Bootloader Unlocking on Android
A Bootloader is a system code that runs every time before any Operating System starts on a mobile or a computer. It’s worth mentioning that each and every device that runs on an operating system comes with a bootloader. It usually allows instructions to the hardware on a device to arrange the boot sequence whether the device will run the operating system or the stock recovery mode. It basically happens within a fraction of seconds before a boot logo appears on the device. All the bootloaders on Android devices come locked by default from the manufacturer due to security or privacy measures. The manufacturers don’t want to install any third-party file on the devices for stability and security. So, if you want to flash a custom ROM or any other third-party file, make sure to unlock the bootloader at first. Also, Read: Download Galaxy Z Flip USB Drivers, ADB Fastboot Tools and Odin
