I was just wondering, as long as I back up the firmware of my player, do I have a perfect chance of recovering it if it becomes corrupt by updating the firmware? Because I JUST got my new one today, after ditching the old one which I was unable to recover after updating the firmware. I don't want to go through all that again.

Also, would changing the theme of my player possibly damage my firmware? I'm treading carefully now. I want to customised my player, but I just got it today and don't want to destroy it already!
