If you are trying to pair your Samsung smart remote to the 360 have you tried Ziggo as the manufacturer and if wants a model then Mediabox Next. Also try Pace DCR7111 that has worked for some users although after a Samsung software update it stopped working, but then some users said it started working again, maybe another Samsung update.
I am trying to pair to the TV basically I had it set up to use the one universal remote, I prefer the Samsung one as it’s smaller more compact. It worked before an update by choosing Pace DCR7111 but not does not seem to work with any.
Does the remote work with the 360 box at all when pairing this to the box? It may very well be worth contacting Samsung to ask why it will not pair with the TV you have
