[2026] How to Update iPhone on Computer Without iTunes?

You can update iPhone without iTunes in several modern ways. In 2026, the main options are Settings on the iPhone, Finder on Mac, the Apple Devices app on Windows, or a guided repair/update tool when an iOS 27 update will not finish.

This guide explains how to update iPhone on computer without iTunes, when an IPSW file makes sense, and what to try when the iOS 27 update gets stuck during download, preparing, verifying, or installation.

Quick answer

To update iPhone without iTunes, use Settings > General > Software Update first. If you need to know how to update iPhone from computer or how to update iPhone on computer without iTunes, use Finder on Mac, Apple Devices on Windows, or iMyFone Fixppo when the update process is stuck. Back up before using computer update, repair, IPSW, or restore paths.

If the iPhone cannot complete iOS 27 from Settings, a computer update is the next step. Mac users should use Finder, Windows users can use the Apple Devices app where available, and older setups may still use iTunes.

iMyFone Fixppo is a strong fit when the normal update path is already failing. It gives a guided firmware workflow with iOS Upgrade/Downgrade, Standard Mode repair, recovery mode tools, and built-in backup/restore for people who do not want to handle IPSW files manually.

Over-the-air update is still the cleanest way to update iOS without iTunes. Use it when the iPhone works normally, Wi-Fi is stable, battery is above 50 percent or charging, and there is enough free storage for iOS 27.

If Software Update stays on Update Requested, Preparing Update, or Verifying Update for a long time, delete the update file if it appears in iPhone Storage, restart, and retry on stable Wi-Fi before moving to a computer.

Step 1: Open the Settings app, click on General > Software Update.

Step 2: Wait for iPhone to check for the iOS update, then click Download and Install > Update Now to make an update.

Step 3: Wait patiently for the update to complete. It's suggested not to use the device during the process.

An IPSW file is useful only when the firmware is signed for your exact iPhone model. Downloading the wrong or unsigned file wastes time and may push you into restore instead of update.

For iOS 27, use IPSW carefully: back up first, choose Update rather than Restore when possible, and remember that this method still normally requires Finder, Apple Devices, or iTunes to apply the file.

Step 2: Find the signed IPSW file then download it to your computer.

Step 3: Launch iTunes on your computer and connect your device to it.

Step 4: When iTunes recognize your device, press the Option key for Mac users or Shift key for Windows users, then click the Check for Update at the same time.

Step 5: From the window, choose the IPSW file you just downloaded and open it. Later, wait for iTunes to use the downloaded IPSW file to update your iPhone's system.
