What is Unlock Bootloader?

A Bootloader is a code that runs when we turn on our device. This code initializes some hardware and then loads the kernel and ramdisk, and gets the boot process going. So this process is known as Bootloader. The same concept applies to all the technical stuff such as laptops, PC, Smartphones, and any such device.

Every Android OEM manufacturers lock the bootloader even though it is an Open Source. So if you want to try any CUSTOM ROM, it is impossible to load the CUSTOM ROM without the Unlock Bootloader. So Manufacturer made a policy of making the smartphone with an Unlocked Bootloader will void the warranty. They want you to stick with the Stock ROM. Unlock Bootloader allows you to Root your Android smartphone, Flash TWRP, and Custom ROM in a simple easy method.

Warning!

By Unlocking the bootloader, your warranty can void. So take your own risk. We are at GetDroidTips will not be responsible for any bricking/damage to your phone while/after installing this ROM.
