Your iPhone 17 is stuck on the Apple logo. You see the logo, sometimes with a progress bar that doesn't move, sometimes without one. The phone won't boot all the way to the home screen.
This is most often a failed or interrupted iOS update, but it can also be caused by low battery, a corrupted system file, or rarely a hardware issue. Here's the order to work through, from safest to most disruptive.
Force Restart First
Always start here. A force restart is non-destructive and clears the most common cause: a temporary software hang during boot.
Quickly press and release the Volume Up button. Then quickly press and release the Volume Down button. Then press and hold the Side button until you see the Apple logo appear again, which usually takes about 10 seconds.
If the phone boots normally after the force restart, you're done. If it boots and gets stuck again at the same point, move to the next step.
Plug Into a Wall Charger
A surprisingly common cause of an iPhone stuck on the Apple logo is low battery during boot. The phone has enough charge to start the boot process but not enough to complete it, so it hangs.
Plug the iPhone into an official Apple charger and a wall outlet, not a USB hub or a laptop port. Leave it for at least 30 minutes, even if the screen stays on the Apple logo the whole time.
After 30 minutes, force-restart again. Many users report this combination resolves the loop, especially if the issue started after the phone went completely dead overnight.
Remove the SIM Card
Occasionally a SIM-related bug can trigger a boot loop, especially after an iOS update changed how the modem handshakes with your carrier.
Use the SIM tool that came with your iPhone (or a paper clip) to eject the SIM tray. Remove the physical SIM card if you have one, then force-restart the phone with the tray empty.
If the phone boots successfully without the SIM, the issue is SIM-related. Once you're at the home screen, reinsert the SIM card and the phone should recognize it. If it doesn't, contact your carrier for a fresh SIM.
Try Recovery Assistant (New in iOS 26)
iOS 26 introduced Recovery Assistant, a built-in tool that can repair a stuck iPhone without a computer. If the iPhone has been hung on the Apple logo for a few minutes, Recovery Assistant may appear on the screen automatically, offering to diagnose the boot issue and reinstall iOS directly on the device.
If the prompt appears, follow it. The on-device flow handles the heavy lifting and is significantly less involved than the Recovery Mode procedure with a computer.
If Recovery Assistant doesn't appear on its own and the force-restart steps above haven't worked, move on to Recovery Mode with a computer.
Use Recovery Mode
The next path is the classic Recovery Mode with a computer. This is more involved but doesn't necessarily erase your data.
Connect the iPhone to a computer via USB-C cable. If you're on a Mac running macOS Catalina or later, open Finder. If you're on a Windows PC or older Mac, open iTunes (or the Apple Devices app on Windows 11).
While the iPhone is connected, force-restart it again. Continue holding the Side button after the Apple logo appears, until you see the Recovery Mode screen (a cable pointing at a laptop icon).
The computer will detect the iPhone and offer two options: Update or Restore. Choose Update first. Update reinstalls iOS without erasing your data, and this fixes the boot loop in most cases caused by a failed update.
If Update fails or doesn't help, your next option is Restore, which does erase the phone but installs a fresh copy of iOS. Restore from your most recent iCloud or computer backup once it completes.
If the Update Times Out
Recovery Mode has a roughly 15-minute window. If the iOS download takes longer than that and the iPhone leaves Recovery Mode before the update finishes, you have to start over.
The download often continues in the background on the computer even after the iPhone drops out of Recovery Mode. Let it finish, then put the iPhone back into Recovery Mode and try Update again. A faster internet connection helps, and a wired ethernet connection on the computer speeds up the initial download more than people expect.
If Nothing Works
If neither Recovery Assistant nor Recovery Mode brings the phone back, you're looking at a potential hardware issue. The most common is a damaged motherboard component, often related to recent water exposure or physical damage.
Contact Apple Support or schedule a Genius Bar appointment. iPhone 17 units under warranty get diagnostic and repair service free.
If you bought the iPhone in the last 14 days from Apple directly, you can also opt for a return-and-replace rather than a repair, which is usually faster.
