    How about i dont have that OEM UNLOCKING option down to developer options??? i have a stock galaxy s6

    • If OEM unlocking option is not available then its already unlocked if your phone is unbranded.. If its branded and it supports a carrier then you might have to work around to unlock the bootloader yourself.
