Computer won't recognize phone; can't restore Neither of my computers would recognize my phone (iPhone 6, iOS 8.3) at all. I've tried everything I can think of, like reinstalling iTunes, trying different ports, trying in safe mode etc., but nothing worked.

So, I tried to put it into DFU mode. Now my computer and iTunes recognizes the phone, but now it's telling me it won't restore. I didn't have No PLS Restore or anything like that installed.

It's giving me different errors every time. I've gotten errors 4013, 2003, 21, and 7. I've tried changing cables and ports, but nothing has worked.

I can get it out of DFU mode, but when I do that the computer doesn't recognize it again.

Does anyone have any ideas for what I can do?
Take it to the Apple store? 

If it's just restoring the phone they shouldn't charge you anything. And after a clean restore you can then try to restore it again at home.
