title: Read only file system on Android
body: <p>I recently rooted my Droid X and everything seems to be working perfectly. I made some changes to <code>build.prop</code> and when I do <code>adb push build.prop /system/</code> I get the following error: <code>failed to copy 'c:\build.prop' to '/system//build.prop': Read-only file system</code>.</p>
  
  <p>How can I fix this?</p>
