Proceed carefully and stop if the check is unclear.

Urgency

Quick answer

The PS4 system software update failed. Restart the console, use a wired connection if possible, delete the update file from Notifications and run Settings > System Software Update again. If downloads keep failing, update from USB.

Safety first

Stop and check this first

  • Use only the update file from PlayStation's own PS4 system software page. A file from anywhere else is not what Sony's Safe Mode steps describe.

Safe checks you can perform

  • Restart and use a wired connection
  • Delete the failed update file and download again
  • Manual update from a USB drive in Safe Mode

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

    Before accepting a part or repair

    Nothing has been shown yet. Do not accept a part swap based on the code alone.

    Follow these steps

    Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

    1. Restart and use a wired connection

      No special tools

      Who:
      you.
      How:
      restart the PS4 and, if possible, connect it to the router with a network cable before trying the update again.
      Result that matters:
      whether the update now downloads and installs.
      If it installs:
      the connection was the problem.
      If it fails again:
      delete the failed update file before the next attempt.
      Evidence to keep:
      connection type used and the result.

    2. Delete the failed update file and download again

      No special tools

      Who:
      you.
      How:
      select Notifications in the PS4 function area, highlight the update file and press OPTIONS > Delete. Then go to Settings > System Software Update.
      Result that matters:
      whether a fresh download completes and installs.
      If it completes:
      the old file was the problem.
      If downloads fail several times:
      use the USB update in Safe Mode.
      Evidence to keep:
      number of failed downloads and the time of each.

    3. Manual update from a USB drive in Safe Mode

      No special tools

      Who:
      you, with a PC or Mac, a USB drive formatted as FAT32 or exFAT and a controller with a USB cable.
      How:
      on the computer create a folder PS4 and inside it a folder UPDATE. Download the file from the official PS4 system software update page and save it there as PS4UPDATE.PUP. Turn off the PS4, plug in the drive, then hold the power button and release it after the second beep to start Safe Mode. Select Update System Software > Update from USB Storage Device > OK.
      Result that matters:
      whether the console installs the update from the drive.
      If it installs:
      the problem was the download on the console.
      If the console does not recognise the file:
      check the folder and file names in uppercase. If the USB update also fails, contact PlayStation Support; the code alone does not prove a hardware fault.
      Evidence to keep:
      photo of the folder structure on the drive and of any error shown in Safe Mode.

    What it means

    Sony shows SU-30746-0 on PS4 when the system software update has failed. The steps point at the download: an unstable connection (restart and use cable), an update file left in Notifications that has to be deleted before downloading again, and repeated failed downloads, where Sony moves to a manual update from a USB drive in Safe Mode. The code does not say why the download failed and does not show that the console's storage or another part is broken.

    Warnings and stop conditions

    Symptoms and causes

    Probable causes · in order

    • Download interrupted by the connectionPossible

      Sony asks for a restart and a wired connection if possible. If the update finishes on cable, the connection was the issue.

    • Failed update file still on the consolePossible

      The old file stays in Notifications. Deleting it there and downloading again from Settings separates this case.
