I'm on ICS 4.0.4 right now. I inflicted my phone and got rid of safe strap completely . Now that I've done all that I want to update to the new jelly bean. The only problem is halfway through installing it shows the android dead with an exclamation mark Then.it says installation failed. What do i do to get it to work? Do I have to factory reset? Because is rather not but it if will help fissure I will.
