I'm a little confused:
Do you have a problem with the "new in box" PHR that LG isn't helping you with? It sounds like you didn't actually buy it from them, but is there a problem with it? If so, you should disclose that since you are trying to sell it.
Are you are trying to get help with something unrelated from LG and just getting frustrated? If so, why sell the bar? It's a good piece.
Not trying to kill your sale, or anyone's purchase, but perhaps you should clarify (not vent, just clarify

).
