- from Apple Community
When you're ready to install a new iOS update on your iPhone, you'll typically see the "Preparing Update" prompt. Normally, this process takes just a few minutes, but some users have found their iPhone stuck on the preparing update screen, with the progress bar barely moving, sometimes waiting for tens of minutes or even longer.
If you're also encountering the issue of the iPhone being stuck on preparing update, don't worry. This article will explain why your iPhone stuck on preparing update and provide 8 effective solutions to help you quickly resume the update process.

Before installing a new iOS version, your iPhone goes through a phase called "Preparing Update". During this process, the system performs several background tasks to ensure the update is installed correctly and safely. For example, iOS verifies the downloaded update files, unzips the installation package, checks device compatibility, and prepares the system environment for the new update. These steps are crucial for preventing installation failures or system errors.
Normally, this process only takes a few minutes to a dozen minutes. If the time significantly exceeds this range, such as waiting for 30 minutes or longer, it's likely that the update has become stuck, and action needs to be taken to resolve the issue.
Before troubleshooting, understanding the common causes of an iPhone stuck on preparing update can help us address the issue more effectively. Common causes include:
1. Unstable Wi-Fi Network
The update process requires a stable network connection. If the Wi-Fi signal is weak or frequently disconnects, the system may fail to complete the verification process.
2. Insufficient iPhone Storage
iOS updates usually require several GBs of available space. If the device has insufficient space, the preparation process for the update may get stuck.
3. Corrupted Update Files
The downloaded update file may be incomplete or corrupted, preventing the system from continuing the installation.
4. Apple Server Issues
If many users are updating iOS at the same time, Apple's servers may become temporarily overloaded, causing the verification process to slow down.
5. Temporary System Failures
System caches or temporary errors on the iPhone may also cause the update process to stall.
When your iPhone is stuck on preparing update iOS 26, here are some simple and effective solutions. It is recommended to try them one by one in order.
A stable internet connection is essential for completing an iOS update. If your Wi-Fi network is weak, slow, or unstable, the update verification process may stop midway and cause your iPhone to be stuck on preparing update.
Before trying more complicated solutions, it is recommended to check your Wi-Fi connection and ensure your iPhone is connected to a reliable network.
Steps to check your Wi-Fi connection
Step 1. Open "Settings" on your iPhone and then tap "Wi-Fi".
Step 2. Make sure your device is connected to a stable network.
Step 3. Tap the connected Wi-Fi network and choose "Forget This Network".
Step 4. Reconnect to the Wi-Fi network.

Temporary system glitches can sometimes cause the iPhone update process to freeze. If your iPhone is stuck on preparing update iOS 26, performing a force restart can refresh the system and clear temporary errors.
Force restarting does not delete any data and is one of the quickest ways to resolve minor iOS problems.
Steps to force restart iPhone:
For iPhone 8 or later:
For iPhone 7 / 7 Plus:
For iPhone 6s and earlier:

After restarting the device, try updating your iPhone again.
If the downloaded update file becomes corrupted or incomplete, your iPhone may fail to verify it and get stuck on preparing update. In this situation, deleting the update file and downloading it again can solve the problem.
Here are the steps:
Step 1. Go to "Settings" > "General" > "iPhone Storage" and find the iOS update file. (iPhone storage not loading?)
Step 2. Tap the update file and select "Delete Update".

Step 3. Return to "Settings" > "General" > "Software Update", then download and install the update again. (iPhone stuck on software update?)
iOS updates require enough storage space to unpack and install the system files. If your iPhone storage is almost full, the update preparation process may stop and result in the iPhone being stuck on preparing update problem. Therefore, clearing unnecessary files or apps can help the update process continue smoothly.
Steps to free up iPhone storage space:
Step 1. Go to "Settings" > "General" > "iPhone Storage" and check the available space.

Step 2. Delete unused apps, large files, or unnecessary photos and messages to free up storage.
Step 3. Ensure at least 5 GB of free space, then try installing the update again.
Incorrect network configurations or cached network data may interrupt the update verification process. Resetting the network settings can restore all network configurations to their default state and help fix the iPhone stuck on preparing update issue.
Note: Keep in mind that this action will remove saved Wi-Fi passwords and network settings.
Step 1. Go to "Settings" > "General" > "Transfer or Reset iPhone".
Step 2. Select "Reset Network Settings" and enter your passcode to confirm.

Sometimes the issue is not caused by your device but by Apple's servers. When Apple releases a new iOS version, millions of users attempt to update simultaneously, which may temporarily slow down the update verification process. Checking the Apple System Status page can help you confirm whether the update service is working properly.
Steps to check Apple servers:
Step 1. Open a browser and visit the Apple System Status webpage.
Step 2. Look for "iOS Software Update" and check if the status indicator is green. If not, wait and try again later.

If the over-the-air update continues to fail, you can update your iPhone using a computer. Updating through iTunes or Finder can bypass some network or cache issues that cause the iPhone to be stuck on preparing update problem.
Here is how to do it:
Step 1. Connect your iPhone to a computer using a USB cable and open iTunes (Windows or older macOS) or Finder (macOS Catalina or later).
Step 2. Select your iPhone from the device list and click "Check for Update".

Step 3. Choose "Download and Update", then follow the on-screen instructions.
