Video: PS3 Firmware 4.00 Dev_Flash Dump for Demo / Kiosk Units

78w ago - Shortly after the PS3 Firmware 4.00 Dev_Flash dump by UpSilon I have posted my method and video (below) for PS3 Demo / Kiosk console owners.

Download: PS3 Firmware 4.00 Dev_Flash Dump for PS3 Demo / Kiosk

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?
