Don't know how could you to enable this.
Might version change to higher modal like 5500 could enable DLNA but watch out for bricking risk!
Anyway, you can revive TV back at %90.
But you have better to take shoots of service menu...
If your device bricked, you needed to reset all values and you needed to set them back.
So it's better to have shoots of sub menus of service menu before altering modal number.
On the service mode click opcion then model, replace for ud5800 (next in the file), also in control then sound put on in high devy for play movie for pendrives, BUT BE CAREFULL!!! AFTER DO THAT THE CONTROL PANEL DOESN?T WORK!!!.
