How to Resolve iOS update and restore errors in iTunes

Posted on by

This article and video is a step by step guide on How to Resolve iOS update and restore errors in iTunes.
So I recorded this video to try and go over all the errors that can come up in iTunes.

Some of the Symptoms you might have when restoring your iPhone, iPad, or iPod touch via iTunes are in the form of error codes and alert messages. Most of the time these errors are caused by older versions of software or problems with connectivity, connecting to the Apple servers.

To resolve these problems you can try the following.
Step 1. Update your iTunes to the latest version or even try uninstalling iTunes if your using a PC do a restart and download, reinstall iTunes. To update iTunes on a Mac go into Apple icon and click updates.
iTunes Updates

Step 2. Make sure you OS is up to date. If you are using Windows go into Control Panel and click on Windows Updates. If you are on a Mac click on Apple and then Updates.

OS Updates

Step 3.Check the Anti Virus and security software on your computer. It could be blocking the connection to the Apple servers. In Windows you can generally right click and disable software until you do a restart. And you can turn off the Windows firewall in Control Panel. On a Mac you can System preferences and security and privacy. 123myIT also has a video guide which shows you how to edit your host file on your computer.

The 3194 error video for a Mac can be found here.

This is really important if you are having issues connecting to the following Apple servers.

* Ports: 80 and 443
* Apple servers:
phobos.apple.com
deimos3.apple.com
albert.apple.com
gs.apple.com
itunes.apple.com
ax.itunes.apple.com

* Verisign servers:
evintl-ocsp.verisign.com
evsecure-ocsp.verisign.com

Step 4. Unplug any extra devices that don’t need to be connected to your computer. Only have your Mouse, Keyboard and iOS device connected. Try a different USB port on your computer and try a different cable and if that doesn’t work try a different computer altogether.

USB Cables

Step 5. After updating or installing software its a good idea to restart your computer. When your computer is restarting take the opportunity to restart your iOS device.

Restart Devices

Step 6. By now hopefully you know how to resolve iOS update and restore errors in iTunes. Time to try the restore again and see if you get the same error.

For more information see this Apple article here.

I hope it helps and Good luck!

      • I have this same error. Windows 7 Home Premium Service Pack 1. iPhone 4S. iTunes 12.0.1.26. Both iTunes and Windows are up to date as of this writing. Original Apple 30 pin cable. No other usb cables connected. Have tried restore multiple times. Apple store can’t do it either. Use this same iTunes and Windows to sync another 4s that doesn’t have this problem. Would like to un-stick the original 4s from the reboot process stopping about 3/4 of the way. Thanks!

        • Hi Andres
          Make sure you don’t have a Passcode on the device or that you have allowed the computer to access the phone on the phone itself. Also what versions of iOS are you trying to use?
          Cheers

  11. Hello,

    Hello,
    Recently my son accidentally destroyed his charging port thinking there was rice stuck up inside. I ordered a new port along with a new screen and home button. The screen and home button were my fault since this is the first time I opened an Iphone. I’ve watched many how to videos and have now become an expert(kidding) at taking an iphone apart. When the new parts came in I reinstalled them but the phone is in recovery and wont come out. I keep getting error 14 in iTunes. I’ve seen every theory on how to fix it but still no clue. They are sending me a replacement display since it may be defective since this is one theory I’ve seen. Also I may have screwed it up with the logic board? I’m all out of ideas and any help would be greatly appreciated. Thank you

  26. PLEASE HELP 🙁

    I have an IPAD 2. it was overloaded with apps so I tried to do a restore to factory settings and wipe the whole thing. Upon doing so I was advised by iTunes to update the software to do the restore. I downloaded the current software and plugged the iPad in for the update and restore. It gets about halfway through the status bar and upon extracting the software it stops and says “unable to restore iPad. unknown reasons. (52)” 🙁

    I have made sure iTunes and my macbook software are all up to date as well as tried numerous cords. What can I do to fix this issue. The iPad is currently stuck in iTunes recovery mode.
