[![Fixing Android Tethering Problem for Sony Xperia Lollipop](http://sammy.hk/wp-content/uploads/2015/07/Screen-Shot-2015-06-17-at-12.37.36-pm-1024x845.png)](http://sammy.hk/wp-content/uploads/2015/07/Screen-Shot-2015-06-17-at-12.37.36-pm.png)

Tethering feature is failure after upgrading my Sony Xperia Z to 5.x Lollipop every time. I need to fix it with debug tool ‘adb’ for android development.

If you got Android Development Kit installed, you can run ‘adb shell’ to get debug shell console, and then change the value of tether\_dun\_required in global namespace to 0.

$ ./adt-bundle-mac-x86\_64-20140702/sdk/platform-tools/adb shell
\* daemon not running. starting it now on port 5037 \*
\* daemon started successfully \*
shell@C6903:/ $ settings put global tether\_dun\_required 0
shell@C6903:/ $
