How to Enable OEM Unlock Bootloader on Any Samsung Device

In this step-by-step guide, I’m going to show you how to enable OEM on any Samsung phone or tablet device. I will also tell you how to enable it if the option is greyed out or missing in Settings on Android 11 and above, and how to enable it if you’re using a custom ROM.

What is OEM Unlock?

OEM, also known as bootloader unlocking, is the process of disabling the bootloader security of an Android device. It is a requirement before you try to root, flash a custom OS or perform recovery on your phone. The OEM unlock option is available under the Developer Options in the Android Settings app. Please keep in mind that if you install a custom ROM after turning on the OEM unlock on the device, Knox and Samsung Pay will no longer work.

If you’re trying to flash TWRP (custom recovery) or root files using Odin and you get failed errors, it is because of OEM unlock. Before you do that, it is recommended to enable OEM unlock before flashing your phone with a custom file.

Also, please note that Samsung does not allow this option for some of its variants due to security reasons, and some carriers in the US, such as AT&T, do not allow their customers to unlock the bootloader. Some developers later find a way, but if you’re trying it on a brand new flagship, then it’s too early to expect it.

Without wasting any time, let’s move toward the exact steps to unlock the bootloader. Please note that when you enable the OEM option, it will reset your phone to factory default settings and will erase all of your data, including files and downloaded apps, on the internal storage. It is therefore highly recommended to backup your important data before you proceed further. It may also void your phone’s warranty, so proceed at your own risk.

The OEM lock is available under Settings > Developer options. By default, the developer option is not enabled, and you won’t find it. Follow the instructions below.
