Android Studio doesn't see device
Don't have enough reputation to comment but are you certain you've installed the USB driver? If not, start at: https://developer.android.com/studio/run/win-usb.html

Then go to this link b/c you may need an OEM driver: https://developer.android.com/studio/run/oem-usb.html#InstallingDriver

Your above point 8. Try PC Link... doesn't work properly on my PC may be the place to start. Make sure you can connect, transfer files, etc. before moving on the the Android Studio drivers though. I use Motorola phones &amp; always had to make sure their connection worked first.
