Rooting my LG L90 without computer?

I apparently have the newer software update (D41510e) and this update has managed to patch up rooting capabilities for places like towelroot. I've done a lot of research and tried several other one click rooting applications, but none of them work due to the software update. I don't have a computer to downgrade the software on my phone or to flash my phone. Is there possibly a way to root my phone (for free) even with this software update or something that can downgrade my software so I can root?
