After the release of the new iOS 10 we mentioned earlier, some users started posting problems after over-the-air (OTA) updates they performed on his devices. What does OTA mean? If you download the new functional σύστημα άμεσα από την συσκευή σας και δεν χρησιμοποιήσετε το iTunes για λήψη and installation. 
Τα θέμα που παρουσιάζεται είναι κοινό: Όταν αρχίσει η ενημέρωση αφήνει τους χρήστες μπροστά από μια μαύρη οθόνη που αναφέρει “Σύνδεση με το iTunes.” Το γεγονός αναγκάζει τους ιδιοκτήτες που έμειναν στην μέση της εγκατάστασης να κατεβάσουν ξανά το firmware from their computer and start the installation from the beginning.

The problem of course, the users who did not make the necessary backup before the update have it much larger.
However, as it seems on Twitter, the problem is not observed on all devices.
Apple, on the other hand, claims that the problem has been fixed, according to a tweet of 9to5 Mac.

Users, however, continue to report the problem, so maybe Apple could not even fix it as it claims.
So if you need to upgrade your operating system to iOS 10 today, it's a good idea to make a full backup before you start.
However, the update I made to 6 Plus OTA from 9.3.5 went fine with no problems.
