iOS software updates provide important new features and security updates for iPhones. But occasionally, errors can occur during the update process. One common error is the “Error 6” message that some users encounter when trying to install an iOS update.
The Error 6 message typically appears during an over-the-air software update or when using iTunes to install the latest iOS version. It indicates a problem communicating with Apple’s update servers. This error is often temporary, but can sometimes require troubleshooting to fix.
This article provides an overview of the Error 6 message – what it means, what causes it, how to fix it, and when to seek further support. With some guided troubleshooting steps, most users are able to resolve the Error 6 message and continue updating their iPhones.
What Does the Error 6 Message Mean?
The error 6 message on iPhone indicates that an iOS software update has failed due to an unidentified issue.
Specifically, error 6 signifies that the iPhone could not complete installing or downloading the iOS update. It is a general error code that Apple uses when the exact cause of the update failure cannot be determined.
When error 6 appears, the update process is abruptly halted. The error message will typically say something like “Unable to Install Update. An unknown error occurred (6).”
Error 6 does not provide any details about what went wrong. It simply means the iPhone update did not complete successfully for some reason. The underlying problem could stem from issues like a poor internet connection, not enough storage space, or a corrupt download of the software update itself.
In summary, the error 6 message represents a failed iOS update of an ambiguous cause that prevents the iPhone from properly installing the latest software version (“Update Error6” – Apple Community). Troubleshooting steps are required to resolve the error and complete the interrupted update.
Common Causes of the Error 6 Message
There are a few common causes behind the error 6 message that users may encounter when trying to update their iPhone:
Insufficient storage space – The iPhone requires a certain amount of available storage space to successfully install an iOS update. If your iPhone is low on storage, it may fail to update and show the error 6 message. Trying to delete apps, photos, or other data to free up storage space may help resolve the issue.
Interrupted update process – If the iPhone loses connection to the internet or power during an iOS update, it can get interrupted halfway and fail with error 6. Restarting the update with a stable WiFi connection often fixes this problem.
Network issues – Weak WiFi signals, using mobile data, VPNs, firewalls, or proxy connections can also disrupt the iPhone update process and lead to error 6. Trying the update again with a stronger WiFi network should help overcome network-related problems.
Corrupt update files – In rare cases, the iOS update files themselves may be corrupted or damaged, resulting in the update failing with error 6. Deleting the iOS update and redownloading it through iTunes can eliminate any problems with corrupt update files.
Outdated version of iTunes – Having an old version of iTunes that is not compatible with the latest iOS can also prevent successful updates and cause error 6. Updating iTunes to the newest version before trying the iOS update again is recommended.

How to Fix the Error 6 Message
There are several steps you can try to fix the error 6 message when updating your iPhone:
First, try clearing up storage space on your device. The update may fail if you don’t have enough free storage available. Go to Settings > General > Storage & iCloud Usage and delete unused apps, messages, photos, or videos to free up space. You need at least 500 MB free, preferably 1-2 GB, for an iOS update to complete successfully.
Next, update your iPhone using iTunes on your computer instead of over-the-air. Connect your iPhone to your computer, open iTunes, select your device, then click Check for Update. This method is more reliable than updating wirelessly.1
You can also try resetting your network settings which will clear any issues with your cellular or WiFi connections that may be preventing the update. Go to Settings > General > Reset > Reset Network Settings. This resets all network adapters, WiFi passwords, and APN settings, so you’ll need to reconnect to your wireless networks afterwards.
For other fixes, see Apple’s support page on iOS update errors2 which provides steps based on your specific error number.
Preventing the Error 6 Message
There are a few key steps you can take to prevent the Error 6 message from appearing when trying to update your iPhone:
- Ensure you have enough storage space – The update process requires several gigabytes of available storage, so make sure you have at least 5GB free before attempting an update. You can check your available storage in Settings > General > iPhone Storage.
- Connect to a stable internet connection – Use a reliable WiFi network or strong cellular connection when downloading and installing an update. Slow or unstable connections are more prone to errors.
- Restart your iPhone before updating – Power your iPhone off completely and then back on. This clears any minor software glitches that could interfere with updating.
Following these preventative measures helps avoid the Error 6 message by ensuring your iPhone has the necessary storage, connectivity, and stability to complete the entire update process without issues. Restarting your device before updating is an especially useful tip, as it often resolves many minor bugs that may trip up an update.

An Apple Support advisor may run diagnostics, suggest additional troubleshooting steps, or set up a repair or replacement if needed. If the error 6 issue points to a hardware malfunction or bug in the latest iOS version, Apple Support can facilitate the best solution based on your specific case.
Contacting Apple Support directly after exhausting self-help steps is recommended, as they can properly investigate what is causing the persisting error 6 messages. Their specialized support can resolve problems that standard troubleshooting cannot fix.
Seeking a Professional Repair
If you have tried all of the software troubleshooting steps and the error 6 message persists, it may indicate an underlying hardware issue with your iPhone. In these cases, seeking professional repair may be necessary to fully resolve the problem.
Hardware issues that could cause the error 6 message include faults with the logic board, problems with connectors/cables, issues with the baseband chip, and defects with Touch ID components [1]. A technician can run diagnostic tests, inspect internal components, and determine if any physical repairs or replacements are needed.
Seeking professional iPhone repair from an Apple Authorized Service Provider or Apple Store is recommended over generic repair shops. Authorized technicians have the training, parts, and tools required for complex iPhone repairs related to the error 6 issue. Using unauthorized services also risks invalidating any warranty.
Before taking your iPhone for professional service, be sure to backup your data, remove any personal/sensitive information, and disable Find My iPhone. Repairs for error 6 typically range from $50-150+ depending on the specific issue and parts needing replacement.
Data Backup Before Updates
It’s highly recommended to backup your iPhone data before installing any iOS updates to avoid potential data loss. According to this article, backing up your iPhone before upgrading ensures that all your photos, messages, settings and other important data is safely stored and can be restored if anything goes wrong during the update process. As noted in this Apple discussion thread, even though most iOS updates install smoothly, backing up provides an extra layer of protection in case errors or issues occur.
The best way to backup an iPhone is using iCloud or iTunes. Apple’s official iOS backup guide here provides step-by-step instructions for enabling iCloud backups to automatically save your data daily when connected to power and WiFi. For extra redundancy, it’s also a good idea to occasionally do manual backups to your computer through iTunes. Taking the time to properly backup your iPhone before any major software update can potentially save you from catastrophic data loss should anything go wrong.
Summary
The iPhone error 6 message typically indicates an issue occurred while attempting to update iOS or install an app. This error is often caused by a poor internet connection, low storage space, or software bugs in the update itself.
To resolve error 6, first try basic troubleshooting like restarting your device, ensuring you have enough storage, and updating over a strong WiFi connection. You can also try deleting and re-downloading the update, or installing it through iTunes on a computer if available.
If these steps don’t work, the update file itself may be corrupt – wait for Apple to release a fixed version. As a last resort, you may need to perform a factory reset or contact Apple Support for further assistance if the error persists.
To avoid error 6 in the future, maintain at least 1GB of available storage, connect to reliable WiFi for updates, and backup your data in case issues arise. With proper care and troubleshooting, you can usually resolve the error 6 message and continue enjoying your iPhone.
