If you are trying to restore or update your iPhone via iTunes, but you see the error message that “The iPhone could not be updated because the firmware file was corrupt,” you are in the right place.

Here, we will be taking a look at this common problem, sharing with you why you may see this error and what you can do about it.

Let’s start with the reasons you see this error message popup when you try to update your device in iTunes.

Why Is iPhone Firmware File Corrupt?

Although most people may use the terms firmware and operating system interchangeably, it is important to note that they are very different.

The device’s operating system can exist independently of the firmware and while the firmware can often remain unchanged through the life of the device, the operating system is updated frequently.

The firmware works on a lower level of the device’s function while the operating system can function at a very high level.

If you see the error message, “The iPhone could not be updated because the firmware file was corrupt” or something similar when you try to update the device via iTunes, it may be because you are using the wrong IPSW file for your iPhone.

Another major cause of this issue is that the version of iTunes you are using is incompatible with the iOS version on our device.

You may have updated your iOS several times such that iTunes is unable to determine if the old firmware codes are compatible with the new software.

The following are some of the things you can do to resolve this issue:

Remove, Rename or Move the Corrupt Firmware File

One of the best ways to fix this problem is to remove, rename or move the IPSW files from the root folder to a different directory on your computer.

The location of the IPSW file depends on the operating system you are using. Here’s how to find the file on the various operating system:

  • macOS:  iPhone- /Library/iTunes/iPhone Software Updates
  • Windows 10: C:\Users\USERNAME\AppData\Roaming\Apple Computer\iTunes
  • Windows Vista,7 and 8: C:\Users\\AppData\Roaming\Apple Computer\iTunes\iPhone Software Updates
  • Windows XP: C:\Documents and Settings\\Application Data\Apple Computer\iTunes\iPhone Software Updates

remove, rename or move the IPSW files

Restore iPhone with TinyFix Instead

If you can’t use iTunes to restore the device, you should consider using an iTunes alternative that will work just as well, without any of the system errors that you can expect with iTunes.

One of the best tools to use is TinyFix. This is a third-party iOS system repair tool that is also very useful in repairing the most common iOS system issues and also restoring the iOS system to normal function without affecting the data on the device.

You can download TinyFix from the following buttons and then follow these simple steps to use it to repair your device:

Step 1: Open TinyFix on your computer and choose “iOS System Repair” on the main screen.

Pros of Using TinyFix

  • It can fix all iOS issues such as a device that cannot be restored or corrupt firmware.
  • It is fully compatible with all versions of iOS including iOS 15.
  • It is completely safe to use: it will not affect the data on your device in any way and will not damage the device’s system.
  • It is also quite affordable as compared to other similar solutions in the market.

Update iTunes/Finder

Since this problem can be caused by compatibility issues between the version of iTunes/Finder you have on your device and the version of iOS that is on your device, you may want to update iTunes/Finder to the latest version.

To get the latest version of iTunes, open iTunes on your computer and you will be able to see if the version you have is up-to-date.

You can also go to the menu bar at the top of the iTunes window, then choose Help > Check for Updates. Then follow the prompts to install the latest version.

If there are any updates, you should install them first before connecting the device to the computer to see if the issue has been resolved.

Update iTunes/Finder

Disable Antivirus Software and Restart Computer

The antivirus software that you are using on your computer can also interfere with the update process, especially if it incorrectly determines that the firmware file is a threat to the system.

In this case, the best thing to do is to turn off the antivirus software temporarily until you can complete the update process.

You can usually find it under “Settings > Software and Applications” although this may vary from one operating system to another.

Once you have disabled the antivirus software, restart the computer and then try to update the device again.

Reinstall iTunes/Finder

If the problem will not go away even after trying all the solutions above, you can try to reinstall iTunes or Finder.

This is a good solution if the configuration of the current version of iTunes or Finder on your device is not compatible with the firmware you are trying to install on the device.

After reinstalling iTunes, restart the computer and then try to update the device again.


Errors that may occur when you try to update or restore your iPhone via iTunes are very common and usually, they signal compatibility issues between the device and the version of iTunes you have installed on your computer.

So, while this error may seem particularly problematic, the solutions that we have outlined here can help you overcome it and easily update your iPhone.

If you plan to continue using iTunes to update your device, you should always ensure that you have the latest version.
