Ok, I also have an early Xbox (V1.1) and am getting the "Xbox Live Not Found" error. I'm getting the same XYZ code as many:
X: 0000 - F001
Y: 00C2 - 03E0
Z: 0000 - 0000
Here's the situation...
Xbox Live has been working without issue on my modded xbox for a few months. I connect and disconnect the ethernet cable everytime I use XBLive. I recently upgraded my 160GB hard drive to a 250GB. I used a Slayers v2.5 setup disc to format/install the stuff on the new drive.
As soon as this happened, XBL wasn't happy.
I still have my original drive, but haven't tried pulling anything from it. Which files should I grab? All of C? Some of C?
Also, in Config Magic Final, my video settings are as follows:
Video & XBE Region : NTSC, Region 1
DVD Kit Zone : 0
Are these mismatched? I tried "on the fly" editing the zone to 1 (like on my other modded xbox) but no good.
Final bit of info: I have my other modded xbox plugged into the SAME router, used the SAME Slayers disc to set up my drive, and it can connect to XBL no problem. This is the only thing I have that supports the idea that a "00C2" code could mean the EEPROM is banned. I'm going to check it by using my working xbox's EEPROM on the bad one.
