January 19, 2012 // 11:30 pm - 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)

Installation instructions:

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)

  • downgrade to 3.55 using the downgrade tools from e3 (Of course when downgrading to 3.55 make sure you use a different hdd than the hdd which you were using 4.00)
  • once booted back into the xmb turn off the console
  • swap hard drives turn on the system, press the PS button and you will be asked to reinstall the firmware
  • place the pup file from the e3 downgrade tools in the normal PS3/UPDATE usb folder and follow the on-screen instructions to reinstall the firmware
  • then install dev_blind.pkg & Blackb0x FTP from install packages
  • run dev_blind then BlackB0x and FTP into the console
  • goto /dev_blind delete everything and replace them with the customised dev_flash
  • press the ps button and the console should reboot and and ask to reinstall the firmware again, switch off the console and swap the hard drive back
  • turn on the console press the ps button twice
  • the console should boot back into 3.55 Rogero
  • goto system update and install 4.00 OFW
  • once installed turn the console off again and swap hard drives back and you should boot into a modified 4.00 retail firmware.

My package (downloadable at http://www.multiupload.com/20LFVKUHDG) includes:

  • My modded dev_flash
  • OFW 4.00 PS3UPDAT.PUP




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).

If I understand corectly this, he mean that on a PS3 in CFW 3.41/3.55 & using a hombrew which allow-us to mount a dev_flash fw image, we could load the dev_flash 4.00 = the firmware 4.00 without installing-it !! just from a USB drive !! a virtual machine !!

Like using this Jaicrab USB Firmware loader: jaicrab.blogspot.com/2010/09/ps3-usb-firm-loader_22.html

But is this really possible, was it done before !!! launching OFW 4.00 without installing-it !! it seems to be so hard in my mind, am I wrong ?
