Ok I think I better CALM DOWN...I am about to go crazy!!! Ok I got banned from live, so I got a friends xbox thats modded and that doesint want to go on live. Then I got ConfigMagic from xbins and used it to unlock his HDD and then used it take his eeprom it gave me 6 files: EEPROMBackupBeforeLock.bin, EEPROMBackupBeforeLock.cfg, EEPROMBackupBeforeLock.txt, EEPROMBACKUP.txt and EEPROMBACKUP.bin. Logicly what I was looking for was EEPROMBACKUP.bin, so I took it, renamed it to eeprom.bin and put on c/. Then I launched eepomagic and made a backup of my banned EEPROM and replaced it with the unbaned one on c/. Then i turned off my xbox and now I CANT USE MY XBOX ANYMORE!!!MY XBOX SHOW ANYTHING ANYMORE! JUST A BLACK SCREEN AND THE RED LIGHT IS FLASHING! SOMEONE HELP PLEASE!

Oh yes and I unloacked my HDD before putting the eeprom.bin folder on c/.

Always try to follow tutorials when doing such important things, as I have a tutorial that explains how to use Configmagic properly.

Sounds like you have a bad EEPROM flash.. check out this thread:
