Unboxing a brand-new iPhone should be exciting, but a software update stall can stop Setup Assistant before you even reach the Home Screen. An iPhone 18 Pro stuck on the software update screen can interrupt data transfers, backup restores, and initial setup. In some cases, the new iPhone needs a newer iOS version before it can restore your existing backup.
The update may stall while checking, downloading, preparing, verifying, or installing iOS. Identifying the exact stage helps you choose the right solution instead of restarting everything blindly. This practical guide covers 7 practical fixes, including Dr.Fone - System Repair (iOS) for persistent software-related installation failures.

Part 1. Where Is the iPhone 18 Pro Software Update Actually Stuck?
If your iPhone 18 Pro software update is stuck, identify the exact stage where it stopped first. The table below shows common signs and the appropriate first action:
| Update Stage | What the iPhone Is Doing | What Counts as a Real Problem | First Action |
|---|---|---|---|
| Checking for Update | Contacting Apple's servers | Repeatedly fails to check | Switch Wi-Fi networks |
| Downloading Update | Downloading the iOS package | Progress repeatedly stops | Check connection stability |
| Preparing Update | Preparing update files | Remains stuck unusually long | Delete and redownload |
| Verifying Update | Verifying the update with Apple | Repeated verification failure | Try a different network |
| Install Now Spinning | Waiting to begin installation | Spinner remains unchanged | Force restart, then retry |
| Apple Logo With Progress | Installing the iOS update | Progress remains unchanged unusually long | Wait before interrupting |
| Back at Software Update | Previous attempt did not complete | Same update repeatedly fails | Try Apple's version workaround |
Part 2. Why Does a Brand-New iPhone Need a Software Update During Setup?
An iPhone 18 Pro iOS update taking forever can result from several setup, software, or connection issues. Here are 5 common reasons behind the delay:
- Factory-Installed iOS is Not the Latest: A brand-new iPhone can ship with an iOS version released before the latest update. Setup may therefore offer or require newer software during configuration.
- Backup Requires Newer iOS: An iCloud or computer backup may have been created on a newer iOS release. Apple requires a compatible iOS version before that backup can be restored.
- Device-to-Device Transfer Needs Compatibility: The old and new iPhones may run different software versions. Updating the destination device can provide the compatibility needed to complete migration successfully.
- Quick Start Triggers the Update During Setup: Quick Start checks requirements while configuring and transferring data to the new iPhone. A necessary software update can therefore appear before migration finishes.
- Apple Provides Updates During Activation and Setup: A newer iOS release may already be available when the iPhone is first activated. Installing it during setup brings the new device onto the current available software.
Part 3. 7 Fixes for iPhone 18 Pro Stuck on Software Update During Setup
Based on these causes, follow the 7 solutions below to fix an iPhone 18 Pro stuck on a software update during setup or after completing the initial setup.
Fix 1. Make Sure the iOS Update Is Actually Stuck
A slow iOS update does not necessarily mean the process has stalled. Apple explains that update time can vary based on the download size and internet speed. Keep the new iPhone connected to power and a stable Wi-Fi network. Watch the progress indicator and allow the update more time if it continues moving.
Fix 2. Fix the Wi-Fi or Update-Server Connection
An iPhone 18 Pro update stuck during setup may show “Unable to Check for Update,” “Unable to Download,” or another connection-related error. These messages can appear when the iPhone cannot reach Apple's update servers. Apple recommends retrying the update and switching networks if the problem continues.
Keep the iPhone connected to a stable Wi-Fi network during setup. Retry the update on the same network first. If it still fails, connect the iPhone to another reliable Wi-Fi network and try again.
Fix 3. Force Restart the iPhone and Retry Setup
For persistent iPhone 18 Pro stuck installing iOS issues, a force restart can help interrupt frozen software loops and reload the device's operating code. The process also resets the temporary working memory (RAM) and system code without erasing personal files. Here's how to perform a force restart:
Instructions. Press and quickly release “Volume Up,” then hold and release the “Volume Down” button. Keep holding the “Side” button and release it when the Apple logo appears. Let Setup Assistant restart, then check whether the software update progresses beyond where it previously stopped.
Fix 4. Finish Setup Without Transferring, Update, Then Restart the Migration
If your backup requires a newer iOS version, Apple recommends temporarily setting up the new iPhone without transferring your data. This allows you to update iOS while keeping the existing backup available for restoration afterward. Follow these steps to resolve the iPhone 18 Pro stuck on software update during setup issue using this workaround:
-
Step 1 Select “Don't Transfer Apps & Data”
On the “Transfer Your Apps & Data” screen, select “Don't Transfer Apps & Data.” Complete the temporary setup while skipping the Apple Account, Face ID, and passcode options.
-
Step 2 Update iOS from Settings
Once you reach the home screen, connect to a strong Wi-Fi network. Go to “Settings > General > Software Update > Update Now” and install the latest iOS update directly.
-
Step 3 Erase Only the New iPhone and Restart Setup
After the update finishes, factory reset the phone by going to “Settings > General > Transfer or Reset iPhone > Erase All Content and Settings > Continue.” After the iPhone restarts at the Hello screen, run Setup Assistant again and select the backup you want to restore.
Fix 5. Delete the Downloaded Update and Download a Fresh Copy
For an iPhone 18 Pro stuck installing iOS after setup, deleting the existing update package and downloading a fresh copy may resolve the issue. Delete the existing iOS update from storage, then download a fresh copy before attempting the installation again. Follow these 2 simple steps to complete the process:
-
Step 1 Delete the Existing Update
Open “Settings > General > iPhone Storage,” select the downloaded “iOS Update,” then tap “Delete Update > Delete.”
-
Step 2 Download the Update Again
Head back to “General > Software Update > Update Now” to get a clean, fresh copy of the update. Keep your phone connected to a strong Wi-Fi network and ensure it has enough battery or is plugged in while the new copy downloads.
Fix 6. Update the New iPhone with a Mac or Windows PC
The iPhone 18 Pro software update stuck issue may require a computer-based update if wireless troubleshooting does not work. Apple supports updating through Finder on a Mac or Apple Devices/iTunes on a Windows PC. This provides another way to download and install the available iOS update. Go through these steps to perform this fix without any errors:
-
Step 1 Access Recovery Mode
Turn off the iPhone 18 Pro and wait about one minute. Hold the “Side” button through “Continue Holding for Recovery…” and release it at “Loading Recovery Options….” Select “Recovery Mode > Restart iPhone,” then quickly connect the iPhone to your Mac or Windows PC using a USB cable.
-
Step 2 Choose Update
Open Finder on a Mac or Apple Devices/iTunes on Windows and select the connected iPhone. Choose “Update” to reinstall iOS without erasing your data. Avoid “Restore,” as this option reinstalls iOS and erases the device.
Fix 7. Repair a Genuine iOS Installation Failure with Dr.Fone - System Repair (iOS)
If the “iPhone 18 Pro is stuck on a software update” problem continues, the issue may be tied to the iOS installation itself. Dr.Fone - System Repair (iOS) provides Standard Repair for software-related update failures without erasing personal data.

Part 6. What Should You Protect Before Restarting Setup?
Once the iPhone 18 Pro stuck installing iOS issue is resolved, protect your important data before restarting Setup Assistant. Here are 5 precautions to take first:
- Keep the Old iPhone Intact: Do not erase, reset, or trade in your old iPhone until the transfer finishes. Confirm that all important data reached the new device first.
- Maintain a Recent Backup: Create a fresh iCloud or computer backup of the old iPhone before restarting setup. This provides a recovery copy if the transfer fails.
- Verify Source Data First: Check that important photos, messages, contacts, and files remain accessible on the old iPhone. This ensures your source data is intact before another transfer attempt.
- Erase Only the New iPhone: Apply any required erase-and-restore process only to the new destination iPhone. Avoid erasing the old device while it still holds your original data.
- Avoid Restore Unless Necessary: Recovery Mode Restore reinstalls iOS and erases the iPhone. Try the non-erasing Update option first, and use Restore only when necessary.

To conclude, an iPhone 18 Pro stuck on a software update can often be fixed by identifying the stage causing the problem. Start with network, download, and iOS compatibility fixes before considering system repair. When persistent software-related installation failures prevent setup from completing, Dr.Fone - System Repair (iOS) offers Standard Repair to resolve system issues without erasing data from the new iPhone.
