title: adb command - Marshmallow - change preferred network mode LTE/GSM
body: <p>I am on the 6.0.1 Marshmallow OS and my previous commands to change the preferred network mode are no longer working.</p>
  
  <p>Commands used in Kit Kat worked without issue:</p>
  
  <pre><code>adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "SELECT * FROM global WHERE name='preferred_network_mode'"
  adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "update global SET value=1 WHERE name='preferred_network_mode'"
  adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "select value FROM secure WHERE name='preferred_network_mode'
  </code></pre>
  
  <p>Commands from above entered in this OS result in output:</p>
  
  <pre><code>Error: no such table: global
  </code></pre>
  
  <p>I pulled the database file, which was completely empty:</p>
  
  <pre><code>adb pull /data/data/com.android.providers.settings/databases/
  </code></pre>
  
  <p>Is there any ADB command that I can use to change the preferred_network_mode to LTE/GSM?</p>
