Why can't I software update?
I bought a Samsung Galaxy S4 about a year ago and got it unlocked for t-mobile. Everything works great but I am unable to do software update. When i try to upgrade it tells me service unavailable. My baseband version and model number is still under Verizon, I tried to change it but don't know how and nothing I tried worked. I have android 4.4.2 and i know that there is higher and better software. Also I really do not want to root my phone to get an update. Any one know how I can get the latest software.
