title: how to get root access in adb shell for unlocking pattern
body: <p>I wanna to unlock my phone then I read some other questions about this subject :
  they say use <code>su</code> or <code>abd shell root</code> and some others like that but they don't work for me </p>
  
  <p>I read an article that say use your settings.db for unlocking but I don't have <strong>settings.db</strong> in </p>
  
  <pre><code>/data/data/com.android.providers.settings/databases
  </code></pre>
  
  <p>or when I want to delete <code>/data/system/gesture.key</code>  I need <strong><em>root access</em></strong> but I don't have any access to root .</p>
  
  <p>what should I do ??</p>
