2. Check network status
Ensure you have a continuous, good-speed internet connection when updating iOS. The success of the iPhone update depends upon the speed of your Internet.
Close all the apps and do not download any other content on your iPhone while the Update is on.
3. Check Apple update servers
Apple update servers facilitate OTA updates for downloading and installing iOS updates for all iPhones and iPads. The servers play an important role in ensuring a bug-free device with the latest features and security patches. However, if the update servers are down, it may also result in the iPhone Software Update Failed error.
You can visit this link—https://www.apple.com/in/support/systemstatus/— to view the status of the Apple update servers. While the green icon indicates everything is fine, a yellow icon indicates a potential error in the server. If there’s an issue in the server, you can simply wait for it to be resolved.
4. Restart your iPhone
Simply restarting or rebooting your iPhone can fix the failed update error.
To restart your iPhone (iPhone 8 and previous models):
- Press and hold the Top (or Side) button until the slider appears.
- Drag the slider to turn off the iPhone.
- Press and hold the Top (or Side) key again until you see the Apple logo.
5. Reset Network Settings on your iPhone
If a restart does not help, the problem could be with your device’s network settings. For example, maybe Wi-Fi is not working, or your iPhone cannot connect to a Wi-Fi network. Reset Network Settings to fix any network-related issue that is preventing the Update from completing. It will thereby fix the ‘iPhone software update failed’ error.
To Reset Network Setting on your iPhone: Go to Settings > General > Reset > Reset Network Settings.
Now turn off your iPhone. Then, after a few seconds again, turn on and retry the iOS update.
Note: The Reset Network Settings option deletes all your Wi-Fi passwords, network preferences, cellular settings, VPN, and APN settings. You can note down your passwords and preferences to add later.
6. Update iPhone via iTunes
Instead of directly downloading the software on your iPhone, update via iTunes on a computer.
Steps to update iPhone via iTunes
- Connect your computer to a Wi-Fi or Ethernet network
- Install the latest version of iTunes on your computer
- Connect your iPhone to the computer
- Open iTunes and select your device
- Click to follow Summary > Check for Update > Download and Update.
- If asked, enter your passcode.
- Update will start automatically.
7. Delete iOS beta version
iOS beta version is a soft pre-release of an Apple iOS update, such as iOS18, that gets silently downloaded to our devices. These are kind of privy software updates that happen in the background if you have agreed to be a part of the beta testing program.
These beta updates are distributed among a few interested users even before the release. It helps Apple test the software and collect performance, stability, and other relevant data to fix any bugs or issues before the final release of the updates.
However, this could sometimes hinder the normal update process for many users as the beta version is already there on the devices. Hence, you must delete the iOS beta version for the actual iOS update to start normally.
To remove the iOS beta version of the actual update, you can go to your device Settings and search for Beta Updates. Once you enter the Beta Updates, go to the Profile option and click on the Remove Profile option to delete it.
Otherwise, you can follow this path – Settings > General > Profile > Remove Profile to remove the iOS beta version.
8. Free up storage space in your iPhone
‘iPhone software update failed’ error can also appear if your mobile does not have enough space for the latest iOS files. Free up more storage space by deleting unwanted apps, photos, videos, cache, junk files, etc.
To remove unwanted data, follow Settings > General > Storage & iCloud Usage and tap Manage Storage.
Now, try again to update your iPhone to the latest iOS.
9. Wait for a few hours before retrying
Whenever Apple launches a new iOS update, millions of users worldwide immediately try to connect to its servers for the Update. It naturally builds up huge traffic on Apple’s site, often preventing your device from connecting with the server. Thus, giving the ‘iPhone software update failed’ error. The best way is to wait a few hours before updating your iPhone.
10. Manually update iPhone
You can update your iPhone manually by downloading the IPSW firmware files. IPSW files are firmware downloads for specific Apple devices and iOS/iPadOS versions. You can use these files to update iOS manually via iTunes.
Use this option as a last resort when the above methods fail to fix the ‘iPhone software update failed’ error.
Steps to manually update iOS on your iPhone

On Windows: Hold the SHIFT key and click on Update in iTunes.
On Mac: Hold the OPTION key and click on Update in iTunes. - Browse and select the IPSW file you downloaded on your computer and click Choose.

Does Manual iOS Update Lead to iPhone Data Loss?

Hi once the new 17 update was done on my phone I have had issues since. When texting it will flash to another screen he. Back to the text screen. Most websites I go to won’t download or it takes way to long to do so. How can I fix this?
Hi Tedina,
Thank you for reaching out Stellar.
I understand the issue of getting unwanted notification of “Unable to Check for Updates” on your iPhone and iPad.
You must have already tried the temporary glitches that can overcome this issue. But still if the problem persists, then Check for hidden updates – Sometimes minor updates aren’t displayed as “Software Update” but are still available. Go to Settings > General > About and see if any updates are listed under “Automatic Downloads.” Also, it is recommended to free up storage space. If your device storage is almost full, it might prevent updates from downloading.
Moreover, you can also ‘Check Apple’s system‘ status page to see if there are any issues with the Software Update service.
I hope it works for you.
My iphone 12 wont update to the newest IOS, every time i get the error ‘its not connected to the internet’. Its weird, i used multiple Wi-Fi connections to try it, i can use Google, everything works with that. So i’ve tried to delete the update, doestn work. Ive erased all network settings, ive erased all settings, even went back to factory settings, it wont work.

Hi Leroy,
We can understand your frustration. You can try updating it using iTunes or Finder on your computer. To do this, connect your iPhone to your computer and open iTunes or Finder.

Hey I am trying to update my I pro 14 max but I can find were to do that can you please help
Hi Elizabeth,
Thanks for reaching out.
The most likely solution for you is to try the first step, which is to check for iOS updates. If the your iPhone is not running the latest version of iOS, it may not be able to update to the latest version. You can check for updates by going to Settings > General > Software Update. If there is an update available, you can tap on Download and Install to install the update.
If your iPhone is already running the latest version of iOS, you can try the other steps in the blog post, such as restarting your iPhone or checking the network settings. If you have tried all of the steps in the blog post and still unable to update the iPhone, you may need to contact Apple support for help.
I hope it helps!
