first post and I'm much more of a car guy than an electronics guy - Sorry

I have a UN55H6300AFXZA. In the US it comes with the PVR disabled and I want to enable it.
I have read through the E and F sections on PVR and also the wiki, using the info posted there on PVR I upgraded my samsung tablet to send out the factory and 3 speed signals and I accessed the general service menu through mute, 1, 8, 2 pwr and then sent the codes for factory and 3 speed (first time scared the crap out of myself as the screen just flashed white, red, green, orange over and over but a bit more reading got me out and I pushed the buttons faster after that)
I found the PVR enable command line and changed it to yes from no and I turned off the OTN and exited the menu and restarted the TV.
I plugged in a small hard drive and tried the record button but it still says disabled.
I know I followed the E and F directions so I must have missed something for the model H TV - can anyone point me in the right direction please and preferably with very simple words as I am a noob at this.
thanks very much
