Unhappy [Q] SAMSUNG GALAXY NOTE 3 by AT&T: SM900A, Build UCNC2 - NEED ROOT!

Does ANYONE have an idea when I will be able to Root my SAMSUNG GALAXY NOTE 3 by AT&T: SM900A, Build UCNC2. I have been trolling for a month now and see nothing and have been disappointed to learn that I cannot downgrade in order to Root. So freaking pissed off at AT&T. Don't use Google due to nasty tactics, left Verizon for price gauging and now these guys. Please respond if you know of a site for info to do this or a site where I can sign up for an alert once a solution is found without making it a brick.
