Attempting to restore a new phone where the backup was in IOS 10.2 beta 1,2, or 3 using iTunes gives the error "iOS version too old"
Mac mini, OS X Mountain Lion, Problem in Installation, Download
You need to be on the same or higher. As the beta is higher the only way to get a restore done would be to set the phone up as a new phone, enrol in the beta program and perform a iOS update to the latest version. Then wipe the phone and restore from iCloud.
Apple has a support article about similar problems here (Restoring from an iTunes or iCloud backup when a later version of iOS is required - Apple Support) but this doesnt take into account the Beta enrolment as it is a "unsupported" software - given how its a beta
Has there been any update to his that you know of? It seems that the reset and erase all content and settings also erases the beta software profile back to the standard one. So still not able to restore from the beta version of the icl backup.
