hello. Let's straight to the topic. I was planning to downgrade my iPhone 5s from iOS 10 to iOS 9.3.5 . But since I know that I can't restoring iOS 10 backup file via iTunes, I wonder, can I backup via iCloud on iOS 10, and after my iPhone downgraded to iOS 9.3.5, it is possible to restore the backup file from my iCloud? I'm sorry for my english thank you !
