Iphone 5s connect to itunes! Help!

So i just got the iphone 5s and i came home to back it up and when it finished i updated it but it gave me an error and sent me into recovery mode… I tried DFU mode already and my computer wont recognize it! I also fixed the administrative tools thing for phones. I need help! Thank you.

You should seriously contact apple chat directly, since you just bought it, they should be easily able to help you with your warranty.http://store.apple.com/us/help/contact
