I bricked my wrt54g v2.2 really bad, ground to pin 16 and shortening pins 15-16(right?) didn't work anymore. So I made myself a nice little jtag cable. Put 4 100 ohm resistors on the board and a paralell cable on that. The router was able to go into failsafe, but after i tried to flash it with WRTJTAG.exe (the one that comes with a IO.dll) the memomy circuit seems to have died : /
The first time it seemed that everything was going ok and it worked for a long time, writing the new firmware, it finished and died.
The prog now complains about not finding the flash circuit, but reports that it finds the chip. Should I just buy myself a new wrt/asus or try something else (I'm a broke electronics student so all suggestions are welcome)?
The cable works properly and is set up this way (Xilinx Type III compatible JTAG cable)
DB25 pin 2 -------> 100ohm resistor -------> JTAG header pin 3
DB25 pin 3 -------> 100ohm resistor -------> JTAG header pin 9
DB25 pin 4 -------> 100ohm resistor -------> JTAG header pin 7
DB25 pin 13 -------> 100ohm resistor -------> JTAG header pin 5
DB25 pin 20 --------------------------------> JTAG header pin 2
DB25 pin 25 --------------------------------> JTAG header pin 2

Also the weather outside is horrible! It's been raining for a week now, really cold rain(I live in Norway). If someone could fix this it would make me very happy.
thnx
