Replace LG G7 charging port due to water damage

[scandiun]

This is a little explanation of what happened: by mistake splashed with water a USB-C cable suited for charging. Then I connected it to the G7 to charge it, and immediately got the debris/moisture message:

LG System Server
Check USB port
Charging blocked due to moisture/debris has been detected. Make sure the USB port and cable are dry and free of debris before charging.

What I did was, perfectly clean the G7 USB port with Electronic Contact Cleaner, and buy a brand new USB-C cable. However, from time to time, the message still appears sometimes when connecting the charger, and always when disconnecting any USB-C to 3.5mm jack audio DAC, probably this happens because it uses more pins than the charger?

I've contacted LG tech support on my region, and they state they'll perform a device reset and OS update, which I don't want either of them, so my best bet is to try to do it myself. The tech support states an IP Ingress Protection test is required to assure it's up to specs, to discourage me to do it myself, but I've seen tutorials on YouTube and they don't replace the cover seal, so I guess it's still protected?

I'll contact tech support again for repair price, and to know more about the back cover seal issue. Until know they didn't want to tell me how much it is, they want me to send the device over, so it's more likely I don't turn the repair down once the device is there even if the fixing is pricey.

Finally bought a charging port replacement called "OEM USB Charging Charger Port Dock Connector Mic Flex Cable for LG G7 ThinQ G710" from eBay seller smileelife, apparently it's OEM quality and includes the rubber O-ring. Let's see when it arrives how it looks like.

You can choose between two models, LMG710VM and LMG710EM, which is mine.

Replaced the USB charging port, and working perfectly so far so good.

The problem was, I contacted LG, and they refused to give me a quotation on how much the repair will cost. They just require you to send the phone, which implies a factory reset and software upgrade. I've filed a Consumer Complain against LG due to not facilitating repair prices in advance. Let's see what happens and who do they favour.

The reference for the charging port on my phone is the LG EBR85980107, in case it helps somebody.

Thank you very much...however in my case I used normal charger and after that the fast charger,this way the problem solved. fast charging is causing the problem I think! Its a temporary solution though.

Oh I see, I guess you can use iphone wall charger or use a computer. None of them support QC3.0 or similar. Can't test anymore since it's fixed.
