I can download the 6.16.211 OTA update. When I try to install it, the progress bar gets about a quarter of the way and then an exclamation mark shows up and when the phone boots up it says the software update failed. I did root my phone in the past but since I don't know a whole lot about that kind of stuff I really only used that to remove youtube from the phone. Other than that, I didn't change or remove anything else. Even then, I still unrooted the phone and reset it to factory condition but the update still won't install. Does anyone have any suggestions? I can't find anything online about someone having the same problem so I'm guessing it's something I may have done. Thanks!
