xbox live

First, please tell me you have the X2 4980 or 4981 bios.
If so, then the reason you could not connect was because the bios stopped you from connecting.

If you don't, your banned for good. Each xbox has it's own signature (eeprom key). MS bans it, meaning you xbox is banned. Your account is however NOT banned. Anyways, you have to obtain another eeprom key from an xbox you know will not go online. Basically, your switching xbox identities. If MS detects another xbox using the same key constantly at the same time, it will be banned again.

And you can never use backups online, no matter what.
