I think you needed to read wiki over and over before trying to revert your TV.
About you CI - CI+ question at other thread(don't continue questions at other threads, or I will delete).
I think there is already explanation at wiki for this. But you can learn this by reading your modal number. If it continue like T2W its CI but if its continue like T2P than it's CI+ (like UE40B7000T2P).
