I know that spinning circle is mocking you right now. You waited for the update to download, watched the progress bar crawl, and now it's been sitting there for what feels like an eternity. Let's get you out of this.
The Fastest Fix: Force Restart Your iPhone
Most of the time, this is just a software handshake gone wrong during the update. The OS is partially updated, and the boot process is stuck waiting on a process that never finished. A force restart clears that temporary state and lets the phone try again.
- Press and quickly release the Volume Up button.
- Press and quickly release the Volume Down button.
- Press and hold the Side button until you see the Apple logo. Don't let go when the spinner appears—keep holding until the logo shows.
This works on iPhone 8 and newer (including iPhone 15). For iPhone 7 and older, the button combo is different, but if you're running iOS 17, you're likely on a newer device anyway.
After the force restart, give it a solid two minutes. If the spinner comes back and stays, move to the next step.
Why This Works
The force restart isn't a magic trick—it's a hard interrupt. During an iOS update, the system writes new kernel extensions and system apps. If one of those writes gets interrupted by a low-power state or a background process, the boot loader sits waiting for a response that never comes. The force restart kills all running processes and forces a clean boot. It's like yanking the power cord on a desktop PC that froze—same concept.
When the Spinner Persists: Recovery Mode
If the force restart didn't do it, the update is corrupted. This happens more than you'd think, usually because the update was installed over a nearly full storage drive (less than 1GB free) or the Wi-Fi dropped mid-download but the phone tried to install anyway.
Step 1: Put Your iPhone in Recovery Mode
- Connect your iPhone to a computer with the latest version of Finder (macOS Catalina or later) or iTunes (Windows or older macOS).
- Press and release Volume Up, then Volume Down, then press and hold the Side button. Keep holding even when the Apple logo appears.
- After about 10-15 seconds, you'll see a screen with a computer icon and a cable. That's recovery mode.
Step 2: Update or Restore
On your computer, a dialog should pop up saying your iPhone has a problem and needs to be updated or restored.
- Update: This tries to reinstall iOS without wiping your data. Try this first. It takes longer but keeps your photos and messages.
- Restore: This wipes everything and installs a fresh copy. Only do this if Update fails.
In my experience, Update works about 60% of the time when the spinner appears. If it fails, you're not out of luck—it just means the recovery partition itself was damaged, and you need a full restore.
Less Common Variations
Sometimes the spinner shows up in a different context, and the fix changes.
Spinner After Entering Passcode
This one usually happens when the update didn't fully finalize. You force restart, the phone boots to the lock screen, you type your passcode, and it spins again. The fix here is the same recovery mode update, but you might also want to make sure you have enough storage. Check by going to Settings > General > iPhone Storage once you're back in. If you're under 1GB free, that's your problem. Delete some large videos or offload unused apps before the next update.
Spinner with a Progress Bar Underneath
This is actually normal during an update install phase. If it sits for more than 30 minutes, though, something's stuck. Disconnect from any Bluetooth devices—I've seen a bug with AirPods that interrupts the update handshake. Then force restart.
Spinner After Restore from iTunes
If you just restored from a backup and it's spinning, it's likely a corrupt backup. This is rare, but when it happens, you're better off restoring as a new phone and then syncing only your important stuff—contacts, photos, notes—via iCloud or a third-party tool.
Prevention: Don't Let This Happen Again
You can't avoid every stuck update, but you can stack the odds in your favor.
- Free up at least 2GB of storage before any major iOS update. Go to Settings > General > iPhone Storage and see what's eating space. Offload unused apps.
- Connect to a stable Wi-Fi network and keep the phone plugged into power. A low battery during an update is a common cause of corruption.
- Update via Finder/iTunes if you've had issues before. Wired updates are more reliable because they don't rely on a wireless connection.
- Back up before updating—ideally to iCloud and your computer. If something goes wrong, you'll thank yourself later.
One more thing: if your iPhone is older than an iPhone X and you're updating to iOS 17, it shouldn't be supported anyway. But if you're using a workaround or a beta, that's a whole other mess, and honestly, I'd skip the betas on your daily driver.
That spinning circle is a pain, but it's rarely permanent. Try the force restart first, then recovery mode. You've got this.
