Was stuck in a boot loop for about 20min figured out this is how to boot to twrp. Done it again from power off just to make sure it wasn't a fluke for me at least.

Then wait acouple sec and push volume down button and then the power button hold both till phone boots keep holding threw first lg symbol till it boots a second time then release both buttons and press power button.
