from a post on 360mods.net I THINK I HAVE AN IDEA!!! Whether it will work or not is a different matter...
If you DE-SOLDER the EEPROM chip on your 360 motherboard your console should still work fine and should work online too. The Eeprom chip itself stores the Dash and other "Upgradeable" pieces of 360 Software so if we de-solder that it could possibly stop the update from working and therefore being banned?
Sectors
1 copyright notice, zeros, unencrypted numbers
2 encrypted data
@2MB filesystem, unencrypted, but content encrypted, config not
These sectors could be the numbers that appear when you are banned the error numbers, so by removing this chip it could POSSIBLY send the numbers back to their original status and therefore stopping you being banned from LIVE.
If someone could try this out on a banned console and see if it works it would be much appreciated!!!
Heres a link to what the eeprom chip looks like and more info:
