Introduction
OEM unlock is a feature that allows you to unlock the bootloader of your Samsung device, which is a prerequisite for rooting, installing custom ROMs, or modifying the system. The bootloader is a program that runs before the operating system and controls how the device boots up. By default, most Samsung devices have a locked bootloader, which means that you cannot flash any custom images or partitions to your device. This is done for security reasons and to prevent users from damaging their devices.
However, if you are an advanced user who wants to customize your device beyond the official firmware, you will need to unlock the bootloader first. This will allow you to flash custom recovery, ROMs, kernels, mods, and root your device. Rooting is a process that gives you full access and control over your device's system files and settings. With root access, you can do things like remove bloatware, tweak performance, install apps that require root permissions, and more.

OEM unlock is not an APK file that you can download and install on your device. It is a hidden option in the developer settings that you need to enable before you can unlock the bootloader using fastboot commands. Fastboot is a tool that allows you to communicate with your device's bootloader via a USB cable and a computer. In this article, I will explain how to enable OEM unlock on your Samsung device, what are the benefits and risks of unlocking the bootloader, and how to root your device after unlocking it.
How to Enable OEM Unlock on Samsung Devices
Before you can unlock the bootloader of your Samsung device, you need to enable OEM unlock in the developer settings. To do this, follow these steps:
Go to Settings > About phone > Software information.
Tap on Build number seven times until you see a message saying "You are now a developer!"
Go back to Settings > Developer options.
Scroll down and find OEM unlocking. Toggle it on and enter your PIN or password if asked.
Select Enable on the confirmation popup.
Congratulations! You have successfully enabled OEM unlock on your Samsung device. You can now proceed to unlock the bootloader using fastboot commands.
Benefits of OEM Unlock
Unlocking the bootloader of your Samsung device has some advantages that may appeal to you if you are into custom development or personalization. Some of these benefits are:
You can install custom recovery like TWRP or CWM, which allows you to backup and restore your device, flash custom ROMs, kernels, mods, etc.
You can install custom ROMs like LineageOS, Pixel Experience, Resurrection Remix, etc., which offer different features, themes, performance enhancements, etc.

You can customize your device's appearance and functionality using themes, fonts, icons, wallpapers, widgets, etc.
You can improve your device's battery life, security, privacy, and performance using various apps and mods that require root access or custom ROMs.
As you can see, unlocking the bootloader of your Samsung device opens up a lot of possibilities for you to enjoy your device to the fullest. However, it also comes with some risks and drawbacks that you should be aware of before proceeding.
Risks of OEM Unlock
Unlocking the bootloader of your Samsung device is not without its consequences. Some of the risks and disadvantages of unlocking the bootloader are:
You will void your device's warranty and lose any official support from Samsung or your carrier. This means that if you encounter any problems with your device, you will have to fix them yourself or rely on third-party developers and forums.
You will lose the ability to receive OTA (over-the-air) updates from Samsung or your carrier. This means that you will have to manually flash the latest firmware or custom ROMs to keep your device updated and secure.
You will expose your device to potential hackers, malware, viruses, and other threats that may exploit the unlocked bootloader. This means that you will have to be careful about what you download and install on your device and use a reliable antivirus app.
You will risk bricking your device if you flash the wrong files or partitions or make a mistake during the unlocking process. Bricking means that your device becomes unusable and cannot be fixed by normal means. This means that you will have to use special tools and methods to restore your device or buy a new one.
As you can see, unlocking the bootloader of your Samsung device is not a decision that you should take lightly. You should weigh the pros and cons carefully and make sure that you know what you are doing before proceeding. You should also backup your data and files before unlocking the bootloader, as you may lose them during the process.
