Firmware file corrupt iPhone issue is common when your iPhone's operating software and iTunes have gone through multiple updates. As a result, the old codes become incompatible. Therefore, your iPhone could not be restored because the firmware file is not compatible or corrupt.

This problem cannot be solved by simply updating your device. Because in these cases, the iPhone could not be updated because the firmware file is not compatible. The following discussion is going to tell you how you can fix this problem.

What Is A Firmware File on iPhone and Why Do the Errors Appear?

The iPhone firmware corrupt error generally occurs because the firmware file is not compatible with the device for some known or unknown reason.

A firmware has become a broader and interchangeably used term in the world of iPhone and Apple devices. Commonly, firmware refers to the phone codes that deal with the cell tower communication for voice and data. It also includes the boot Read-only memory which is essentially a chip that holds start-up information.

Many people use the terms firmware and operating systems interchangeably. However, a more detailed understanding of these matters finds that the two are different. And operating systems can exist independently from firmware.

Usually, the firmware of a phone remains unchanged during use. Whereas, the operating software is updated frequently. Plus, the firmware operates mainly on a low level and has a single purpose. Meanwhile, the operating software works on high-level interfaces and has general purposes.

If your device shows that iPhone firmware is corrupt, then it might mean that you got the wrong IPSW file for your iPhone.

Other causes of this error have to do with an incompatibility between an updated iTunes or iOS. When the iTunes or iOS from your device has gone through several rounds of updating it fails to recognize the old codes because the firmware file is not compatible with the new software.

3Update or Reinstall iTunes and Restore iPhone Again

If you cannot update/restore your iPhone because the firmware is corrupt or not compatible, then try to update or reinstall iTunes and restore your device. This will solve any minor software glitches you are experiencing and put you back on track.

First, make sure that you installed iTunes on your computer. You can download iTunes from the Microsoft store or get the latest version from Apple's website. If you had already downloaded iTunes from the Microsoft store, you probably won't need to update it. Because it would have gone through and auto-update if a new version had been available.

In case you got your iTunes from Apple's store then, you can update it in three very simple steps:

Open iTunes. Choose Help from the top menu bar of the iTunes window.

From there select Check for Updates and follow the prompts that appear on the screen.

update iTunes on Mac

You might also try reinstalling iTunes on your computer. For that, you have to uninstall the existing software first.

Go to the Start-up Menu. Select Control Panel in the right column.

Find Programs and then Uninstall a Program underneath it.

uninstall iTunes

From there select the iTunes files and right-click on them to uninstall them. You have to uninstall all the relevant files. Such as iTunes, software update files, 32 and 64-bit application support files.

Go to My Computer and select the local disk (C:) to check for any remaining folders.

Restart your computer.

To complete your re-installation of iTunes you have to install iTunes again after completely uninstalling it from your computer. Let's see how you can do it.

Download the iTunes installer from the Apple Store.

Save the installer at a location of your choice on your hard drive.

Run the installer on your system. This will open a dialogue box on the screen.

Click Next and eventually you will reach the Terms and Agreement option. Agree to these terms and select Next again.

You will then have to go through a series of installation and setup options. You will determine language, folder location, and default player options during these steps.

Eventually, you will come to Finish Installing. Select this to complete the process.

Restart your computer.

After that, you can solve your firmware corruption error by restoring your iPhone from iTunes again.

4Download IPSW and Update iPhone with iTunes/Finder Again

If you still get the "iphone could not be restored because the firmware file was corrupt" error after updating and restoring your iPhone, then you might have to get the new firmware. You can download the files from IPSW and then manually install them on your iPhone.

Download the suitable firmware files for your iPhone form IPSW.

Setup connection between your phone and PC.

Open iTunes/Finder on your PC.

You will get a prompt on your iPhone screen. Tap on Trust.

Press and hold the Shift key (Windows) or Option key (MAC) when iTunes detects your phone.

Select Check for Update from your PC screen.

Find the folder for the downloaded IPSW firmware files and select them.

Click the Update button and the process will continue and finish itself. You will see a message on the iTunes dashboard that confirms your "Success" and your iPhone will restart.

Restoring your iPhone in the Device Firmware Update mode is the most intense type of restoration. And you can try it when all the major update/restore/restart tricks fail to solve the corrupted firmware file error.

Press and hold on to the Side button (Sleep button) until the screen darkens.

Keep holding the Side Button. At the same time, press and hold the Volume Down button. Hold the two buttons together for five seconds.
