During daily use, the capacity of the hard disk will continue to increase. When the capacity of the iPhone's hard drive reaches a certain level, the iDevice will suddenly shut down and cannot be turned on. 

If you choose Retain User's Data at this time, it will prompt that the device cannot be restored (-1110)
