IPhone can't restore after 10.2.2 iPhone software update?

Hello, has anyone had problems with iPhone after installing iPhone software 10.2.2?

I tried to sync my phone last night to update my calendar and was asked to update my iPhone software, so I did. Then suddenly it said my phone was in restore mode. But no matter what I do (re: their troubleshooting steps), I can’t even restore it. Now my phone just won’t turn on.

Anyone had a similar problem?
