    I recently came across on article on how to JTAG xbox kernals that were not updated in the Summer of 09 update. I had a spare console in my closet for the last two years due to a bricked hitatchi drive. I have been unsuccessful of getting they key off the drive due to bricking it while attempting the two wire cross trick to put it into mode B.

    I thought this JTAG method may allow me to save the console by getting the DVD Key by dumping the NAND.

    So I've spent the last three nights trying to get this to work. I stripped down a printer cable and used a voltmeter to trace back the wires needed. I then stripped the cable, shortened it and added 5 100ohm 1/2 watt resistors to the listed wires and a switching diode. I soldered all the points and it went pretty easy.

    Hooking up the xbox to the PC with the LPT cable and then running Nandpro gave me the "Could not detect a flash controller!".
    So I read up on it and tried many things.

    Removed the 5 100 ohm resistors
    Resoldered the wires for the LPT cable
    Originally I had the J2D2.2 cable connected to the front panel by the reset button. I moved it to the back of the mother board.
    Moved the ground pin#16 to a different ground on the board
    Moved JTD2.1 to an alternate point on the back. (Subsequently I think I burned out the first point because of resoldering it twice)
    After doing these steps I kept trying again and kept getting the same "Could not detect a flash controller!" while running Nandpro.

    My questions are:

    Does it look like any of my solder points could be bad? Maybe bridging a point that I am not seeing? (see IMAGES)
    Is it possible to remove the LPT cable and test that just the JTAG hack is working so I can verify at least those points are good?I really appreciate any help on this.

    when you get no flash detected it means your wiring is wrong.re check your wires in your lpt cable before soldering.i find flux very helpfull when soldering.for the price of the parts i would just buy 25 pin printer port,kynar wire,and solder it myself.
    dont install the jtag wiring until you have sucessfully dumped your nand twice and compared it.are you using the afterdawn tutorial?its good i recommend it

    also try setting your LTP to one of the following in your BIOD

    EPP
    Bi-directional
    Both

    Make sure your wires are as short as poss, even if it means you have to put the xbox at the back of the PC.

    Heres his pics

    Thank you! My cables are pretty short and I have to put the xbox at the back of the PC. They are only about 7 to 8 inches right now. Really have to stretch to get it right.

    Thanks. I will try the resistors tonight. My LPT setting is on "BOTH" right now.

    My old (2001 model) lap top did my first JTAG on "EPP" setting.
