Among various utilities, search terms like reference legacy software packages, specifically older versions of tools like the Android Reverse Tethering Tool 3.3 .

A 33 zip file is a compressed file that contains software and drivers necessary for enabling reverse tethering on Android devices. The 33 zip file typically contains a modified Android driver that allows the computer to recognize the Android device as a network interface.

Reverse tethering allows an Android device to use a computer’s internet connection via USB instead of Wi-Fi or mobile data. This paper documents the working method using 33.zip , a package containing necessary USB drivers, ADB tools, and scripts that successfully enable reverse tethering on Android 5–12 (tested). The method requires USB debugging, ADB, and GNirehtet or adb forward -based TCP tunneling.

This forces the phone to use the PC's connection. This is essentially what the 33 zip attempted to automate.

Standard tethering turns your phone into a portable modem to supply internet to a PC. Reverse tethering does the exact opposite:

This completely replaces the 33 zip method with a stable, modern solution.

There are several methods to achieve reverse tethering on Android, including using:
