Plenty of gamers have faced the following frustrating situation with their PlayStation 4 console: after updating the system firmware, the console got stuck when booting, showing an error message.

The full message reads: A serious error has occurred in the system software. The PS4 will restart.

The same happened to users who, accidentally or not, unplugged their PS4 before it was fully powered down. 

There aren’t many options to explore here, since the console is almost impossible to use, however, we’re trying to shed some light into the matter in this article.

How can I fix the serious error has occurred on PS4?

1.Restore to factory settings

  1. Plug your controller to the console using a USB cable.
  2. Press the PS4 power button until the console beeps twice.
  3. The press the PS4 button on the controller to enter Safe Mode.
  4. Here, scroll to the Restore Database option and proceed.a serios error occured ps 4
  5. Allow the process the finish and then try to reboot the console as you usually do.

 This will clear the system of any corrupt files but will also restore the database and will also clear anything you have saved up until that point.

So make sure you have a backup of your files prepared.

2. Reinstall software using a USB 

reinstall ps4 from usb

  1. On a FAT32 USB created a folder named PS4. Inside that folder, create another folder named UPDATE.
  2. Download the installation file from the PlayStation official page, and save it in the UPDATE folder as PS4UPDATE.PUP. (The PS4 has to be at the root of the USB storage device, and not contained in another folder.)
  3. Follow the first 3 steps mentioned in the previous solution to enter Safe Mode.
  4. Here, select  Initialize PS 4, then Update from USB Storage Device and OK.

This applies only if you have a USB with the PS4 software on it; and hopefully, the console will read it. On some occasions, the users complained that the console took a very long time until it recognized the file.
