Unable to update the firmware (software) of the Walkman player .

    The following conditions can prevent the Walkman from completing a firmware (software) update:

    • The Wi-Fi connection status is unstable: Update in a 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 make sure it has at least 60% battery charge. If the battery is too low, the power could be turned off during the update and, as a result, the player may not restart.
    • The free space of the internal shared storage is less than 2GB: Before attempting to update the firmware (software), check the capacity of the internal shared storage. Swipe the Home screen upwards and select  (Settings) — storage. If the free space is less than 2GB, increase the free space by transferring data to a computer or another device.
    • The player does not proceed from the system update screen: If the system update is set to Do not allow in the settings, it cannot be updated. Try the following workaround.
      1. Select  (Settings) — Apps & notifications — See all xx apps to show all installed apps.
      2. From the three horizontal dots menu at the top right of the screen, select Show system — System Update — Permissions.
      3. Turn the Storage item to on.
