Android Reverse Tethering

Android Reverse Tethering for windows users.

Tethering is the ability to surf on your pc using the 3g of your phone
Reverse tethering is the opposite : surf on your phone using the ADSL of your PC. No Wifi or 3G connection required.

This work only for rooted users and for Windows !!!

Installation :
Unpack the zip file. This zip files contains the windows part, ADB and the android APK.

Before starting the tool :

• You must install drivers for your device.
  If you don't find drivers for your phone/tablet, check the Universal Naked Driver
  Other interesting tool to install Adb and drivers (32/64) : [TOOL] ADB, Fastboot and Drivers - 15 seconds ADB Installer .
  Some screenshots are availables in this thread to install the driver.


• Ensure you have debugging enabled on your phone :

Settings > Applications > Development > USB Debugging > Turn On

• Ensure you have root access AND SuperUser application installed.
  Change the superuser settings (Menu -> Preferences -> Notifications part) :
  Uncheck "Notifications" label to display "Do not show notification when an app is granted Su Permissions"

AndroidTool

The AndroidTool.exe is the windows part



The low level communication tool (ADB) is included in the zip file.
AndroidTool will try to find ADB in c:android-sdk-windowsplatform-toolsadb.exe
If not found he will use the provided one.

The first time you use the program :

• If you want to use another version of ADB, clik "config" and in the first tab enter the path to the ADB


• Select the DNS server to use in the right list. On complex system, some dns can be detected.

Start reverse tethering
Just click “Connect”.
If it's the first time you use the program, This will install the latest android package and the dependencies (busybox and redsocks).
The SuperUser process may ask you to allow “Usb tunnel”



If the android process crash after receiving superuser rights, close the windows program and start again.

The android interface (first tab) will show connections forwarded to windows.
Others tabs are just for debugging. Send the log on this thread in case of problem.

Start your browser
Google chrome will complain that no connection is available. Don’t care. That work.
Firefox , opera and dolphin don’t have problem with that !!!

The current version of the application can’t forward low level ICMP packet (PING).
From Android Os point of vue, there is no internet connection.

Command line prompt :

The windows tool is a "One click" application. Just click the "Connect" button.
But you can add parameters to directly connect when the program start.
Here are the supported commands : Device:xxxx (where xxxx is the device id), Connect, Disconnect, KillAdb, LogToClipboard, Show, Hide, Quit
Parameter sample : Device:123465789 Connect Hide
Create a second shortcut with Disconnect Quit parameters to stop connection and close the application.

Google Market/Play :

This step is optional, required only if you want to download from market.
This will install some low level program.
Don't worry, I didn't brick my phone and tablet during the development.

The Xposed framework author and me are not responsible for anything you do with your phone/tablet/rice cooker.
This work for android 4.X, but an experimental version of the Xposed framework for Gingerbread made by liudongmiao can be found here:http://forum.xda-developers.com/show...4#post44034334 (no support from my side)

• On the windows program, go to tools tab and click "install hack"


• Launch the Xposed Installer (you just installed) on your android and click on "Install/Update"


• Go to the module tab and check the HackConnectivityService (see screenshot below)


• Reboot the phone


• Done!
  This work for market but also for some other programs (some games,skype,hangouts...)

For older android 2.x or 3.x version :
The application want to have an active 3G or Wifi network interface.
Some market applications are tagged "Wifi" only.
To get around this problem, you can activate the 3G BEFORE starting reverse tethering,all the data will goes to the usb.
Tips : You can connect to some wifi hotspot not protected by a key.
It's only when you want to surf that the hotspot ask you a user/password.
But, at this point, we have an 'active' connection. Market download should work after starting reverse tethering.

Not fully working application but work if you install the HackConnectivityService on android 4.x:

• Market download


• Spotify


• Skype. (not checked yet)


• If someone know another one, post a reply !

Troubleshooting
The tool is not compatible with "CrossBreeder" or other tools that change the host file (removing localhost)

If your device is not listed in the "select a device" combobox :

• Ensure Usb debugging is enabled (Settings > Applications > Development > USB Debugging > Turn On). Deactivating and reactivating the Debug mode may help


• The ADB subsystem is sometimes not working properly. Click the "Kill ADB" button (on Tools)


• Your device is perhaps not installed properly. See your device manufacturer. You can download a generic driver from google here :http://developer.android.com/sdk/win-usb.html.


• Windows can detect your device as a "Media Transfer Protocol" (MTP) or "Picture Transfer Protocol" (PTP). When you connect the usb cable, you have a notification. Click the notification to change this parameter. If one don't work, take the another one...

Click refresh or restart the tool to detect your device.
If the connection shutdown often, try another usb cable

Android 4.3 and 4.4 Troubleshooting
Google added some security stuff on this version.
Important : You have to connect your phone/tablet to wifi or 3g at least once after boot before using reverse tethering !!!

Proxy :
There is 2 problems with proxies :

Android 3G proxy. Even if 3g is desactivated, your provider (APN) proxy may still used by applications.
The windows tool is not able to communicate with your provider proxy.
Note that not all providers include a proxy. You must remove it manually.
The tool will give you informations on how to do it when detected.

Corporte proxy. The windows application is not able to traverse proxies.
The good news is that you can use some applications like FreeCap , sockscap and proxifier.
You must start the androidTool from one of these launchers, giving proxy adress and port.
Thanks "edgd1er" for the information.
