Hey. I haven’t seen that error myself,but usually it’s apps that may not restore. If you had multiple iTunes accounts and downloaded different apps from different accounts,it may not have the password for said account and not restore the app. Other than that,there’s not much of a way to know what did and didn’t restore. do you happen to have an iTunes backup? have you tried factory erasing the iPhone and restoring again. fyi,iOS 11 backups ARE compatible with iOS 12,not vice versa. So if you upgrade to 12 now,so it perhaps fixes software corruptions,you can then restore your iPhone. But say you had an iOS 12 backup,and downgraded to 11 in the downgrade period,you couldn’t restore the backup. it could be a backup issue,or software issue. Try to factory erase it and restore again if you haven’t already!
