iPhone users occasionally run into a strange error – the 4014 / 4013 – that prevents you from upgrading to latest iOS version via iTunes. Barring OTA updates, any update that is done through iTunes runs the risk of several errors and one of them, the 4013/4014, is our concern here.

Put simply, the error is hardware related but like all things digital, you don’t really get to fix this one without your share of head-banging. There are a variety of solutions that worked for various people. What we try here is to make sure you don’t go about trying them randomly but in an ordered way. That makes it easier to fix.

How to Fix iTunes Error 4014 and 4013

Before You Start

As always:

  • Use the latest version of iTunes
  • Make sure iPhone has enough space to bring in a new update. A gig or more is recommended.
  • Also make sure the iPhone is not low on battery.

The Real Problem

Error 4014 (or 4013) is usually associated with a hardware problem – a faulty cable, a faulty port etc. On the surface, your iPhone connects to the computer, iTunes recognizes the device but somewhere down the line, iTunes thinks that the cable is not really that good. Or may be the port isn’t.

The first thing you try should be change the USB port to which you connect the iPhone. Next up, change the cable that you use. Arguably, this has worked not for everyone but for a few people.

As an extreme measure, you can also try updating from some other computer which has the latest iTunes installed.

Backing Up and Going Into Recovery Mode

If you are trying to update the firmware without doing a clean restore but running into this error (even after changing the cables), it’s time to cut the chase. This method is usually recommended as the last-thing-to-try but I think it’s easier to get this done with right away.

  • Connect your iPhone to the computer. Fire up iTunes.
  • Backup your iPhone.
  • Now disconnect the iPhone, quit iTunes.
  • Put the iPhone in recovery mode. The short version goes like this: press and hold power and home buttons till the screen goes blank.
  • Open iTunes on PC.
  • Connect the iPhone. iTunes should indicate (through a dialog box) that an iPhone is detected in recovery mode.
  • Now go ahead and restore the device as new. This will erase everything but you will have the backup to restore from.

Some Notes

  • Occasionally, the error seems to vanish when people update to the last iOS 6.x version and then update to iOS 7. (This applies when you are on iOS 6.0, 6.1).
  • Clear out apps and app memory to free up space on your iPhone. Although this sounds very unrelated to this error, it has helped.

    Have the same with my Iphone 4. Getting 4014 all the time, and it is in DFU mode, Itunes told me that is. Changed from one USB port to another 8 times, yes i have 8 different ports, still no go. Connected to my mac, same problem there both usb ports. Connected to my other desktop with same ammount of ports there, still same thing, and last test i did was on my old vista computer, and got the same thing there, error 4014 all over the line. Brand new usb cable, still no go, and all itunes are up to date, so, what can be the problem then? Tried everything listed from A to Z, nothing helps, so i might take to a apple store and let them have a look as a last resort for this iphone, but i doubt its worth it…

    I have an iPad which I cannot turn on anymore. Everytime I’m plugging it to iTunes, I have an 4013 error. I cannot do an update, neither a restore. Everytime I got the same error and I’m about to giving it up. I’ve try everything: changing the USP port, changing the USB cable, open it on recovery mode, unplugged all my stuff on my computer and more and nothing solve the problem. What should I do now? Thanks.

    I also had this issue with my iPad, error 9 then 4013, I charged my iPad for 10 minutes then tried again and the restore worked. I think the iPad had got too low on power during the restore and was not getting enough power from the computer.
