Update data download procedure

  • Create a folder on the storage media in which to save the update data. Using a PC, create a folder named “PS3” on the storage media or USB device. Within the PS3 folder, create a folder named "UPDATE".
  • Download the update data and save it in the "UPDATE" folder created in step 1. Notice: Be sure to save the update data as noted below. If the data is not saved in the correct way, the PS3™ system will not recognize the update data. The folder name must be in all uppercase letters.
  • Location: Save in the “PS3” folder > “UPDATE” folder
  • File name: Save as file name “PS3UPDAT.PUP”.

Update procedure

Notice: Do not turn off the PS3™ system or remove the storage media or USB device during an update. If an update is cancelled before completion, the system software may become damaged, and the system may require servicing or exchange. During an update, the power button on the system front and PS button of the controller are inactive.

  1. Insert the storage media or USB device that contains the update data in the PS3™ system.
  2. From the home menu, select (Settings) > (System Update), and then press the x button.
  3. Select [Update via Storage Media], and then press the x button.
  4. The system automatically searches for and finds the update data saved on the storage media or USB device.
  5. Start the update.
  6. Press the button to start the update. Follow the on-screen instructions to complete the update.
  7. Confirm that the update was successful.
  8. After the update has been completed, go to (Settings) > (System Settings) > [System Information].
  9. If the [System Software] field displays the version number of the update, the update was successful.


You can delete the update data from the storage media or USB device after the update has been successfully completed.

Note: Before proceeding with your driver installation we suggest you make sure you are installing the latest version available and for the appropriate model/revision and Operating System. We strongly suggest following 'readme' instructions for installing drivers when available. Often restarting your system will be necessary for the new driver to become active and start functioning properly.
