How to Fix an iPhone Stuck on Preparing iOS 18/26 Update

Part 1: Why is my iPhone Stuck on Preparing iOS 18/26 Update?

If your iPhone is stuck on the “Preparing Update” screen while installing iOS 18 or iOS 26, don’t panic—this is a common issue faced by many users during major iOS rollouts. Whether it’s due to network instability, software glitches, or storage limitations, these delays can disrupt the update process and prevent you from accessing the latest iOS features.

There may be various reasons causing your iPhone to get stuck on preparing the iOS 18/26 update. Let's see what some common causes are:

• Slow or unstable internet connection: A poor internet connection may lead to slow speeds or interruptions during downloading and preparing the iOS update file.
• Insufficient storage space: During an update, your iPhone may get stuck or malfunction if it has low storage space.
• Low battery: Issues with the updating procedure may arise from a low battery level. It is advised by Apple that you update your iPhone when fully charged.
• Corrupted update file: The preparing update screen may become stuck if the iOS 18/26 update file you downloaded is faulty or incomplete.
• Background processes: The preparation process for updates may be affected by background programs and services that require system resources.
• Performance of the device: Compared to newer models, older iPhone models with less RAM and a slower processor may take longer to install updates.

Part 2: Step-by-Step Guide on How to Fix an iPhone Stuck During Update

If you are installing the latest iOS update and find that your iPhone is getting stuck on the Preparing Update screen, worry not. To unstuck and update, there are several methods you can use for fixing. Here's a step-by-step guide on what to do:

Step 1: Make Sure You Have a Stable Internet Connection

When updating iOS, an unstable or poor internet connection could cause the problem. Ensure you have a stable cellular data connection or a strong Wi-Fi network. Switch to a different network or stand close to your wireless router if needed.

Step 2: Check Your Storage Space on iPhone

To update your iOS, ensure your device has enough storage space. Go to Settings > General > iPhone Storage and check the available space. If running low, delete unused apps, photos, or files to free up space. Aim to have at least 5GB of free storage before attempting the update again.

Step 3: Fully Charge Your iPhone

Apple recommends updating whenever your iPhone has 50% battery life. Charge your device by plugging it into power before performing the iOS 18/26 update.

Step 3: Force Restart Your iPhone

A hard reboot helps resolve temporary bugs or issues that may cause your iPhone to freeze during the update process.

• For iPhone 8 or later: Press and release the volume up button, click and release the volume down button, then press the side button and hold until the Apple logo appears.
• For iPhone 7/7 Plus: Press and hold the volume down and the side button simultaneously until the Apple logo appears.
• For iPhone 6s and below: Press and hold the home button. You may press the side or top button until the Apple logo appears.

Step 4: Delete the Existing iOS 18/26 Update File

Sometimes, this issue of an iPhone can be caused by a downloaded file that is corrupted. Delete the existing download file and redownload a fresh copy as follows:

1. Click on Settings, then click General. Now click on iPhone Storage and navigate to the iOS 18/26 update file.
2. Tap on the update file and then click on the Delete Update option.
3. Go to Settings > General > Software Update. Tap Download and Install to get the fresh iOS 18/26.
4. Using iTunes or Finder to Update

If you have tried everything and all else fails, you may update your iPhone to iOS 18/26 using a computer.
