How to fix iTunes Error 1110 on iPhone 13/12 Pro Max /XR/XS MAX : iOS 15.1
You will see the error 1110 on your iPhone if it does not have enough space to install a system update during the restart. The solution is to free up some space on your device, but if you are in the middle of the issue then you will not be able to free up the space as your iPhone might be stuck in the Apple logo and give an error code 1110. So the only solution available is to delete all your iPhone data and restore the iPhone as new, which most of the iPhone users won’t find convenient. Please note that lots of third party recovery software claim to restore the iPhone with all data, which may be a false claim as this is a new issue introduced in the Apple ecosystem and recovery software won’t be able to handle it.
The issue iTunes error 1110 seems to be introduced in the latest release of the iOS 15 version and we expect Apple to release a permanent solution to this fix soon. There must be a way to free up space from the iPhone in recovery mode. However we always recommend you to take backup on iCloud or other third party cloud service provider as you might be losing important data while stuck in such issues.

Finally the only solution till date is to visit the Apple support centre and ask them for free replacement of the iPhone. But you will not have any of your data if not backed up on iCloud.
