How To Unlock Samsung Galaxy A52 Bootloader

In this tutorial, you will learn how to unlock the bootloader on your Samsung Galaxy A52. A bootloader is the piece of code that runs before the operating system. It instructs the phone how to boot up and how to find the system kernel. The bootloader image is always specific to a device because every phone has different specifications and processors.

What is bootloader?

As with any other Android phone, the Galaxy A52 has its own bootloader. There is an issue, however. Samsung has locked the bootloader of the Galaxy A52 for security reasons. If you are an average consumer, you will never care that your phone has a locked bootloader. But if you are a power user that likes to tinker with your phone, a locked bootloader is a big problem. ROMs, mods and custom files are a big part of the Android experience. However, with a locked bootloader, you cannot flash custom ROMs, kernels, or root the phone.

Before you can do any of these, you need to unlock the bootloader of your Galaxy A52. Luckily, Samsung has made it very easy for users to unlock the bootloader, at least on the Exynos variants.

You can unlock the bootloader easily on the Samsung Galaxy A52. You do not need any special tools. The unlocking feature is built-in in the phone.
