FAILED (remote: device is locked. Cannot flash images) Unknown Command - ADB Fastboot TWRP LG

In this tutorial I will show you how to fix these error messages. I was having problems myself flashing my LG Phone. I realised a unlock.bin file was required directly from LG. This may save you sometime. Find the links and commands below.
