SOFTWARE UPDATE TO IOS 6 IS STUCK WITH FLASHING APPLE LOGO
i bought a used iphone 4 that is on ios 5. i tried updating the software to ios 6.1.3 but i fell asleep and when i woke up the phone just kept flashing the apple logo every 3-7 seconds. it seems stuck there. dunno what to do next. when i tried connecting to itunes, nothing happens. tried switching the phone on and off but the flashing apple logo still keeps going. is this normal when the software is being updated?
iPhone 4, iOS 5.1.1
