What is the utility of making a GDFS ?

[family]

Have you tried with the new version of Setools? (1.08) Maybe that could help.

The version 1.08 WORKS.
My network and my speaker are back.
"Write GDFS" is now operationnal in setool2 lite. My k550i was off-duty during 3 weeks...
Now it will become a W610i.

Thanks all.
