I've encountered far too many home built PCs that the drivers for the OS were not installed. I see the make, model of the phone but the PC?
But this looks to be an OLD PHONE (2010 is OLD!)
What makes you think it's USB is alive?
when I connect usb cable from phone to pc, nothing happens.
I have downloaded the usb driver update from LG and still the same.
please can someone advise?
