Two iPhones will not sync with computer?

My sister and i both have iPhone 5s and we're trying to transfer our pictures directly to the computer. A couple of days ago I plugged mine in and transferred and all was fine. Well today I use the same cord i used a few days ago, that charges when plugged into the wall, and it will not work. It will not bring up the open files folder or even charge it. I would say it is something wrong with her phone but it will not work with mine now either. I have tried other cords on both phones and neither will work now.

Added (1). When i said 5s I meant 5's as in two iphone 5 not the 5s

5… 5s… Doesn't matter… S = Same old SH#T… Nothing new!

anyways… Reboot the phone and computer… Work now?

if not, hard reboot phone (home+power keys together until apple logo appears) and computer… Work now?

if not, call Apple or see Applestore, you have major software issues…

I have an iphone and ipad, sometime, i wanna transfer videos from iphone to ipad or from ipad to iphone. Now, i'm using anymp4 iphone transfer, it help me solve this trouble. You can have a try.

  • Two songs will not transfer from my computer onto itunes like all the others did? Okay, so I checked google and it was no help. I recently upgraded from my optimus smartphone, to an Iphone 4. Now I was able to get all my music onto my computer from the old SD card, and then I was able to transfer the songs onto itunes, then onto my phone. Then i found out that two songs, two i love the most mind you, will not transfer, I drag them over like i did with the others but they won't appear in itunes, why?
  • Two different computers, two different iTunes.can I use the same Apple ID? I have iTunes on my computer that I use for my iPhone, and my mon just got an iPod Touch and wants me to fill it for her. I'm going to use her computer to do this, which currently does not have iTunes. Once I download iTunes, can I use my own Apple ID to download songs and apps onto her iPod? Is it possible to do that without disturbing what's on my phone, or do I have to make a whole new iTunes account for her?
  • Is there a way two record two instruments into an iPhone? I was planning on playing a duet with a friend where I'm on the guitar and they are on the violin and it's just something I want to post on Instagram, nothing special. Is there a cheap device or method that I can record both of us as we're playing directly into my phone?
  • Is a two year contract actually two years? I just recently got a new job that will allow me to splurge a little bit and finally upgrade my phone. I hope to switch from Straight talk over to AT&T so i don't have to continue paying $300+ when I need a new phone. The iphone 6 is about $100 with AT&T s two year contract, and then I'm eligible for an upgrade. Will I be held in that two year contract or would I be able to upgrade earlier to a more recent version? How much does it generally cost to upgrade early?
