I'm having trouble unlocking the bootloader on my Samsung Galaxy Grand Prime as well. It has no option to allow OEM unlocking and all of the guides explaining how to get it to display don't work for mine. It's an SM-S920L Tracphone running Android 5.0.2. I want to Root it so I can install a custom OS onto it since the current OS is garbage.
