HTC One AT&T Android 4.3 RUU

This update brings the new HTC Sense 5.0 UI and fixes for previous bugs. It is always ideal and highly recommended to have  flashed the latest firmware on your device  to boost better performance and system stability.  I also highly advice to most HTC One advance users that you should have a copy of the official RUU, since it is very useful just in-case if you need to restore back your device to stock from custom ROMs, as well as your last resort for fixing soft-bricks if you messed-up from tweaking.
