140w ago - Shortly after the PS3 Firmware 4.00 Dev_Flash dump by UpSilon I have posted my [Register or Login to view links] and video (below) for PS3 Demo / Kiosk console owners.

WARNING: Modifying dev_flash can be very dangerous! USE AT YOUR OWN RISK!!!

For this you will need two hard drives a e3 flasher or similar device to downgrade your PS3 (assuming that your on firmware 4.00 and you have an e3 flasher)

  • downgrade to 3.55 using the downgrade tools from e3
  • 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 files included in the download when finished copying
  • 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 kiosk firmware.

NOTE: This only allows installation of retail signed packages and is not modified to run unsigned code..

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 0000 if that doesn't work try 0219. With a video here:





Quick note: If you want to play games online you need to download and install the update via install package files cause kiosk doesn't download game updates. I just use charles to hijack the links and download them from a second PS3. Or you could boot the game and download them on 3.55 before you copy dev_flash and update to 4.00

Can install retail packages on 4.00 KIOSK firmware, can't mod to run unsigned code yet.. maybe you can?

For those who went to Kiosk and want back to OFW, there's a reverter: [Register or Login to view links] ^-^

I've had one person use this which he went from 4.20 Kiosk to 4.21 OFW with it so... your own risk.
