Hey I was wondering are all the Xbox 360's with the 8955 Dash downgradable? Also will you guys be selling a Downgrade Kit?
I am really interested, I am currently going to school for IT Programmer/Analayst so i know my way around things.

I guess it is only downgradable if you format your hard drive and place this update instead - http://digiex.net/downloads/download-center-2-0/xbox-360-content/dashboard-updates/1780-nxe-full-dashboard-avatars-offline-install-june-2009-a.html Or you can also use Xplorer 360 and delete the $SystemUpdate files. I think a blank hard drive would do.
If worse comes to worse, you might have to hack into the NAND of the Xbox using a JTAG kit somehow. I bet the dashboard update is stored in there since you don't have to plug in a storage device for the latest dashboard to show up. Initial Setup doesn't help.
By the way, the latest 9199 update allows banned hard drives to use the install feature. You might still need to downgrade it for you to JTAG your Xbox.

Holy crap, don't give any false hope! That dashboard update has already blown efuses in the CPU which makes all previous dashboards unbootable, so even if you use a jtag connection to force flash an old firmware it won't boot.
