When your PS4 enters Safe Mode, it means that the system has detected a problem and has shut down to prevent further damage. Safe Mode is a special diagnostic mode that allows you to troubleshoot and repair your PS4. There are several ways to get your PS4 out of Safe Mode, depending on the cause of the problem.
One of the most common reasons for a PS4 to enter Safe Mode is a corrupted system software update. If this is the case, you can try to reinstall the system software update. To do this, you will need a USB drive that is formatted to FAT32. Download the latest system software update from the PlayStation website and save it to the USB drive. Then, insert the USB drive into your PS4 and select the “Reinstall System Software” option in Safe Mode.
