Usb uses 2pins and ground for communication, I don't remember the number assignments. If either the TX or RX get intermittent, you cant communicate. Except for selling her soul to google, google drive did wonders transferring ALL my wife's junk data phone to phone and then also to the laptop. It partially changed some settings in the new phone to be like her old phone.
I have some success getting a new cord. For one or two attempts, but it isn't reliable
