1. Download a file manager with root access like ES File Manager or Root Explorer.
2. Open your file manager and go to:/data/data/com.google.android.youtube/shared_prefs. Find a file called youtube.xml.
3. Edit youtube.xml file using a text editor (long tap and select edit). Find <map> and add these lines just below it.
