What is the PS4 SU-30638-0 error?

What are the causes of PS4 SU-30638-0 error?

If you are getting the SU-30638-0 error on your PS4, one of these causes must be the reason for your case:

Software update can’t proceed due to server issues.

Sony’s PlayStation Network sometimes goes down unexpectedly and if it happens while you’re trying to download the update, the PS4 error code SU-30638-0 may occur.

You can check the PSN server status to know if there’s any declared outage at the moment, or if you need to attempt the update at a later time.

PS4 software blocking new updates.

If your PlayStation 4 software has been modified (modded), the system will automatically block official software updates. While some people are okay with jailbreaking their PS4, we won’t recommend it as that can potentially compromise the security of your console. 

More importantly, running an unofficial PS4 software prevents you from installing the latest PlayStation 4 updates. 

Corrupted PS4 software.

In some few cases, a corrupted system cache or software may be the main reason for your PS4 error code SU-30638-0. You can try to refresh the system cache and see if that will fix the problem.

  3. Wait for 30 seconds.
  4. Turn the console back on and try to see if you can now install the latest firmware.

Install software update via Safe Mode.

If your PS4 is still unable to install the latest firmware updates at this point, the next solution that you can do is to try updating your PS4’s system software via Safe Mode. here’s what you need to do:

  1. Turn off the PS4 completely.
  2. When the device is off, press and hold the Power button. Release it after you’ve heard two beeps: one when you initially press, and another about seven seconds later.
  3. Once the PS4 boots into Safe Mode, connect a DualShock 4 controller to your PS4 with a USB cable and press the PS button.
  4. Select Update System Software.
  5. Select Update using the Internet and confirm again to initiate the procedure.
  6. Wait for the process to complete then restart the PS4.

Manually install software updates.

If your PS4 continues to refuse updating the latest firmware, you can also try to install the latest system software update by doing it manually. To do this procedure, you’ll need to use a USB flash drive or an external hard drive.
