Well after a lot of searching I finally found the official stock firmware / rom V10c for my LG L20. I’d post it, as I’ve noticed plenty of other people having the same trouble updating via LG software updater.
Download the LG L20 V10c firmware on this site. It is highly recommended to always use the most recent driver version available.
CAUTION: I am not going to write out how to flash your phone because it is all over. Any time you flash your phone, you run the risk of bricking your phone. I will not be liable.
