As long as the bootloader remains unlocked, everytime you boot the phone you’ll be greeted with this warning message ” Your device software cannot be checked for corruption. Lock the bootloader.” This is normal you just have to press the power button once to boot the phone normally.

Now that we’ve unlocked the bootloader we’re ready to flash a custom recovery (TWRP) and then root our K20 Plus.
