The Android bootloader is a Program that loads the Android operating system kernel into the device’s memory, when the device is turned on. It is the first program that runs when the device is powered on, and it initializes and sets up the hardware components and then loads the operating system kernel.
In addition, the bootloader is often used to unlock the device’s bootloader, which allows users to install custom ROMs, kernels, and other modifications to the device’s firmware. However, unlocking the bootloader often voids the device’s warranty and can potentially compromise its security.
