Recent estimates have said over 1 million gamers have been affected by Microsoft's 360 bans. Modders have attempted to free users from Microsoft's grip by releasing what is known to us as "iXtreme LT". According to a forum post on Xbox-Scene you can now unban your Xbox 360.
------------------------------------------------------------------
"what you need:
your 8955 live console + cpu key
a 2nd unbanned console
nandpro b + flash cable
xell loader
degraded
1888 fs
robinsod's flashtool
process:
use nandpro and dump nand from unbanned console.
flash xell and use jtag hack to obtain cpu key.
use flashtool to extract file system.
dump nand from 8955 console.
use flashtool to patch nand dump with kv.bin from unbanned console.
save patched file (patched_kv.bin).
open degraded + 1888 fs.
create 1888 downgrader image (downgrader.bin) from your patched_kv.bin file.
flash downgrader.bin to 8955 console.
attach hdd + ethernet cable and boot console.
connect to live and update to 8955 dashboard.
console is now fully working and unbanned!"

This is a highly complex process which relies on a number of free tools and in doing this you may be breaking more laws than you already have. YourEMGN does not recommend this process in any form.
