I've read a lot of posts and I still can't get this xbox jtagged. I have jtagged at least 6 xenon boards and they all work perfectly. Now on the non xenon boards I get the nand dumped every time and loaded every time with no errors. But when I boot up the xbox after I get 3 rings. I currently have 4 non-xenon boxes doing the exact same thing. I've checked my solder joints over and over again with my fluke meter. I've also tried to non-xenon jtag kit and I get the same outcome. Just to let you know I'm not a newbie at soldering. I'm an electronic technologist.
