I had the 16GB Moto X before it took an unfortunate spill and left my screen completely fubar. I just received a 32GB Developer Edition in the mail today but I am unable to upgrade to Kit Kat (phone came with 4.2.2). Whenever I go to About Phone > System Updates > I get: "An unexpected error has occured. Please try again later" How do I go about getting the latest firmware on this phone? Verizon tech support was worthless. Thanks!
