A lot of people are coming here to grab the Kinect dashboard updates that are being uploaded, but there's a new protection in it. I can't see a thread about it, so apologies if it's been talked about already.

New Xbox360 Disc Protections? Bans to follow? « xorloser’s blog
This protection is why many people haven't been able to boot Fable 3, as it's the first game that has the protection on the disc. Here's what happens when you boot it on a console with the Kinect dashboard: -
1. The game is recognised by the 360, will install, but if you try and boot it, it says "This disc is unreadable".
2. Your console is then flagged for a ban for failing the AP25 challenge. You can check if your console has been flagged by using XVal 2.0: -

3. Your gamertag will then only work on that particular Xbox 360. If you move it to another 360, it will show up as corrupt. A lot of people use an offline, flashed 360 to play games, then they sign into Live on another 360 to update their achievements/gamerscore. This stops you doing that.
The above 3 things happen just by booting Fable 3 on the Kinect dashboard. You don't need to connect to Live in order to suffer these effects, so it doesn't matter if you stay offline. I should clarify that only backups of Fable 3 are affected, not originals.
New firmware is being worked on, but there's no ETA. The first Wave 7 game has appeared (Hasbro Family Game Night 3), so this may contain the Kinect dashboard update - I can't confirm this though. It's not known which, if any, other games apart from Fable 3 contain the new protection. It's possible that the protection can be added to older titles via updates rolled out on Xbox Live.
