How To Unlock The Bootloader of Samsung Galaxy A70

Unlocking a bootloader on any Samsung device doesn’t require much work, but first, we should understand what a bootloader is and how it works.

What is Bootloader?

A bootloader, also known as the boot manager of a smartphone or a tablet is a small program that puts the operating system of the device into memory. When we power up the smartphone, then the basic I/O of the system processes some initial test which then transfers the authority to the master boot record where the bootloader stays.

Why is Bootloader Locked?

A bootloader is locked on an Android device by the manufacturers for several reasons. The main reason is that the manufacturers want you to stick with their version of Android OS that is highly optimized and also includes some bloatware (generally the brand’s applications). To make sure the apps are not uninstalled and the system runs flawlessly, they lock the bootloader to avoid any future conflicts. This makes flashing custom ROM or custom recoveries impossible and avoids breaking the warranty of the device.

Should You Unlock The Bootloader?

The answer to this question depends on various factors and the user’s choice. If you unlock the bootloader of Samsung Galaxy A70, then you can install a custom recovery such as TWRP, and then you can also root the device. Unlocking the bootloader also helps you flash various types of custom ROM’s that can provide much better performance and stability. In the future, when Samsung stops pushing security updates, then you can install the latest Android version in your Galaxy A70 with the help of custom ROM’s.
