Reinstall OS on LG G4 phone?

[Android Central Question]

I have a LG G4 (LG-H812) and annoyingly I've been having a few software issues. Mainly the "whenever I receive a text message the phone has a visual glitch and restarts" issue.

Of course this just had to start happening a week after my warranty expired. So my provider laughed at me before hanging up, and LG wants to charge more than it's worth...and refused to let me know how to reinstall the OS.

So, is there anyway to reinstall the OS on my paperweight?

Using LGUP and an image of the ROM. Check around in the XDA G4 forums for ROM images and assistance.
