Western Digital TV Live Hub, Firmare Update

(I have a Western Digital TV Live HubWDBABZ0010BBK)

Is the Firmware Ver. 3.12.13 the latest one?
Is 3 years old… from: 7/23/2013

I’m having issues running files, MKV mostly,
What can I do?
Thanks

this product was discontinued and the firmware you have was the last one released for it sadly
anyway you could convert your mkv to avi or mp4

Thanks for the reply.

Do you know is there a chance to tweak a firmware from a similar product?
or a unlicensed one? PM
