70w ago - Below is a video demonstrating my PS3 4.00 Dev_Flash modification, which simply allows users to install Retail signed package (PKG) files from the PlayStation 3 XMB.
Note: This modification does not allow the installation / usage of unsigned content / PS3 homebrew etc. This is purely a convenience hack and is aimed for use by those who have hardware flashers which allow dual boot.
After technodon's work creating a modified kiosk dev_flash which lets you install retail signed package files. The restrictions of having to use kiosk firmware inspired me to find a way to add "Install Package Files" for retail firmware.
This is hack does the following things:
adds "★ Install Package Files" and "★ /app_home/PS3_GAME/" to "GAME" on the XMB (allowing the user to install retail package files anytime they want)
adds other debug functions which are small but still there
does not give access to "★ Debug Setting" (reasons for this are explained below)
This installation procedure is the similar to technodon's original dev_flash hdd swap procedure
