I'm happy with 4.4.2, I'm happy with my LTE, I'm happy with my Nexus 4.
I'm not happy T-mobile keeps sending me the update notification for 4.4.3. Twrp stopped the last one from loading on my phone but then I got another notification.
Root your phone. In all honesty, though, unless there's an overwhelmingly compelling reason not to, I encourage everyone to take every update, if only for the security and bug fixes.
my phone is rooted and unlocked; when I touched update it booted into twrp and then it stoped. Well I couldn't figure it out how to sideload the update. So when I restarted it it was back at 4.4 .2
