What is iPhone (iTunes) error 2015

Error 2015 is one of many iPhone issues that appears while trying to restore a device through iTunes. The reason why it occurs has no general explanation, but may be related to bugs with software not letting your iPhone establish proper communication with iTunes. Victims of this error receive a stop message saying “The iPhone could not be restored. An unknown error occurred (2015)”. Some devices get stuck in the boot loop forcing users to see their screen struck in the same place. Such an error may also be faced by other IOS owners like iPad or iPod. Fixing the issue should not be a big problem as long as you know the right tools to use. Follow our guide to use them and restore your device successfully.

1. Ensure your iTunes and macOS are up-to-date

Many software-related problems are fixed simply by downloading fresh updates released by the developers. If you are facing an error while updating or restoring a device through the cable, we advise you to check if there is any later version of iTunes and macOS that can be installed. You can do it via the steps:

To install updates for macOS:

  1. Go to Apple menu in the top left corner of your screen and choose System Preferences.
  2. Then, click Software update and choose Update Now to install the latest update available for your current version.
  3. If you don’t see this button, this means your system is already up-to-date.

Usually, other apps like iTunes get updated along with installing the latest macOS version. Even so, it is still worth checking yourself.

To install updates for iTunes:

  1. Open App Store from the dock on your screen.
  2. Move to Updates on top of the window or left pane and search for iTunes from the list.
  3. If there are any updates available, you will be able to click on Install to get them.

Otherwise, your iTunes service is up-to-date.

2. Check your USB cable

When restoring or updating a device through iTunes, there is a chance the connection cable is damaged or badly connected. Try to look over its physical appearance for visible damage and replug it again. Make sure you plug the cable into native PC or Mac USB ports. Avoid using USB hubs and other external devices. If you remember having problems while charging as well, maybe the problem is found. Try using a different cable compatible with your iPhone, iPad, or iPod. The same problem could be with your USB port on Mac itself, so make sure you check it as well. If the cable and USB port seem fine but you continue being struck by the error, follow other solutions below.

3. Force your device to restart

If the process seems stuck and does not show any signs of moving forward, you can force restart your device by clicking a couple of buttons to initiate updates or restoration again. This is how:

iPhone 8 or later:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Press and hold the Side button (which you use to unlock your screen) until you see the Apple logo.

iPhone 7, iPhone 7 Plus, and iPod touch (7th generation):

  1. Press and hold the Side (or Top) button and the Volume Down button together at the same time.
  2. Likewise in the previous steps, the Apple logo should appear on the screen.

iPad models with a Home button, iPhone 6s or earlier, and iPod touch (6th generation) or earlier:

  1. Press and hold both the Side (or Top) button and the Home button until you see the same Apple logo as it was above.

iPad models without a Home button:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Then press-hold the Power button and wait until the iPad restarts.

Basically, the pattern of restarting your device is the same only varying by a combination of buttons on different generations of IOS devices. After successfully restarting your device, try to go through the same update or restore procedure again.

4. Try using another computer

If you did not manage to sort things out using the methods above, try to borrow a Mac from your friend or other family members to update/restore the problematic device. This method is worth trying because you never know what is the problem with the Mac itself. It is also possible your USB port is damaged as mentioned above, which you are unable to see without sufficient experience. Therefore, give it a shot using the Mac of somebody else.

Summary

Error 2015 has been a problem more oriented on older IOS devices. Even so, some users continue to use them and stumble upon similar issues while trying to restore or update their devices. We hope this issue is no longer a center of worry and not a reason why you are not able to use the device as usual.
