How to Restore an iPhone That Hangs on the Apple Screen

If your iPhone has hung up on the Apple Screen when booting, perform a battery-cycle reboot, or a “reset,” to get the device to fully shut down and load iOS again. Resetting is different from restarting the phone because the device does not fully power down when simply restarting. If the iPhone continues to hang up when you turn it on, the phone can be fixed by entering recovery mode, or DFU mode, and performing a restore. Restoring an iPhone clears all of the saved data and apps on the device.
