For over eight years of using Apple products, whether that is a Macbook, iPhone, or iPad, I found these devices actually secured in term of fighting against virus and malware. Do mind that I’ve done a lot of things with it, and the risk of getting at least one virus into the computer or iOS device is very high.
However, that has never happened to me. I wonder if I’m too good at what I was doing, or Apple’s products are generally secured. But when it comes to restoring your iPhone, that’s when a headache starts kicking in. Unlike getting a virus where you can just launch an anti-virus software and remove it in seconds, an error that popup up in iTunes is like a nightmare.
For most users, you may have seen one of these “error code” before; these include 9, 4005, 4013, and 4014. Specifically, there will be a popup saying something like this:
The iPhone could not be restored. An unknown error occurred (9)
The iPhone [device name] could not be restored. An unknown error occurred (4005).
If it happens to you before, I’m sure you know exactly what I’m talking about.
For people who are new to iTunes, this tutorial could be a great resource for you just in case later on you make a mistake or have trouble while restoring or updating your iPhone via iTunes and one of these error shows up.
Fixing Errors When Restore iPhone or iPad
Based on my own experience and research, there is no particular solution to each of these iTunes restore errors; they can be resolved by following one of the following methods below.
Get the latest version of iTunes
In most cases, Apple will notify you when a new update for iTunes comes out. But if they don’t, here is a quick way to check for it.
On your computer, open iTunes and click on iTunes from the menu bar then choose Check for Updates (for Mac OS X only). Windows users can do the same thing, but the option is slightly different. From the menu bar, click on Help > Check for Updates.
Check for Connection between iPhone and iTunes
Earlier this week, we wrote a quick fix for people who couldn’t connect their iPhone with iTunes or have trouble with syncing. Take a look at it and then come back here if that method is useless.
What you can do now is disconnect the USB cable from your iOS device and then plug it back in or try with a newer/different USB cable.
Restart Your Computer and iPhone
If both given solutions don’t help, try restarting your computer and also your iPhone or iPad. On your iOS device, press and hold the Sleep/Wake button until you see the slide to power off option. Drag and carry it toward the right to turn off your device.
To turn it back on, press and hold the same button again until you see the Apple logo. (Also: try the Recovery Mode)
Hopefully, after following what we provided, you can update or restore the iPhone or iPad again, this time with no trouble.
