Phone shorts out 5V lines on the USB connector, attempts to melt cable

Recently my Stylo has been through the ringer; dropped, had water near it, etc.

I come back from a 6 hour trip to the city, and the phone’s flat dead with no signs of life. I plug it into the charger, and it lights up for 5 seconds and then cuts off with a pop. I soon discover that it shorts out the 5V lines on any USB cable connected; it’s attempted to melt a cable of mine when connected to a high power 5V output source. Could anyone attempt to repair this device in it’s known condition of trying to melt a USB cable?

@devzero number one suspect would be the micro usb port. You’d need to disassemble your phone and take a look at the port and soldering itself. LG Stylo 3 Plus Motherboard Replacement

Post some good pictures of your motherboard and the charging port as well so we can see what you see. Adding images to an existing question

Replacing the charge port would be a decent idea, however I don't exactly want to hold on for this device any longer. Given that when I plugged it in it stayed on for like 5 seconds then just died, I'm putting my bets on some other hardware located further down the chain. Will try and attach photos.
