title: ADB Screenshot: not found?
body: <p>My phone runs rooted 2.3.6 Gingerbread. I write these lines to take a screenshot: </p>
  
  <pre><code>adb shell screencap -p /sdcard/screen.png
  </code></pre>
  
  <p>It says permission denied! So I add <code>su</code>, like this:</p>
  
  <pre><code>adb shell "su -c 'screencap -p /sdcard/screen.png'"
  </code></pre>
  
  <p>Now when I run it, it says "screenshot: not found!"</p>
