once installed turn the console off again and swap hard drives back and you should boot into a modified 4.00 kiosk firmware.
NOTE: This only allows installation of retail signed packages and is not modified to run unsigned code..
To Unlock the XMB: Hold L1+R1+Select+Square simultaneously. When the security settings icon is selected. It will ask for you to input a code (four digit code). Enter 0000 if that doesn't work try 0219. With a video here:
Quick note: If you want to play games online you need to download and install the update via install package files cause kiosk doesn't download game updates. I just use charles to hijack the links and download them from a second PS3. Or you could boot the game and download them on 3.55 before you copy dev_flash and update to 4.00
Can install retail packages on 4.00 KIOSK firmware, can't mod to run unsigned code yet.. maybe you can?

Joey inspired me to make a new kiosk firmware however this one will only install on 3.55 make sure you have a hardware flasher before installing this as there is no other way to downgrade. Features include:
1. Added Custom Coldboot
2. Patched to allow installation of Sony Retail Signed Packages
3. Added install package file options to the Game Category
i tried to remove XMB restrictions to playstation home and the store, it might not be possible now. i think sony changed something? maybe ps3hen can take a look.
