The Safe Mode is a secret menu that contains all the necessary tools to troubleshoot, update, and maintain your PlayStation 4. Here are the instructions to boot your PlayStation 4 in Safe Mode.
Restart Your PS4 in Safe Mode
The Safe Mode should only be used when one is experiencing major problems such as system failures, game error, recurrent errors, or boot issues. Turn off your console and then hold down the Power button until you hear 2 beeps (7-8 seconds). Connect the DualShock 4 controller using the provided USB cable and then press the PS button to access Safe Mode.
