FIXED: WS-37403-7 error on PS4 [Step By Step]

Do you have a problem with your PS4 and it’s not powering on?

Do you get the error WS-37403-7 when trying to update your system software?

I got this exact error today while trying to update my ps4 from 4.07 to 4.76 via USB, after spending hours researching the solution I finally found one that worked. Plus I will share some more solutions too, in this article.

But before that let us know the reasons due to which this error may occur.

What causes the error WS-37403-7 on your PlayStation 4?

  1. The USB storage device has the system software file saved in a folder other than “PS4” and/or “UPDATE”.
  2. The system software file is on a USB storage device that exceeds the capacity of 32 GB. (The PS4 system supports up to only 32 GB.)
  3. The data protection level on some data stored on the USB storage device is set to “Read-only”.
  4. The system software file for some reason cannot be read on the PS4 or USB storage device.
  5. The applications and features used on the PS4 do not support the version of system software applications and features on the USB storage device.

These are just the major reasons and in most cases, it’s caused by USB storage devices not formatted for ps4 and trying to update them.

So before ringing sony or wasting money on a repair I suggest checking this stuff first.

Fix WS-37403-7 error on PS4

Solution 1: Re-login to PSN and update via a network

Check if you can check for new system software updates and if yes, install the latest version and try updating your console again. (If it fails via network update then follow the steps below)

  1. Connect your PS4 and PS4 controller via USB cable.
  2. Open the settings menu on your PS4 and go to “System Software Update”.
  3. Optionally, select [Notifications] > [Allow Get System Update Notifications]. This allows applications such as system software update notification app (downloadable from PlayStation Store) to check system software updates and notify you.
  4. Make sure your PS4 is connected to the internet, then select [System Software Update]. If a new system software version is available, it will display as [New Version XXXX] on this screen. You can then install the latest version.

Solution 2: Re-format your USB storage device and re-download.

  1. Create a folder to save the update files: Select (Settings) > [System Software Update]. The (Settings) screen is displayed if you’ve turned off your PS4™ system from the function screen, such as when you’re installing a system update using PlayStation┬«Store. Otherwise, go to step 2.
  2. Create a folder named “PS4” on your USB storage device, and then create another folder inside the “PS4” folder. For example, create folders named “UPDATE” and/or “PS4UPDATE”. This folder is where you’ll save the update file for PlayStation™Store games, saves, themes, screenshots uploads, and other data.
  3. Save the downloaded update file in your PS4UPDATE folder. The file must be saved in .PUP (or . PKG) format to install system software version 4.76 the following way: the filename must contain “PS4UPDATE”.

Solution 3: Update via Network Console offline or through USB.

  1. Make sure your PS4 is connected to the internet, then select [System Software Update] from the function screen.
  2. If a new system software version is available, it will display as [New Version XXXX] on this screen. Select (Download).
  3. Follow the screens to complete the update process. (Your ps4 must be updated to PS4 4.76 for this to work)

Solution 4: Reinstall the System software update files via USB storage device

  1. Delete any updated file (PS4UPDATE.PUP) from your USB storage device and make sure you take a backup of it in case you need it later or create a new folder.
  2. Insert the USB storage device into your PS4 and then go to, Settings > System Software Update > Update via Storage Media. Follow the screens to complete the update process. (Your ps4 must be updated to PS4 4.76 for this to work)

Solution 5: Downgrade Firmware

  1. Restore your ps4 to factory defaults via safe mode (Hold the power button on the console until it beeps twice, then select option “Restore Default Settings” and “Yes”)
  2. Delete the update file (PS4UPDATE.PUP) from your USB storage device and make sure you take a backup of it in case you need it later or create a new folder.
  3. After restoring your ps4 to factory defaults, download and install 4.76 OFW via network console (Updates under system software section). You can check the console version by going to Settings>System Information.
  4. If the downgrade was successful, you’ll see the “PlayStation” text logo on your ps4’s screen while booting up. Now delete the system update file downloaded in step 3 via XMB or PC/Mac using SFTP software (You can use WinSCP for Windows or CyberDuck for Mac)

If the downgrade was successful, you’ll see the “PlayStation” text logo on your ps4’s screen while booting up.

  1. After deleting the system update file, re-download and reinstall the update file via USB storage device (PS4UPDATE.PUP) following the same method as mentioned in Solution 1.
