I recently got the K20 Plus I got an update notification new Firmware https://lg-firmwares.com/lg-mp260-firmwares/ it came out 9/01/17, I won't be doing any updating soon because I have thing to do for at least the next several days but I am curious if anyone has problems reflashing twrp and rooting if they have updated.
I received the notification of an ota firmware update for my LG K20 Plus also but did not take it yet because I dont want to mess up my root/unlocked bl etc. I'm going to sit tight until I see whats up first. I did use the LG Bridge tool to see that there is an update and I can update that way also if I wanted to.
Yep that is the approach I am taking as well. I suspect, but will wait till I have plenty of time to fix if problems occur, that I can use lg's tool to upgrade to the new firmware, I have already downloaded it, then just use fastboot to put twrp back on, then do the superuser zip install
