A member named legueux from gx-mod.com forums has recently released detailed information and now a video to show how he has managed to unban his Xbox 360 Console on Xbox LIVE.
It's not like everyone is going to be able unban their consoles just yet because you need the Xbox 360 CPU key (which can be found using the Hypervisor Exploit or Timing Attack to downgrade first). Many additional tools are also be needed to read the XBOX 360 NAND before you can flash the console with the new information and unban it.
Here are the full list of steps took to unban a Xbox 360 on Xbox LIVE:
Downgrade banned 5787 PAL to 4532 NTSC U, updated again to 5787 via HD. Still banned.
Downgrade banned 5787 PAL to 1888 PAL, updated again to 5787 via HD. Still banned.
Patched original 1888 PAL dump with the last number of the Xbox 360 serial in the keyvault (location A0 to AB) changed. Still banned.
Patched original 1888 PAL dump with the all the numbers of the Xbox 360 serial in the keyvault changed. Still banned.
Replaced the full keyvault in his original 1888 PAL dump of the banned console with a keyvault of an unbanned console. Connected to LIVE OK, updated to latest kernel online OK, still connects fine to LIVE.
The video linked below shows a banned console and how it'll has been unban and will re-connect to xbox LIVE again after he has flashed the console with the 1888 dump with patched keyvault of an unbanned console.
