The arrival of a new iOS update is often met with excitement. It promises a plethora of new features, bug fixes, and security enhancements. However, when you see the “software update failed” message on the screen is always frustrating, leaving you wondering what went wrong and how to fix it.

This comprehensive guide explains what might cause iOS 17 software update failed, or even the latest iOS 18 Beta, and equips you with a step-by-step approach to resolving the update issue and successfully completing the process.

In this article:

Part 1. Why iPhone/iPad Software Updates Fail?

New software updates are like fresh deliveries arriving at the docks. Sometimes, though, things can go wrong during the "unpacking" process. There are many potential causes for an iOS 17/18 update failure. If you have an unsuccessful iOS 17/18 software update, then check out these common factors:

If your device is an older model, it might simply not be compatible with the latest iOS 17 or iOS 18 Beta update. Here is a screenshot of iPhone models supporting iOS 18.

If your device is crammed with apps, photos, and videos, there might not be enough space for the update to download and install.

A weak Wi-Fi signal or frequent dropouts can disrupt the download process, making software update failed.

Temporary glitches and bugs on your iPhone or Apple's servers can sometimes cause update failures.

Apple's update servers are experiencing temporary overload or maintenance periods.

Part 2.  Fixes for Failed Software Update on iPhone/iPad

Whether you have identified your problem or not, here we provide 4 effective methods for you to solve the “software update failed” issue. No matter what iOS version you are updating to, they apply to all.

1Check Your Storage Space

Running low on storage space is a common and the most possible reason for a failed iOS 17 software update. Currently, if you are updating to iOS 17.5.1, you need to have at least 1.05 GB on your iPhone for the update to be completed. For iOS 18 Beta, you need to have 7.11 GB at least. So the first thing you should do is to check your settings, if there is not enough storage to update your iPhone or iPad, you’d better free up some storage and make room for the update.

To check iPhone Storage:

Navigate to Settings > General > iPhone Storage (or iPad Storage)

Here you would see how much storage space you have left. If it’s smaller than the size of software update, then here are some suggestions for freeing up space:

    Offload Unused Apps: Offloading an app removes the app itself from your device while preserving its documents and data. Navigate to Settings > General > iPhone Storage (or iPad Storage), tap on the desired app, and select Offload App.

    Delete Unnecessary Photos and Videos: This action frees up significant storage space on your device for the update. You can always access these memories from the cloud storage service if you have enabled iCloud syncing.

    Purchase iCloud Storage: Most iPhones come with some free iCloud storage, but upgrading to a higher iCloud storage tier provides even more flexibility, allowing you to store a larger volume of data.

    Clear Safari Cache and Browsing Data: Your Safari cache and browsing data can also take up space. Clearing them out is a quick and easy way to free up some space. Go to Settings > Safari > Clear History and Website Data > Clear History and Data.

2Check Wi-Fi Connection

A stable network connection is essential for a smooth and uninterrupted update experience. Weak connection is always one of the top factors for a software update failure. Here are some troubleshooting tips to ensure your Wi-Fi connection is up to the task:

1. Connect to a Different Wi-Fi Network:

If you're currently connected to your home Wi-Fi, try switching to a different network, such as a friend's or public Wi-Fi.  Sometimes, the issue might lie with your home router or internet service provider.

2. Restart Your Wi-Fi Router:

Restarting your Wi-Fi router can often resolve temporary glitches or connectivity issues.  It's like giving your router a power nap to refresh its memory and get it back in top gear.

3Delete the Downloaded Update

The “Software Update Failed” screen often appeared after you download the software and somehow fail to install it. To install the software later, you need to delete the downloaded update in advance. Here is how:

Open the Settings app on your iPhone or iPad.

Scroll down and tap on General.

Look for the option iPhone Storage (or iPad Storage).

Find the Update option and tap on it.

Look for an option labeled "Delete Update" or something similar.

Go back to the Software Update section in Settings and tap on "Download and Install" to initiate the iOS 17/18 update process with a fresh download.

4Force Restart Your iPhone/iPad

While a regular restart can sometimes resolve minor glitches, a force restart can be more effective in certain situations. A forced restart method effectively reboots your device, clearing its temporary memory and potentially resolving software issues that might be hindering the update process. The forced restart method varies depending on your iPhone or iPad model.

For iPhone 8 or later (including iPhone SE 2nd and 3rd generation):

Quickly press and release the Volume Up button.

Quickly press and release the Volume Down button.

Immediately hold down the Side button. Don't release it even when you see the Apple logo appear.

Keep holding the Side button until the Apple logo appears again. This might take a few seconds longer than during a regular restart.

Once you see the Apple logo for the second time, release the Side button. Your iPhone or iPad will complete the restart process and boot up normally.

For iPad with Home Button:

Press and hold the Top button on the top of your device. Don't release it even when you see the Apple logo appear.

Keep holding the Top button until the Apple logo appears again. This might take a few seconds longer than during a regular restart.

Release the Top button once seeing Apple logo.

For iPad without Home Button:

Find the Top Button (top right corner) and either Volume Button (side).

Quickly press and release a Volume Button (Up or Down).

Immediately hold down the Top Button at the same time.

Ignore any slider and keep holding both buttons for a few seconds.

The screen will go black, and then show the Apple logo.

Let go of both buttons when you see the Apple logo.

3Update iOS 17 Software via IPSW Firmware

Here is how you do it:

Connect your iPhone to your computer. Launch iTunes (Windows) or Finder (Mac).

In iTunes, it should appear on the left side. In Finder, it might be on the desktop or sidebar.

Hold and Click "Update": Here's the key part:

Windows: Hold SHIFT on your keyboard and click "Update" in iTunes.

Mac: Hold OPTION on your keyboard and click "Update" in Finder.

If you downloaded an IPSW file, you might be prompted to select it now. Browse your computer and choose the file.

iTunes/Finder will verify and update your iPhone. It might take some time, so be patient and don't disconnect your iPhone.

Once the update is complete, your iPhone will restart automatically.


By following these comprehensive steps and utilizing the appropriate method, you should be able to successfully troubleshoot the problem seeing “software update failed” on the screen and getting your device updated to the latest version.
