it shouldn't be too hard to put it on the router board, even if you have to solder it. but the whole jtag process... i'm not sure.

check the tftp method before. i managed to unbrick a router by doing that.

The seller says that his provides a super easy De-bricking Repair guide.

What do you think?

I have his kit. It is easy for me, but I'm quite used to fiddling with embedded systems and firmware, and soldering. As in, that's a big part of what I do for a living.

Can you tell me the software that is used with this package?

Did it work for you?

Will this work in the case that i flashed the router with the WRONG firmware. As the tjtag method only seems to do a nvram reset and not a firmware .bin reflash.

The JTAG can be used to debrick anything that got messed up, EXCEPT if the processor has been overclocked incorrectly --> recovering from that is trickier, because the clock speed is set very very early during initialization. It is possible though, by shorting pins on the flash chip temporarily.

I think I used tjtag3-0-1 under Linux. The MS-Windows version didn't work as well when I tried it. This was all 2 years ago.
