Sony Xperia Z3 Tethering Error after Update to Android 6.0.1

Once you update your Sony Xperia Z3 to Android 6.0.1, Tethering might break.


It has to do with something related to Operator APN and DNS resolution. The update forces APN resolution to succeed before activation. It’s amongts new tactics of Telecom operators tyranny. Anyway:

  • Enable Development mode on your Smartphone (CGo to Settings -> Phone Details -> Click several times on Build Number)
  • On your Ubuntu 16.04, install Android SKD along with ADB and fastboot (sudo apt install android-tools-adb android-tools-fastboot -y) (ref: https://www.linuxbabe.com/ubuntu/how-to-install-adb-fastboot-ubuntu-16-04-16-10-14-04)
  • Start an adb shell by typing the following command: adb shell
  • At the adb shell prompt, run this command: settings put global tether_dun_required 0
  • hanine @col in /opt/android-studio/bin (13 entries, 0 hidden)
    7 2005 $ adb shell
    shell@D6603:/ $ settings put global tether_dun_required 0
    shell@D6603:/ $ exit
  • Type exit, then disconnect your phone and reboot
