It doesn't seem anyone has a real idea about this. I have asked and all you get is people guessing. I have a copy of the original EEPRom taken before I accessed the XBOX LIVE TAB (without any form of connection to the net) so I figured if I flash this back then unless they flagged something on the hard disk there would be no trace that I had accessed the livetab.
IF they are flagging on the xbox than surly all these people who switc h EEP romswould just be banned the next time they log on as the flag would remain set on the hard disk. I can only see that MS is flagging something on the EEP Rom itself or you could not unban your xbox without formatting the drives and I not heard anyone doing that before they switch EEP roms to an unbanned one.
So my advice would be if you have a backup of your previous EEP rom then to flash that back. Has anyone compaired an old rom to one that might have been 'flagged' to see if anything has changed?
Is anyone even certain MS is going to such steps to ban xboxs that they would do it BEFORE YOU EVEN BUY A LIVE KIT?? I mean seriously..banning an xbox before you even have the kit seems VERY odd way to go about it. I could remove my matrix, burn it, install live and according to the theory, STILL be banned... That seems odd to me!?
Any proof of this??
