Okay, thank you for confirming. I was thinking that you weren't registered based on all of the information I read from your posts.
I do not know if beta registration is closed or not, unfortunately I have no way of checking myself. I can ask a friend who is also using an unlocked model and not in the beta.
I do know that the beta was based off of a previous build, updating to N975U1UEU2ASJC might be the issue but again, being that I am on the beta, I can't confirm this.
I will let you know if I find anything.
