Revocation is done through the use of Console Revocation Lists (CRLs). If your console's ID is present in the revocation list, then your console has been revoked. There are two types of CRLs, static and dynamic.
A static list refers to a list that is saved onto the flash inside your Xbox360. This list is updated when system updates are performed on your console. The Fall'08 update contains an encrypted version of this list in the file "$SystemUpdate\su20076000_00000000\data.bin". When the list is installed onto your console another layer of encryption is added using your Xbox360's unique fusekey and the result is saved to a crl.bin file on the internal flash.
A dynamic list refers to a list that is sent to your console when you connect to Xbox Live. This way an updated revocation list can be employed without requiring a system update.

Recently Microsoft has been adding all of the flagged consoles to the list. To recover you must overwrite or erase the crl.bin on the internal flash.. which would be possible if we were able to force install an older dash which included an older crl.bin or through jtag (but this is limited to systems without the recent update anyway and certain versions of hardware).
I thought I'd remind everyone of this so we can focus better at a solution.
A solution to eventually get back online would require a new console id or a way to spoof a different one. To see your real console id visit

So... who can overwrite or alter the crl.bin first??
To verify all this, our console ID's will most likely be in the updated static list coming in the next big update this month (someone with jtag could dump it for us once their console is updated).. and to answer some people's questions, if your system has been flagged but not banned yet, a future game will probably incorporate the updated crl.bin and ban your system once you play it.
This seemed important enough to deserve its own topic.
