Samsung Galaxy Tab Pro SM T320 powered with Android 4.4.2 KitKat
I have a unlocked Samsung Galaxy Tab Pro SM T320 powered with Android 4.4.2 KitKat, and tried to unlock it by your tutorial.
However, for security measures I stopped the process on Step 2 because there is no option ‘OEM unlock’ in Developer mode.
So, I request your help for surpass this issue if you please.
@PauloAlves Sorry for my error! The device is LOCKED and I intend to unlock it.
