cfe to the router, as i said previously I recently bought a pci parallel port adapter card and purchased jtag parallel debricking cable (buffered) and a Universal JTAG Ver 2 parallel adapter, then comes the other problems, through this parallel adapter for which tjtag is supposed to work, on Windows 64 tjtag64 will not or does not contain all the command sets such as change the port address on to which the parallel port is located, tjtag32 does this port location change but however it wont load the giveio.sys driver file on a 64bit os Windows 7,..... linux64, Mint distro to be exact on the other hand I cant seem to find or figure out the parallel port address of the card, maybe another distro would be better informative, but anyways I am going to try openocd again with the parallel cables through windows and see if anything becomes possible, although i do believe there is just no hardware support for this router in it, also try the tumpa adapter again with zjtag, I feel as though I am running out of options here, for all I know the router may not even be salvageable given as how tftp didn't stick when it was first stuck in its boot loop cycle ??? ..
