Shutting down after accepting firmware update from USB device

Hello,
I have a nearly 6 six years old WD Elements Play Multimedia Drive which I’ve never tried updating until now. I dowloaded firmware updates from https://support.wdc.com/product.aspx?ID=1012&lang=tr#WD_community . After following instructions up to connecting usb device to the media player and accepting firmware update, media player is shutting down instead of restarting itself. Is there anyone experiencing the same problem and what should I do?
Thanks.

Are you sure you’re getting the right firmware for YOUR device? There are TWO models of the WD Elements Play.

Yes, I think so but should I install GPL code too or what is the difference between NTSC and PAL, I couldn’t find in WD player

No, the GPL code is provided for license compliance reasons, but you have to compile it yourself to use it.

NTSC vs PAL is based on the broadcast standard used in your part of the world.
