How to Troubleshoot iTunes errors 1002, 1004, 1011, 1012, 1013, 1014, 1015 while Restoring or Updating iPhone
Quit iTunes, restart your computer and iOS device. Ensure you have proper internet connection. Then, try to update/restore it.
Solution #1: Plug your device directly into your computer
If you have plugged your device into an attached keyboard or USB hub, remove it. Then, try plugging it directly into your computer's USB port.
Solution #2: Check security software
Security software might be preventing iTunes from connecting to Apple servers or devices.
Try to temporarily remove your security software. Some security apps are not easily uninstalled, hence run a cleanup utility to remove it.
The other thing you need to make sure is that do not install more than one type of security software at a time as it might create trouble for your computer.
Solution 3: Update iTunes
Make sure you have the latest version of iTunes installed on your computer. The old version of the software is known to throw plenty of tantrums; especially when you are trying to sync, restore or update your iOS device. Your computer might require OS X Mavericks 10.9.5 or later or Windows 7 or later.

Solution #6: Use Recovery Mode
Just in case you encounter, error 1015 or get a message that “the required resource can't be found,” it's likely that your device has unauthorized iOS modifications. You might also face this issue while installing an earlier version of iOS (downgrading) that’s no longer signed by Apple. (Check out: How to downgrade from iOS 11 to iOS 10.3.2). Try to restore your device using Recovery mode.
Step #1. Connect your device to your computer and launch iTunes.
Step #2. Next, force restart your iOS device.
Simply press and hold the Sleep/Wake and Home buttons at once. Now, you need to keep holding both buttons until recovery mode screen shows up.
On an iPhone 7 or iPhone 7 Plus, you have to press and hold the Sleep/Wake and Volume Down buttons simultaneously. Then, keep holding both buttons until recovery mode screen appears.
Step #3. You will get the option to Restore or Update your device. Select Update.
Now, iTunes will reinstall iOS on your iPhone without erasing your data.
Note: Let iTunes download the software for your device. If the download process takes more than 15 minutes and your iPhone gets out of recovery mode, make sure to let the download process be completed. Then repeat these steps.
Once the Restore process is completed, you can easily set up your device following the onscreen instructions.
I hope the solutions as mentioned earlier have worked in resolving the problem. As they have always clicked for many other folks and me, they may get the job done for you as well. But if you are faced with this error, contact Apple Support.
