  • In literal terms, bootloader is code that is executed before any Operating System starts to run.
  • Every Android phone has a bootloader that instructs the operating system kernel to boot normally
  • A bootloader is usually locked on an Android device
    • because although it’s an open source OS, still the manufacturers want you to stick to their Android OS version specifically designed for the device.
    • In order to apply this concept, manufacturers lock the bootloader.
    • With a locked bootloader on Android devices, it is virtually impossible to flash a Custom ROM and forced attempts void warranty as well as usually end up in bricks.
    • Therefore, the first step is to always unlock the bootloader.
    • If you want root, you’d be wanting to flash Custom ROM post-root,
      • and if you want to install a Custom ROM, you’d need to have your stock bootloader unlocked.
      • In simple terms Unlocking the bootloader allows you to install custom Firmware on your Android phone.
