Some users who restore the effected i Phone or i Pad through i Tunes discover the device is being downgraded to i OS 9.3.5, rather than updating to i OS 10.
If this happens, it may be a good idea to stay on i OS 9.3.5 for a while until the trouble with the i OS 10 update is resolved, or use i Tunes to install the i OS 10 update instead of the on-device OTA mechanism.
However, if updating doesn’t work, it may be necessary to click Restore, which erases all settings and content.
Some users are experiencing trouble installing the i OS 10 software update by way of the Over-the-Air Software Update mechanism.
The problem is not subtle if encountered, the update halts and then displays a “Connect to i Tunes” screen similar to recovery mode, preventing the update from going further.
If the update fails, i Tunes will inform the user that the device must be restored to factory settings, which would then be able to restore from a backup.
Finally, some of the impacted users who are attempting to use recovery or restore mode to restore the i Phone or i Pad may encounter an error 1671 or similar error message in i Tunes, which further complicates the trouble.
