So I wanted to update my dashboard on my xenon jtag, so i got the new freeboot and wrote it to my nand using flash360. After everything was done, i powered down my xbox, power cycled and started it back up. Once i turned it on, the screen stayed black and nothing else seems to happen after that. The power light is on on the rf board and that's about it. (Also i can not boot into xell) So I did some research and I bought a Nand-X kit from a site. So what I am concerned about is what I must do when I get this and how i can restore the nand and put the freeboot back on. Thanks in advance.
