Just try to HARD RESET it.
Press Power Button for 3 Sec, then without Releasing power button, press Home button for 10 Seconds, then release the home button (but keep pressing power button), and press volume up (+) button for 12 more seconds. Once Itunes plug in logo comes, just restore with latest IOS (compatible to your's daughter's Iphone 4).
Note : If it was not backed up, all data will be deleted.
Let me know if it works.
