J'ai eu ce problème. L'assistance SFR ne connait pas ou ne veut pas connaitre les aspects du tethering. Ce qui est sûr c'est que SFR bloque le tethering et donc il faut que le téléphone cache le fait de faire cette opération. Je joins mes notes, prises lors de ma résolution du problème
Bonne lecture

Apres de nombreux essais je viens de trouver un package adb tools et pilotes qui fonctionnent:
http://downloadmirror.co/29Xn/adb-setup-1.4.3.exe
Google made a change in Android 4.4 which allows operators to know when users are using tethering and conveniently block tethered devices from accessing internet.
This can be fixed permanently using the following procedure (UPDATE: no root required):
Enable developer mode (Go to Settings -> About phone, and click on the build number until the developer mode is enabled).
Enable USB debugging under Settings -> Developer options
Connect the device with a USB cable to a computer with the Android SDK platform tools installed
Start an adb shell: adb shell
In the adb shell, run this command: settings put global tether_dun_required 0
exit
Attention, il faut être tres rigoureux sous risque de rendre le smartphone inutilisable

Download the ADB ZIP file for Linux https://dl.google.com/android/repository/platform-tools-latest-linux.zip
Extract the ZIP to an easily-accessible location (like the Desktop for example).
Open a Terminal window.
Enter the following command: cd /path/to/extracted/folder/
This will change the directory to where you extracted the ADB files.
So for example:cd /Users/Doug/Desktop/platform-tools/
Connect your device to your Linux machine with your USB cable. Change the connection mode to “file transfer (MTP)” mode. This is not always necessary for every device, but it’s recommended so you don’t run into any issues.
Once the Terminal is in the same folder your ADB tools are in, you can execute the following command to launch the ADB daemon: adb devices
Back on your smartphone or tablet device, you’ll see a prompt asking you to allow USB debugging. Go ahead and grant it.install adb
Finally, re-enter the command from step #8. If everything was successful, you should now see your device’s serial number in the Terminal window output. Congrats! You can now run any ADB command on your device! Now go forth and start modding your phone by following our extensive list of tutorials!
Some Linux users should be aware that there can be an easier way to install ADB on their computer. The guide above will certainly work for you, but those own a Debian or Fedora/SUSE-based distro of Linux can skip steps 1 and 2 of the guide above and use one of the following commands. . .
Debian-based Linux users can type the following command to install ADB: sudo apt-get install adb
Fedora/SUSE-based Linux users can type the following command to install ADB: sudo yum install android-tools
Just to cover all of our bases here, Linux users may need to put a ./ in front of the ADB commands we list in future tutorials. This is something that is likely known by any Linux user already, but again, we want as many people as possible to understand how to do these tweaks for Android no matter how much of your operating system you know.

MODE OPERATOIRE LINUX
Sur le telephone :
------------------
Activer le mode developpeur : Parametres / A propos du telephone / Cliquer plusieurs fois sur Numero de build
Activer les options pour les developpeurs
Dans les options pour les developpeurs activer le mode Debogage USB
Connecter le peripherique en MTP (cable USB avec le PC + OK sur le tel ...)
Sur le PC :
-----------
# dezipper l'utilitair
$ unzip platform-tools-latest-linux.zip
# lancer l'utilitaire de listage une fois pour lancer le daemon de detection de peripherique
$ cd platform-tools
$ ./adb devices
List of devices attached
* daemon not running; starting now at tcp:5037
* daemon started successfully
56ac62b3 unauthorized
# relancer l'utilitaire de listage pour voir le telephone-peripherique
$ ./adb devices
List of devices attached
56ac62b3 device
# lancer le shell
$ ./adb shell
# sur le telephone, autoriser la connexion si besoin (rebooter le tel si trop de pb)
# consulter la variable "tether_dun_required", la modifier et re-consulter
shell@yotaphone2:/ $ settings get global tether_dun_required
null
shell@yotaphone2:/ $ settings put global tether_dun_required 0
shell@yotaphone2:/ $ settings get global tether_dun_required
0
# sortie du shell
shell@yotaphone2:/ $ exit
# arret du daemon
$ ./adb kill-server
Rappel des commandes sous adb shell :
settings get global tether_dun_required
settings put global tether_dun_required 0
settings get global tether_dun_required
exit
Sur le telephone :
------------------
Deconnecter le peripherique MTP
Dans les options pour les developpeurs enlever le mode Debogage USB
Arreter les options pour les developpeurs
Test partage connexion donnees => victoire !
Pour ne plus voir "Options pour developpeurs" a la fin du menu Parametres :
