Can't get iPhone 5s to update

Hello. I tried updating my iPhone 5s on my MacBook Air through iTunes and I repeatedly kept getting this error message


It's currently stuck on recovery mode. I've tried holding down the on/off and home button, updating iTunes and my OS, uninstalling and reinstalling iTunes, updating on another computer, and Reiboot. Haven't tried TinyUmbrella yet or getting the ipsw (this isn't a jailbroken phone) but I really want to try all other options before doing a full restore. Anyone have any suggestions to try? Thanks in advance

Hi

Perhaps an Apple Genius Bar Appointment would be one of the next steps if you have a store local to you.

Yes, Thank you! A trip to their store is scheduled.

Try to restore your phone. Try more than once. If nothing happens try on a different computer. If still nothing then I'm afraid you have a bricked phone. Error 1 is a pretty nasty one and has to do with faulty baseband chip. You'll need to tear down your phone to remove and replace it. I'd rather have a replacement phone instead.

Thank you. I did try what you've suggested and I ended up just restoring my phone to factory settings at the Apple store. I did the online Apple chat help and they said that it might need to be replaced, but I'm glad I didn't have to.
