title: update android rom programmatically
body: <p>I have a requirement that goes like this:
  We have custom Android devices with custom ROM installed on them. I need to be able to install an update for this <strong>custom ROM</strong> through an app.</p>
  
  <p>What I was thinking to solve this problem was to download the custom rom from a server via ftp and then issue "some kind of command" to execute the ROM from my app, but the problem is I don't know what command to issue in order to execute this ROM.</p>
  
  <p>Do you know how can I install that custom rom programmatically?</p>
