First, I need to make sure I understand what reverse tethering entails. Normally, when you tether your phone to share internet to your computer, but reverse tethering is the opposite. Since USB is unidirectional for Ethernet, it's trickier. Tools like USB Tethering Enabler or using ADB with IP tunneling via USB might be methods. But the user mentions a ZIP file, perhaps a pre-packaged script or app that automates this.
