Same problem as others I see. Summary tab gone. I bought iPhone 7 plus. Backed up my 6+, set up 7+ and restored from backup. Everything transferred except my music and out of over 2000 songs 297 downloaded. So.... I downloaded the songs from icloud
to iTunes on my computer and was trying to get them from iTunes to the iPhone. I reset iPhone to factory settings and when I tried to log back on to do the summary tab and "restore from backup, there is no summary tab anymore and I can't get to anything to load the music back on iPhone. The same 297 songs appears on ihpone, and the rest of the songs still appear in the iTunes library. Device DOES show on the sidebar and the "restore from backup" is greyed out.
JA: Just to clarify, what's the make and model of your machine, and what operating system are you running?
Customer: iiphone 7+; iTunes is 184.108.40.206;
JA: Have you installed any updates recently?
Customer: iPhone is 10.0.2l The computer added a bunch of updates to Windows before it would restore the restore the phone to factory settings I noticed. I know the iTunes pages look different than before as well, but the smmary screen did say earlier that I was up to date.
JA: What troubleshooting have you tried?
Customer: I don't know much to do. I've been reading other help lines but haven't found anything that addresses my problem. some said there would be an ad that you could close and then summary would pop up - I don't have an ad to close. My side bar is open, so I can see my iPhone device. I tried the sync iPhone, but stopped it because I was afraid the iPhone few songs would overwrite the many songs on iTunes.
JA: Anything else you want the Mac expert to know before I connect you?
Customer: That's probably all I iknow to tell you!
