So basically my girlfriend did an update of her Android OS today, installed, the phone restarted automatically, started loading something and the loading bar stayed at 3/4 for like 2hrs. So she tried to turn it off using the button but didn't work so she took out the battery. Then after turning it on, the phone stays at the "Hero" homescreen and doesn't do anything. So I was thinking, is there a way to reinstall android on it? If so, where can I download the OS? Thanks if advance
