January 20, 2012 // 12:30 am - 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).

Joey inspired me to make a new kiosk firmware however this one will only install on 3.55 make sure you have a hardware flasher before installing this as there is no other way to downgrade. Features include:

1. Added Custom Coldboot
2. Patched to allow installation of Sony Retail Signed Packages
3. Added install package file options to the Game Category

i tried to remove XMB restrictions to playstation home and the store, it might not be possible now. i think sony changed something? maybe ps3hen can take a look.

What are you talking about? Apps made for CFW won't work on OFW, because they utilise peek/poke.

one thing it does actually prove is that sony did add more verification checks to check the integrity of the pups. any changes made to dev_flash files including cold boots gives data corruption errors. so there will not be any new custom firmwares installable on 4.11 you will need to downgrade back to 3.55 and update.

install package files doesn't even work. by work i mean not even sony retail psn signed packages. maybe some kind of special shop packages install ?

All 3.55 apps should work as how do you think lower firmware games and apps still work.

All we need to do is maybe sign them a different way as its probably blocked the signature for homebrew.

Just sign homebrew for a lower firmware should still work in higher firmwares.

This is not good, i'm sorry but like Kakaroto told me 'your just telling sony how to patch their firmware without any good reason'

when there finally is a jailbreak we wont have install package options

i'm going to install this just cause he says that you can convert the console back to retail which i wouldn't have thought is possible like he said also i very much doubt that you can install this on 4.11 cause if the new security checks and remember if you update from 3.55 you have no way to downgrade without a nor or nand flasher!

its very good actually. i'm quite surprised how he managed to convert from retail to shop then back to retail on 4.11. going to test it on my unhackable 3000x series console.. wish me luck!

it even works on a unbackable 3000x series console sony will be breaking down your door and taking your ps3's MR. Joey Johnson, shame that homebrew is never going to run on this unless he is a specialist in algebra equations. but well done for hacking sony's latest model!

So this is a kiosk firmware update with retail firmware flags. And the "return FW" is a retail firmware update with kiosk flags. This will only be able to install retail pkgs so that's probably why "no packages install", as all homebrew pkgs are not proper retail pkgs. Nice POC, but I don't think kiosk fw will lead into an exploit.
