My 12-day-old iPhone 6S got bricked -- and I mean really bricked -- during an iTunes plugged-in update today. I was running iOS 9.3.5 with no problems. Plugged in the phone to my PC, iTunes opened and said there was an update to iTunes available (new since yesterday when I last plugged it in). I downloaded and installed that iTunes update, and then I was informed that there was new software for the iPhone 6s, iOS 10. I clicked Update, and after half an hour of doing what appeared to be nothing, I got the message that the phone couldn't be updated. I was asked if I wanted to restore the phone to the previous OS. I clicked restore. Another half and hour of it doing nothing, and then I was informed that there was an error and the phone couldn't be restored, and it was dead. Unplugged it from the computer, and the phone was not even recognized when I tried to run the diagnostics in iTunes. Verizon was unable to help. I had to take it to an Apple store where they used a "Golden Copy" of iOS 10 to revitalize the phone. My iTunes backup did the rest. But this was an avoidable and completely inexcusable waste of an afternoon for me, and from I can tell countless other people.
