Check and Verify whether your Android Smartphone’s Bootloader is Locked or Unlocked

If you are an Android user then you might came across a term called bootloader, well in simple language bootloader is a code that executes before any operating system starts to run.

In case of Android devices many manufacturers provide their smartphones with locked bootloader which  makes them virtually impossible to install a custom Rom or firmware on those devices, so before flashing any custom Rom or firmware on Android it is necessary to unlock its stock bootloader.

    Ref step2, “connect your device to your PC via USB cable in fastboot mode.” What do you mean by in fastboot mode and how to do it.

    Also can you clarify if the phone needs to be ON or OFF. For example my phone Panasonic P81 is not booting, it gets stuck at logo screen. Will this method work for me?

      Try key press combinations in power off.. Like volume down+ power or volume up+ power….

    After I type in the phone number for “method 1” do I hit DIAL?
    Even without hitting DIAL the number just instantly disappears and does nothing.
