I can't update the Walkman player software

IMPORTANT: This article applies only to specific products and/or operating systems. Check Applicable Products and Categories for details.

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

The Wi-Fi connection status is unstable 

• Try to update the device 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 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 free space of the internal shared storage is less than 2GB

• Before attempting to update the 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 other device.

The player does not proceed from the system update screen

• Make sure system updates are set to [Allow]. A device set to [Do Not Allow] will impede the update procedure. Try the following workaround:

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