A lot of people power on a PS4 and use it for months without restarting it. This can be seriously problematic.

To properly turning off the system, follow the steps below:

  • Hold the power button on your PS4 till it shuts down completely. Make sure the console doesn’t have any residual electricity.
    When the console is off completely, take the power plug out of the socket. Wait a few minutes and let the capacitors drain fully.
  • You should be now able to connect the cord to the power supply and restart the PS4 again.
  • When it’s all booted up, update the system software and you should be good to go.
  • Now, install the update and if you can update without any issues then it was a data corruption thing and it is now resolved. If you are still getting this error though, it might be something entirely different.
