LOEWE KLANG 5 SPEAKERS UPGRADE TO WDAL 2.0

MrTepes

Hi :-)
I have a pair of LOEWE KLANG 5 speakers and i would like to connect them to my LOEWE KLANG BAR MR5 through WDAL 2.0

I know that that can be done through a software update with a LOEWE TV in the Service Menu (i have the Bild 7.65)

The thing is that where i live is really difficult to find a Technical service who knows how to do it (they don´t even know about that possibility) so i was wondering if somebody could maybe know where i could find the software so i coud try to make the update by myself.

I know is not a simple process but i´m used to configurate different TVs, computers, etc... and both (TV and Speakers) are out of warranty, so I would like to be able to try it as otherwise I may not be able to use these speakers with my new bar, and I would really like to be able to :-)

If anybody here could help me i would Really Aprreciate it :-)

Thank you Very Much in advance!

P.S: Please forgive me if i wrote something in a wrong way (English is not my birth language:-)
