LG G6 - "Charging blocked, moisture detected", would rooting help? When I charge my LG G6, I randomly get the error message "Charging Blocked - Moisture Detected".

I sent it back to LG, but they said I was no longer covered by warranty because the SIM card tray is broken. They said it will cost me $100+ to fix the software, which makes me think that I can fix this by changing the software on the phone.

Would rooting my phone solve this software specific issue?
Try cleaning your charging port. There might be water there.
