sprint s7 edge that was unlocked
I have a sprint gs7 edge that was supposedly unlocked. I put my att sim in it and it required me to change the APN info. what I noticed other than the annoying sprint screens, is it never shows the 4g lte icon, and also wont send mms when connected to wifi. should flashing the U firmware rectify these issues? its a SM-G935P, with software version G935PVPU4BQD2 on android version 7.0. I downloaded odin and all the files from the google drive downloader to do it, but im not sure this fixes what im asking for.
