Hello, everyone. I really need help here. I've posted about this question on many other forums, yet I didn't find an answer. My HTC One is 4.3 running Sense 5.5, and I would love to update it to 4.4. Now here's the problem, the phone can't seem to find an update. My carrier is STC. I have never done any modifying. I know all about rooting but I'd like to stay fully stock on this phone. Is the problem that 4.4 isn't released on my carrier? My dad's S4 got the 4.4 update long time ago and I didn't. Help would be appreciated.
