Look at the bottom sticker of your device to determine its HW version and FW region - details.

After doing that, download the correct FW release, unzip it, upload and upgrade the device FW.

If this was helpful click once on the arrow pointing upward. If this solves your issue, click once the star to mark it as a "Recommended Solution".
