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 tablet, is a small program that puts the device’s operating system into memory. When we power up the smartphone, the basic I/O of the design processes some initial tests, which then transfer the authority to the master boot record, where the bootloader stays.
Why is the 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 device’s warranty.
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 the 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 ROMs that can provide much better performance and stability. In the future, when Samsung stops pushing security updates, you can install the latest Android version in your Galaxy A70 with the help of custom ROMs.
