Same exact thing is happening with my Brand new LG Velvet and my refurbished like new lg K61 after the latest software update.
It was fine until then.
Definitely not hardware dying on both directly after the update.
No idea how to help/fix it.
You go to change it to data transfer and it flashes up and disappears before you can push the button.
If somehow it was the port destroying itself at the time of the update, why would the settings refuse to let you at least select what you want, even if it won't work?

I have, now, 3 LG G7s, model TM-G710TM. I just bought a new one to replace one of the originals that has been damaged. Both of the originals are still able to connect via USB to my PC to transfer files, but the new phone is not, even after doing all the updates. It will charge using the same cable I use to connect the other 2 but does not show in Windows. Also, there is no USB connection option in the Notifications area (on any of them) and when I go into the Developer Options and select USB Connection Options, the screen pops up for 1/10th of a second and disappears so I cannot select a different option (perhaps it is on Charging only but I can't really tell, it's too fast). Oh, and this same behavior happens on ALL 3 phones regardless of whether they are connected to the USB cable or not.
Does anyone have a fix? Thanks. P.S. the original 2 phones were on Android 9 when I set them up and don't remember exactly how I did it, and now upgraded to 10, so either the USB Connection options in Dev were selectable or there was a USB connection notification that I could change. The only other option I know to try (ugh) is to reset the new phone to factory and do one update at a time and see if anywhere during that process I can change the USB connection type. Thanks again.
