My iPhone isn't updating to the latest iOS update?

Everytime I try to update it goes as far as to agreeing with Terms and Conditions. After I choose Agree, it doesn't do anything, and I've tried resetting and turning my phone on and off but it's not working. Also, everytime I try to update it from my computer it always makes me take it to the Apple Store to fix it.

Maybe your specific iPhone MODEL is too old for the Update you are trying to install.

The iOS Upgrade Description will always tell you what iPhone Model numbers, the iOS Upgrade supports.

And, I do hope that you haven't tried to JailBreak this specific iPhone, and if so, only the Genius Bar Techies at the Apple Store can fix it for you, if you have no friends you can trust.

TIP: If it always tells you to take it to the Apple Store to fix it, why haven't you done that?

  • Will updating my iPhone apps affect my phone speed as how updating the Operating System (OS) will? Currently I'm using the iPhone 5s on iOS 8.3 I know if I were to update my phone to the latest OS I may notice some slowdown on my phone's performance, since it may not have the "muscle" to handle certain functions. Many apps now are optimised for iOS 9 and/or the 6th generation phones. Will my 5s' speed performance slow down if I update my apps? Will the app's performance slow down?

  • Trying to update my iPhone 4 to iOS 7 beta 5, but not updating? I downloaded the iOS 7 beta 5 CDMA file off of ios7stuff.com and I tried updating my phone with the file and my iTunes has been saying "Verifying updated iPhone software" for almost 20 minutes, and my phone screen turned black with the Apple and updating status bar but the update isn't starting. Help! and I do not have a UDID I also have been using iOS 7 beta 3 for a while but it didn't update to beta 4 or 5 which is why I tried downloading beta 5 directly.
