USLGOwner,
I too am in the US and have an LG C1. I am also new to this and trying to learn exactly how to unlock something that is 100% capable of DVR. I am not able to see my TV right now but I do believe that you may need to change the area option under the "adjust check". This may be a different button in the service remote if i am not mistaken. I changed it to 1793. This then allowed me to change the toolOPT6 menu to the recommended 273861641. I believe this is where I got stumped and will have to come back too.
I have no idea what the "adjust check / area option" does, if someone could shed some light on the subject that would be helpful.
Thanks to all that contribute to this thread.
Let me know what you get.
