The value update .tot file for use with lgflashtools was posted by thecubed, download that. And also go to the fix soft brick thread and download the files there. Use that guide to flash the value pack .tot instead of the regular stock .tot file.
It will say it failed but as long as your phone is booted up and running(which it will be), you should be good to go.
