For example, whenever you power on or restart your mobile device, you can see a boot screen or logo at first, and then the device boots into the system completely. It’s sort of a code that’s locked by the device manufacturer and comes with a locked bootloader out of the box.
That means you can’t normally flash any third-party firmware or boot file in a locked bootloader until you unlock it. Manufacturers don’t want the user to customize their devices from the system level because it can mess up system files, user data, voids device warranty, trigger privacy issues, etc.
Therefore, you’ll need to unlock the device bootloader first in order to make your handset eligible to successfully install the customization files. Once you’re done with it, you can easily flash the third-party firmware file, mod files, tweak system components, enable root access, install a custom recovery, etc.
Please Note: Not all Android device manufacturers officially recommend or provide methods to unlock the stock bootloader and Google is one of them. So, unlocking the bootloader and flashing custom files on your Pixel devices will fully depend on you. It basically voids the device manufacturer warranty (if any).
