I need some suggestions for which direction to go in on this Xbox.
It started when I got this Xbox from a friend, who got it from a friend...egh.
Anyhow, it's a Xenon that had been JTAG'd, and the wiring had fallen apart. So, first thing I did was restore the wiring using the new Xecuter QSB, and dumped the NAND.
Then, I gave it a shot to boot, and is had error 0020.
So next I tested the GPU resistance via the caps, and it was at 0 Ohm. Bad GPU. So I got a newly removed GPU, with leaded balls.
I attached this GPU, and tried it. This time, it gave 0020. Went ahead and reflowed the GPU, CPU, ANA, and the top 4 RAM. Still 0022.
Soo, thinking this was a NAND issue, as it has been for me in the past, I have tried flashing with an XBR build, and a Xell built. Neither work. I don't have the Retail NAND, but I easliy read the XBR NAND that was flashed to it when I got it, so I believe I have a good KV and Config.
Any suggestions? I don't believe it to be a NAND issue anymore, just a strange hardware problem. ALSO, the NAND has a bad block at 0x02F1. I can not read, nor write to this block. Could this be the issue?

Anyone? 0020 to 0022 after new GPU, anyone?
EDIT: Also, the first post is suppose to indicate that I gave 0022 right after I attached the new GPU, as well as after I reflowed.
