PART 2 How to fix an issue where I can't update to iOS 17

1. Check the network status of the iOS device

A stable Internet connection is a prerequisite for a successful upgrade to iOS 17. If the iOS 14 update fails, you can quickly check your device's network connection status and its speed to troubleshoot the update failure due to a network failure. When upgrading your iPhone to the latest iOS 17, we recommend that you close all apps to avoid downloading other tasks at the same time.

2. Reset network Settings

In addition, if your device is connected to Wi-Fi that is not working properly, you can also reset the network Settings to resolve the issue of iPhone iOS 14 update failure. The detailed steps are as follows.

Step 1 Turn on your iPhone, go to Settings and go to General Options.

Step 2 Click on the Reset function and select Reset network Settings.

Step 3 Turn off the iPhone and wait a few seconds before restarting the device and trying the iOS update again.

Note: After resetting your network Settings, all Wi-Fi passwords, network preferences, cellular Settings, and APN and VPN Settings on your iPhone will be deleted.

3. Create storage space

If you can't update iOS 14 to iOS 17 after trying to fix the network issues above, you also need to check if your iOS device has enough space to store the latest iOS files. If the upgrade fails due to insufficient storage space, you can create sufficient storage space by deleting unnecessary junk files, cache, photos, applications, and videos. The specific operation is as follows.

Step 1 Turn on your iPhone, go to Settings and go to General Options.

Step 2 Click on Storage and iCloud Usage options and select Manage Storage.

Step 3 After deleting unwanted junk files, caches, photos, apps, and videos, try updating again.
