Risk level

Proceed carefully and stop if the check is unclear.

Urgency

Medium

Quick answer

The PS5 may have a problem reading the system software or application data. Sony's fix is to update the system software to the latest version, from Settings or, if that fails, from a USB drive in Safe Mode.

Safety first

Stop and check this first

  • In Safe Mode choose Update System Software, not Reset PS5 or Reset PS5 (Reinstall System Software): Sony says both delete all user data.

Safe checks you can perform

  • Check the system software version
  • Update from Settings
  • 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. Check the system software version

      No special tools

      Who:
      you.
      How:
      go to Settings > System > System Software > Console Information.
      Result that matters:
      whether Up to date is shown under the version.
      If it is not up to date:
      update it.
      If it is up to date and the error continues:
      contact PlayStation Support with the version shown.
      Evidence to keep:
      screenshot of Console Information.

    2. Update from Settings

      No special tools

      Who:
      you.
      How:
      go to Settings > System > System Software > System Software Update and Settings and select Update System Software. If the download sticks, press the PS button, open Downloads/Uploads, select View Error Info and then Try Again.
      Result that matters:
      whether the update installs and the error stops.
      If it installs and the error stops:
      outdated software was the cause.
      If downloads fail several times:
      update from a USB drive.
      Evidence to keep:
      version before and after, and any download error shown.

    3. Update from a USB drive in Safe Mode

      No special tools

      Who:
      you, with a PC or Mac and a USB drive formatted as FAT32 or exFAT.
      How:
      create a folder PS5 with a folder UPDATE inside, save the file from PlayStation's PS5 update page there as PS5UPDATE.PUP, plug the drive in, start Safe Mode by holding the power button until the second beep and 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 download on the console was the problem.
      If the file is not recognised:
      check folder and file names in uppercase. If it still fails, contact PlayStation Support; the code alone does not prove a broken part.
      Evidence to keep:
      photo of the drive's folder structure and any Safe Mode error.

    Sony shows CE-106485-4 on PS5 when there may be a problem reading the system software or application data, and its only step is updating the system software to the latest version. Sony's PS5 update guide adds how to update from Settings, how to retry a stuck download and how to update from a USB drive in Safe Mode.
