The iPhone is stuck on the logo - Full usage memory
The iPhone is stuck on the logo. The memory state of the iPhone is full. After connecting to iTunes in an attempt to back up the data. iTunes performed a process of updating the operating system when there was not enough free memory.
Since iTunes fails to complete the system software download process it only allows me to boot to factory mode i.e. delete all the data on the device.
What can be done to avoid deleting the data?
