Their was a "change" in Cydia and I did the upgrade. After that it says to restart springboard. I tapped it and after I tapped it the iPod went to "shutdown". Where I have to slide it across to shut it down. For some reason every time I load up iPod back on it starts flashing and it goes straight to the shutdown again. If it does load up right it starts flashing again after a while and goes to the shutdown. I don't know how to stop it and to have it running good again. Anyone?
