How did M$ actually block the disk? Are they checking the signature of the default.xex to see if it is the Kiosk disk? How does the 360 after the update only block this particular default.xex on the Kiosk disc and not any other default.xex on a retail game?
I haven't seen the code so I don't know exactly how they did it. You do imply that you don't understand how they could block these xex's and not all others. I can offer one solution to the problem just to show you how simple it would be. Since these xex's can't be changed due to invalidating the signatures it's quite simple to just do a hash check. Look at the checksum and then explicitly deny any xex with this checksum from running. Go through the whole kiosk disk and deny all hashes of the xex's on the disk and you have effectively blocked the kiosk disk while allowing all others. Again, I don't know how they did it but there is more than one way to skin a cat and this is just one very simple solution.

what i personally think they check for now is the little video that you get when you put your xbox 360 game in a normal DVD drive. when we burn the kiosk disc, we just burnt the files, not that video. it'd be relatively easy for MS to check for that video, and since all demos and games have to have that video, a check like that would mean you could weed out the backups from reals. obviously when we can boot byte to byte backups this protection will be useless, but until then its another obstacle they've set out for us. i don't think this check was to prevent the kiosk disc necessarily, but the backups we've managed to rip.

I've heard a rumor that the original Experience 360 Kiosk DVD was a true XBOXDVD, complete with video track. But Team PI noticed that the XEXs were also media flagged to run from CD/DVD-R, so they ripped the disk just like a X360 game, extracted the files, and made up the DVD-R ISO.
Very doubtful, but this may also be the case with the replacement demo disk.
So a question is, does an original of the first Experience 360 Kiosk DVD still boot after this update?

is it possible to remove the new dash update?
On the X360 the Dashboard is stored in Flash memory - and I don't believe any way to access/rollback this has been released.
Interestingly, a log text file that was left on the Kiosk DVD appeared to be a directory listing of the Flash memory, following an upgrade, and its contents seemed to indicate that the previous Dashboard was backed up, not erased! There'd be no point backing it up if it's never retrievable!

There would be a point if there WAS some major fault that M$ didnt notice before they released a dash. i bet they know how to roll-back dash versions

Indeed
. Try holding in the unit's power button for 5 seconds during power up.

well if you socketed the flash ship you could possibly "hotswap" flash chips immediately before doing an update, so you'd have one flash with the old dash, and one with the new

It already did. Some kid sent his xbox in and it came back with one in the drive.

so for those of us with the updated dash. Are we screwed? anyway to reset the update and go back to the previous version?
Not right now, you can't.

where is the dashboard update being saved? on the Hard Drive? Just wondering if swapping the harddrive with a new one would reset the update.
Its actually in the controller! All we have to do is swap them.
No, but for real, its on a flash memory chip on the motherboard.

Would anyone know if DVD RAM Disc work in the 360 dvd rom drive
the old xbox will work (backups)with them if you hookup a newer
lg drive or burner (gdr8164b)(4167b) you may be able to change
the write bits on the dvd ram disc to send the right M$ header signeture.

Ok, I got a hold of the original pressed kiosk disc. It still boots. So they must not be blocking that paticular disc titleID. My guess is there is some sort of patch included so that that titleID will only boot from retail and not dvd5 regardless of the mediaflag.
Well, that's great. Can you rip the dvd and the ss, and put it up to some site? Maybe we can continue with the swf replacement...
