Instructions
Reaching the System Update Section
Turn off the PS3 by holding down the power button for a few seconds. Then, turn it back on, and wait for the boot up screen to appear.
Connect the PS3 controller to the console using the USB connection cable. Insert the USB Flash card (or other memory device) in the console.
Check that the set-up menu appears on the screen. Using the controller, scroll down to "System Update," and select it by pressing the "X" button.
Reflashing Your PS3
Scroll down, and select "Update via Storage Media."
Confirm that you want to begin the update by pressing the "X" button. Wait for the process to complete.
When it's finished, the system will reboot. Select "Settings," then "System Settings," then "System Information."
The number on the screen should match that of the update with which you reflashed the console.
