Latest firmware W TV Live

WD TV Live
I’ve had to replace the button battery.
Not sure if I now have the latest firmware version. Any deas where can find it?
I’m assuming it can be put on a memory stick and just plugged in???

Pretty Much … search this forum for help if you have problems. There’s a bazillion posts about the topic.

Just can’t find a link to the firmware. Came a cross a download with a .zip extension which, when expanded into a folder displayed a bunch of files with unkown (to windows 10) extensions. Was hoping for the tradionalt ‘setup.exe’ sort of thing.
