70w ago - Here is my first PS3 4.10 CFW (Custom Firmware) / MFW (Modified Firmware) which includes the Install Package Files option in the PlayStation 3 XMB for those interested.
Download:
PS3 4.10 CFW / MFW with Install Package Files by TechnoDon (

Warning: Read
Notes below before installing!)
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.
Changes:
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
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.
Enjoy!
PS:
PS3Hen if you would like to add XMB Manager that would be great
