To initialize PS4™ system software, and delete all users and their saved data, select (Settings) > [Initialization] > [Initialize PS4], and then follow the on-screen instructions.
- When you initialize the system software, all settings and information saved on your PS4™ system are deleted. This cannot be undone, so make sure you do not delete any important data by mistake. Deleted data cannot be restored.
- Do not turn off your PS4™ system during initialization. Doing so might damage your system.
- Restoring the settings will not restore the system software to a previous version.
