[Q] Update from unofficial firmware to official
Hi. This may be a dumb question but I'm just learning all about android. Anyways a few months back I installed a leaked version of Android 4.4.2 (Baseband Version I337UCUFMLD) then when AT&T released the official version of Kitkat(Baseband Version I337UCUFNB1), I didn't receive an OTA update or an update via Kies (and never have since). My question is, is there a way to update/flash/install (or whatever) the official AT&T firmware so my phone is "legit"? Also, if I'm stuck on this firmware for now, will I get a OTA or Kies update when Android 4.4.3 (or whatever the next update is) is released?
Thanks for any help.
