However, there are some cases that the error 1671 is triggered by other factors. As a result, you get stuck and neither could continue or finish updating or restoring your iPhone iOS on iTunes.

Among other factors that trigger the same iTunes error to show up would include an outdated operating system of the computer you are using, outdated version of iTunes, security software (antivirus), computer bugs or viruses.

The same thing can happen when using a faulty or slow USB hub to connect your iPhone or other iDevices to the computer.

How to fix iTunes error 1671 on your iPhone 7 Plus?

Given the possible causes, you now have some clues on what to work on and where to start when troubleshooting error 1671 on iTunes. These methods however are only deemed generic solutions, which means that they don’t guarantee a definite fix. But then again, any of these methods can still be helpful so you may as well consider giving it a try beforehand.

Step 1. Check and ensure that your computer’s operating system is updated.

The computer’s operating system version matters when it comes to iTunes compatibility and vice versa. Just like other software or computer applications, iTunes also have its minimum system requirements to be met including the OS version of the computer for it to run on.

Step 2. Make sure you are using the latest version of iTunes on your computer.

The iTunes version also matters when it comes to an app’s efficiency and compatibility. Given that your iPhone 7 Plus is running on the latest iOS version, most likely it also requires iTunes or any other apps to be on their later or latest versions for them to work without any flaws. If necessary, download and install the latest version of iTunes for your Windows or Mac computer. Doing so will rule out the possibility of the error being triggered by software incompatibilities.

Step 3. Temporarily disable security software on your computer.

There are some instances when iTunes won’t function as intended due to a security software like antivirus or firewall installed and activated on the computer. Security tools are designed to prevent any form of threats to the computer system. When you connect your iPhone to the computer, any security software installed on the latter device will consider the iPhone among other external devices that may contain some threats. And to prevent such threat to completely penetrate and affect the computer’s system functions, security software will take necessary actions like denying your iPhone from having full access to iTunes. Depending on how a security software is configured, your iPhone may be granted with limited access or no access to iTunes at all. Another important thing you need to consider when it comes to a security software on the computer is to ensure that it is updated.

Step 4. Use only high-speed USB cable/port.

USB cable and USB port also plays an significant role when it comes to using iTunes to update or restore your iPhone 7 Plus operating system. Using a slow USB port or faulty cable can result to a corresponding error when using iTunes to manage your iOS device. Errors that are associated with this factor are already deemed hardware issues that can likely be rectified by using alternative cable or functional ports on both devices.

After completing all the prerequisites and the iTunes error 1671 persists, here are a few recommended workarounds you can try on.

Third Solution: Try to move the hosts file on the computer to another location.

And for some reasons, moving the computer’s hosts file bars the error 1671 from showing up when doing iOS upgrade or restore on iTunes.

Should you wish to give this method a try, disable antivirus or firewall on the computer and then follow these steps:

 

  • Locate the hosts file on your computer.
  • If you are using a Windows computer, the hosts file is usually located in this directory: C://Windows->System32->drivers->etc. Find the file named hosts then drag it to your desktop.

 

If you are using a Mac computer, you can use Finder to search for the hosts file. Here’s how:

 

  • Launch Finder.
  • Select the Go menu, scroll to and click Go to Folder…
  • If you’re prompted with the Go to folder search box, type /private/etc/hosts and then click Go or press Enter on the keyboard.
  • Open iTunes again and retry to restore your iPhone.

 

When the restore successfully completes, move the hosts file back to its original folder or directory.

While there is no definite explanation as to why and how this file works with iTunes, a number of iPhone users have found the remedy and fixed this error by carrying out this workaround.

Fourth Solution: Put your iPhone in recovery mode.

If you are trying to restore your iPhone 7 Plus with iTunes and you couldn’t proceed as you’re prompted with error 1671, then try to restore your iPhone in recovery mode. Here’s how to put your iPhone 7 Plus in recovery mode and set it up again:

  • Force your iPhone to restart. To do so, press and hold the Sleep/Wake and Volume Down buttons simultaneously. Do not release the buttons when the Apple logo appears. Wait for the Recovery Mode screen to appear.
  • When you see the recovery mode screen, release both buttons.
  • If prompted with the option to Restore or Update, select Update if you want to install the latest version of iOS or Restore to restore from a previous iOS backup.

 

When you select Update, iTunes will attempt to reinstall iOS without erasing your data. Just wait while iTunes downloads the entire software for your iPhone. If the download takes more than 15 minutes and your iPhone exits recovery mode, just wait until the download is complete then start all over.

After the update or restore completes, you may then proceed to iPhone setup.
