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:
This installation procedure is the similar to technodon's original dev_flash hdd swap procedure
For this you will need two hard drives a e3 flasher or similar device to downgrade your PS3 (assuming that you're on firmware 4.00 and you have an e3 flasher)
My package (downloadable at http://www.multiupload.com/20LFVKUHDG) includes:
Sorry about the camera quality, it's the best I can manage.
P.S. BTW the "nas_plugin.sprx" in this dev_flash has not been altered to achieve "Install Package Files". Also for those who will analyze my modded dev_flash, you will find that I have used debug .sprx files from the a debug 4.00 pup.
P.P.S. I originally intended to get "★ Debug Settings" to work with this. But usage of "debug settings" required the ps3 to use a debug vsh.self, and that crashes the ps3 when trying to load applications (I did some other things as well to prevent the PS3 from giving me a RSOD when I swapped the vsh.self files, I'm not detailing it in public because I don't want Sony to patch it).
