I tried to solve this problem so many times. But I really can't do it.
I did many step follow instruction in this site.
I ever asked Apple store to backup for me but they rejected.
I really don't know what should i do now.
I really want to fresh upgrade to IOS 9 because my phone is not work well now.
THANK YOU
iPhone 6, iOS 8.4.1
I've had problems with iTunes ever since upgrading to Windows 10. I have had this particular problem since updating iTunes to 12.3. I have not been able to sync since the update.
Me to, every time i try to synch my iPhone 6 Plus with iTunes on my MacBook it crashes. 😟
I've also had this problem since I've upgraded to windows 10. If I unplug my iPhone or iPad from USB and plug it back in, it works - for a little while. Then it stops again. I can't say this is an iTunes issue due to their being no windows 10 blessed version of iTunes. USB syncing has become as unreliable as wifi syncing. Good luck getting anyone at apple who isn't leashed to a script.
IPHONE: sync session failed to start
