For those curious, this PS3 CFW / MFW is a modified 4.10 Kiosk / Shop Firmware via PS3MFW Builder intended for installation on PS3 3.55 Retail consoles.
1. Custom Coldboot
2. Kiosk/Shop XMB restrictions have been removed so PlayStation Home/PlayStation Store work fine.
3. Modified to allow installation of retail signed packages
http://www.ps3news.com/forums/images/smilies/icon4.png Notes: DO NOT install this unless you have an E3 flasher or Progskeet type device to downgrade your PS3 to 3.55. Unfortunately 3.55 signed PS3 homebrew does not install/run. Also be aware it doesn't load any PlayStation 3 game backups so you will need to have the game disc to play them.
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 2464.
PS: PS3Hen if you would like to add XMB Manager that would be great http://www.ps3news.com/forums/images/smilies/icon12.png
