To everyone if I forget mention please let me know

You need to enter the different boot menus (mainly factory data reset menu and fastboot menu) many times, so I just have notes here on the top of how it should happen

- Download mode

How to enter : Device power is off, hold volume up -> insert usb cable -> should go to download mode

- Factory data reset menu

Hold Power button and volume down button when boot starts. After some seconds (when phone vibrates or LG logo is visible) let go of power button for 1 second, and then click power button. (This caused me the most headaches, as if I were holding the buttons for too long, the device would cut power and reboot)

fastboot mode

- when device is shut down and without usb cable, hold volume down button for few seconds and plug in usb cable
