Flashing roms on lg volt 2

I am new to this. I bricked my phone trying to swap out kingroot for supersu. I am stuck at Boost symbol screen at start up. I have an lg volt 2 with lollipop 4.4. Can I flash a different os into it when I goto bring it back to life or do I need to use a stock firmware ? I don’t think that there is any volt 2 firmware floating around out there. I am in a ****ty situation. I’m broke. My phone is broke. And I can’t afford a new one. Any help and advice would be greatly appreciated .
