Initialise PS4 system and reinstall System Software using Safe Mode

Find out how to ‘factory reset’ your PS4 console using Safe Mode options 6 and 7. These steps delete all user data and reinstall the PS4 firmware.

Initialisation of your PS4 system removes all of the data contained in your PS4 system storage; this process is often referred to as a "factory" or "hard" reset. Initialisation also deletes all users and their data from the system. PS4 Safe Mode option 7 (Reinstall System Software) will also replace all firmware on the system. Selecting either of these options should be considered as the last step when troubleshooting.


How do I start my PS4 system in Safe Mode?

  1. Turn off the PS4 system by pressing the power button on the front panel. The power indicator will blink for a few moments before turning off.
  2. Once the PS4 system is off, press and hold the power button again. Release it after you hear the second beep: one beep will sound when you first press, and another seven seconds later.
  3. Connect the DUALSHOCK 4 with the USB cable and press the PS button on the controller.

How do I initialise my PS4 system?

Performing this step will delete all of the data in system storage (aside from the System Software) including games, user information and applications. Please attempt to back up your save data to Online Storage or an HDD before performing this step. This process will take some time to complete.

  • If you can access the homescreen, select [Settings] > [Initialization] > [Initialize PS4], and follow the on-screen instructions.
  • If you can only access Safe Mode, select option 6 and follow the on-screen instructions.

Does PS4 initialisation delete games?

Yes, but you can redownload your purchased games again from your [Library].


How do I manually reinstall the PS4 System Software using Safe Mode?

  • Reinstallation requirements

    • DS4 controller and USB cable
    • PC or Mac connected to the Internet
    • USB storage device, such as a USB flash drive — there must be approximately 1.1 GB of free space.
  1. Using a PC or Mac, create a folder on the USB named "PS4". Inside that folder, create another folder named "UPDATE".
  2. Visit the system software page and select the 'Reinstall system software' section. Download the installation file and save it in the "UPDATE" folder. Save the file as "PS4UPDATE.PUP".
  1. Ensure that the “PS4” folder is at the root of the USB storage device, and not contained in another folder:
    (D:) > PS4 > UPDATE.
  2. Connect a DS4 controller (using a USB cable) and the USB drive to the PS4 system.
  3. Start the PS4 system in Safe Mode: press and hold the power button, releasing after the second beep.
  4. Select Safe Mode option 7 “Initialize PS4 (Reinstall System Software)”.
  5. Select [Update from USB Storage Device] > [OK].

If your PS4 system does not recognise the update file, check that the folder names and file name are correct. Enter the folder names and file name in single-byte characters using uppercase letters.
