title: samsung mirrorlink certificate issue
body: <p>I have rooted note 9 android 10.
  I received instructions from a friend to fix the samsung mirror link certificate as below:</p>
  <pre><code> /data/data/com.samsung.android.app.mirrorlink/shared_prefs/Certs_Fetched.xml
  /data/user/0/com.samsung.android.app.mirrorlink/shared_prefs/Certs_Fetched.xml
  </code></pre>
  <p>There may still be a user_d folder. Assign rights.</p>
  <pre><code>chmod -R 660 /data/data/com.samsung.android.app.mirrorlink/shared_prefs/Certs_Fetched.xml
  chown system: system /data/data/com.samsung.android.app.mirrorlink/shared_prefs/Certs_Fetched.xml
  chmod - R 660 /data/user/0/com.samsung.android.app.mirrorlink/shared_prefs/Certs_Fetched.xml
  chown system: system /data/user/0/com.samsung.android.app.mirrorlink/shared_prefs/Certs_Fetched.xml
  </code></pre>
  <p>Certs _Fetched. Xml is this:</p>
  <pre><code> &lt;map&gt;
  &lt;boolean name = &quot;cert_stored&quot; value = &quot;true&quot; /&gt;
  &lt;/map&gt;
  </code></pre>
  <p>but he does not want to help me om how to do it.</p>
  <p>My question is:
  1-how to create Certs_Fetched.xml and how to add it to<br />
  /data/data/com.samsung.android.app.mirrorlink/shared_prefs<br />
  and give it permission as above
  2- in my phone /data/user/0/ I dont hav<br />
  com.samsung.android.app.mirrorlink/shared_prefs I do not know if I need to add the folder
  thanks if you can help me</p>
