I cannot update the Walkman player software

The following conditions can prevent the Walkman from being able to complete a software update. See each workaround for details:

• An error message appears, indicating insufficient storage space
• The Wi-Fi connection status is unstable
• The battery level of the player is less than 60%
• The player does not proceed from the system update screen

An error message appears, indicating insufficient storage space

The update requires at least 2 GB of free space on the player's internal shared storage (For the NW-A300/ZX700 series, the required free space is more than 4.3 GB). If the available space is less than this value, an error message appears, indicating insufficient storage space.

Note: The image below is an example of the error message screen that may appear when updating the Walkman using a Wi-Fi connection.

If the error message appears, try the following:

1. Check the free space on the player:
   1. Swipe the Home screen upwards.
   2. Select Settings.
      The amount of free space appears under Storage.
      
2. Transfer the data to a computer or microSD card, and make the free space on the internal shared storage 2 GB or more (For the NW-A300/ZX700 series, the required free space is more than 4.3 GB).

The Wi-Fi connection status is unstable

Move to a different location with a good Wi-Fi connection.

The battery level of the player is less than 60%

Update the Walkman while it is charging and has at least 60% battery charge. If the battery is too low, the power may turn off during the update and, as a result, the player may not restart.

The player does not proceed from the system update screen (only for NW-A100 series, NW-ZX505, and NW-ZX507)

If the system update is set to Do not allow in the settings, it can't be updated. Try the following workaround:

1. Select Settings → Apps & notifications → See all xx apps to show all installed apps.
2. From the menu at the top right of the screen, select Show system → System Update → Permissions.
3. Turn the Storage item to ON.
