Advantages and Risks with Unlocked Bootloader
There are quite a few perks associated with an unlocked bootloader. To begin with, you could install custom ROMs or custom recovery like TWRP. Along the same lines, gaining access to the system partition is also a possibility. This is also known as rooting the device, which could be done via Magisk. You could also install Substratum Themes, Magisk Modules, Xposed Framework, and even custom kernels. On the flip side, it comes with a few risks as well.
For example, unlocking the bootloader will wipe off all the data from your device and might even nullify the device’s warranty. Along the same lines, apps like Google Pay, Netflix, and Pokemon GO might face a few issues while working. Not to mention the fact that the entire process might prove to be risky if not done correctly. So if you wish to proceed ahead, then here are the instructions to unlock the bootloader of Xiaomi Mi A3.
