Part 1. Things You Should Know Before Enabling OEM Unlock

This section introduces you to the OEM unlock and why you need to have it enabled on your device.

1.1 What Does OEM Unlock Mean?

OEM unlock is an important feature you'll typically find in the Developer's Options section of your Android OS. Before unlocking the bootloader of your Android device, you must first enable it in the Settings menu. As soon as the bootloader is unlocked, you can seamlessly carry out the rooting procedure on your device. The difference between your device before the OEM unlock feature is activated and after it has been activated is that it was initially restricted to just one network carrier at the time of purchase.

1.2 Why Would You Need to Enable OEM Unlocking?

There's a reason Google uncharacteristically kept the OEM unlock feature hidden from the average user. This is because unlocking the feature allows you to evade the initial security check, making procedures such as rooting and custom firmware installation easier.

You cannot install new firmware or root your Android device without first unlocking the bootloader. Unlocking the OEM is also what you need to be given superuser type access, modify the kernel, flash custom ROM or install new modules to enrich your user experience, amidst some other functions.

Part 2. Enable OEM Unlock in Only 3 Steps

This is a very important step you must follow if you don't want to lose any of your valuable data in enabling the OEM to unlock or root.
