open failed: EROFS (Read-only file system) android phonegap app

I'm trying to use a Progress event with PhoneGap for file transfers.

My problem is that every time when I press the download button, the errors below appear.

I found the code under this link and copied it completely: http://www.raymondcamden.com/2013/05/01/Using-the-Progress-event-in-PhoneGap-file-transfers

I found a solution, I changed the fullpath to root.toURL() .
