Update #3: There are now PS3 Shop Reverters available HERE from tjhooker73.

Update #2: A guide is now available on How to Turn PS3 Demo / Kiosk Consoles Into Retail with JailBreak and also PS3MFW - Kiosk2Retail Without Downgrading for 3.55 and Below.

OK, for those of you who have a Demo PS3 these codes allow you to have full control of the PS3 features, and removes all limitations that the Demo Firmware (http://fshop01.ps3.update.playstatio...updatelist.txt) has.

To unlock your Demo PS3 go to the XMB, then Security Settings. While highlighted, press L1+R1+Select+Square and it will ask you for a 4-digit code.

Then enter the appropriate 4-digit code from below and your PS3 will now be unlocked!
