K, I just followed the instructions in this thread. My xbox was banned. I bought a new EEPROM. I installed it via configmagic, unlock hdd, load new EEPROM from bin, set the DVD KIT thing to 1, which was the same as my old xbox EEPROM, region was the same. Updated it, locked the hdd and exited.. Seems ok, it let me on Xbox Live, asking me to sign up for a new subscription, which is fine.
Thing is, I loaded up Ninja Gaiden to test it, and all my save game files were corrupted and it said it couldn't load them. Is there anything I can do about this?
I don't know if this has spread to other games as well.
