iPhone 5c after iOS 8.3 Update
My husband has an iPhone 5c. Last night he installed the iOS 8.3 update. This afternoon he was trying to type a text message, but the screen went blue. He was unable to do anything on the phone. Within an hour he was home and told me what had happened. At this point, the screen is black and phone is unresponsive to the home button or the power button. I tried a hard reset by holding the home button and the power button for a minimum of 10 seconds. The phone continuously made a "bong" sound about every 5 seconds. When switching the phone to silent, it vibrates about every 5 seconds. The phone has never had an issue like this before. The phone is NOT damaged and was in a Lifeproof case when issue occurred.
Is there an issue with the iOS 8.3 update?
What needs to be done in order to get the phone working again?
