Ans: This option is under developer options. It allows users to unlock the bootloader
How do you unlock an OEM?
Ans: Check out our guide: How to Enable Developer Options, USB Debugging and OEM Unlock on Android
Is bootloader unlock safe?
Ans: It is safe but you have to follow the guide carefully or you may end up bricking your device. The process will erase all your device data and will void the warranty of the device.

My Videocon z51blaze 5.0 unlock bootloader and not show OEM setting
this thread says it works with all android devices yet… my z958 will not boot into fastboot mode in any way… adb reboot bootloader… adb reboot fastboot… both just reboot the phone normally… adb reboot recovery works and recovery has an option to reboot into bootloader mode… guess what happens when I choose that option… the phone reboots right back to the os instead… any workaround for a phone that just doesn’t give the user access to the bootloader at all?
Same with my LG Rebel. Shows ADB Devices but no fastboot devices shown. Does nothing at all.This sucks for us.

Does Samsung grand duos (gt 19082) have bootloader unlocked
You have to unlock it manually. As it is an older device. You should check the updated guide. Sadly we can’t guide you as we don’t have the device in the office. But a simple google search can help. Samsung devices have different methods.
