Le eco le 2 Android 6.0 : How to share my computer internet on my android with USB?
As far as I know, only a few manufacturers include the USB Internet option in the menu.

I was looking for a way to reverse tether my Android devices some time ago as well and eventually developed my own solution. The result is an app that works on devices running Android 4.0 or higher on client side, and all major desktop OSs on the host side.



The app is available on Google Play: ReverseTethering NoRoot
