[9 Proven Ways] How to Fix iPhone Stuck in Boot Loop 2026

There are many reasons why your iPhone/iPad stuck in reboot loop on iOS 27. Before trying the solutions, let’s first explore the possible causes of this issue.

• Failed iOS Software Update: An interrupted or corrupt iOS 27 update can cause the iPhone turns on and off loop.
• Jailbreaking Errors: Improper jailbreaking may affect system stability and trigger iPhone boot loop.
• Corrupt Apps or Files: Buggy apps or damaged files can lead to the boot loop cycle.

• Battery Problems: An improperly connected battery might cause iPhone in boot loop issue.
• Damaged Components: Internal hardware damage like water damage, may result in an iPhone boot loop.

• Low Storage Space: Your iPhone may stuck in boot loop or shut down due to full storage.
• Unstable Connection: A disrupted network during an Finder / Apple Devices / iTunes update may result in a boot loop.

Losing important data can be frustrating, especially when fixing issues like an iPhone boot loop. To prevent this, it's crucial to back up your iPhone before attempting any iPhone boot loop fix. Here are the best ways to keep your data safe.

1 How to Back Up Using iCloud?

If you prefer a wireless backup solution, iCloud is the easiest way to protect your data. With just a few taps, you can securely store your iPhone data in the cloud and restore it whenever needed. Here’s how to back up your iPhone using iCloud:

Step 1: Connect your iPhone to a Wi-Fi network.

Step 2: Go to Settings > [Your Name] > iCloud > iCloud Backup.

Step 3: Tap Back Up This iPhone > Back Up Now and wait for the process to complete.

2 How to Back Up Using Finder / Apple Devices / iTunes?

If your iPhone doesn't have enough iCloud storage, you can use Finder / Apple Devices / iTunes or Finder to back up your iPhone to a computer. This method ensures you have a full backup stored safely on your PC or Mac. Follow these steps to back up your iPhone using Finder / Apple Devices / iTunes or Finder before fixing iPhone restart loop:

Step 1: Open Finder / Apple Devices / iTunes (for Windows or macOS Mojave) or Finder (for macOS Catalina and later).

Step 2: Connect your iPhone to the computer via USB cable.

Step 3: Click the device icon, then select Back Up Now shown on the right side.

iPhone reboot loop is an annoying issue that can affect any model. To regain full access, you need to fix it quickly. To solve the problem with guided repair flow, an iPhone boot loop repair tool is a great option, or you can start with some basic troubleshooting methods.

1 Check iPhone Battery & Charging Status

Check charging first. A weak battery, damaged cable, dirty port, or unstable power source can make an iPhone restart before iOS finishes loading. Charge for at least 30 minutes, try a known-good cable and adapter, then test again before moving to firmware repair.

2 Force Restart iPhone to Fix iPhone Reboot Loop

Force restart is the fastest first step for an iPhone reboot loop because it interrupts a failed startup cycle without erasing the device. If the loop returns immediately after the Apple logo, treat it as a deeper iOS or firmware issue.

To force restart iPhone 8/X/11/12/13/14/15/16/17: Quickly press and release the Volume Up button. Then, quickly press and release the Volume Down button. Finally, press and hold the Power button until you see the Apple logo.

To force restart iPhone 7/7 Plus: Press and hold the Volume Down + Power buttons for about 10 seconds, don't release them until the Apple logo appears.

To force restart iPhone 6/6s and earlier: Press the Home + Power buttons. When you see the Apple logo, release the buttons.

Tips

If you fail to restart your iPhone manually after several attempts or one of your iPhone buttons is broken, you can try to restart iPhone from computer, which requires a few seconds only.

3 Reset All Settings to Fix iPhone Stuck on Boot Up Screen

If your iPhone is stuck in a boot loop, resetting all settings can help fix the issue without erasing your personal data. This process only restores system preferences like Wi-Fi and Bluetooth to default, potentially resolving any glitches causing the boot loop.

If you can access the iPhone's settings occasionally, follow these steps to reset all settings on your iPhone:

Step 1: Go to iPhone Settings > General.

Step 2: Scroll down to find Transfer or Reset iPhone > Reset.

Step 3: Click Reset All Settings, enter your screen passcode to confirm the action and proceed.

If the recovery mode doesn't work for you, putting the iPhone in DFU (Device Firmware Update) mode can help resolve the iPhone stuck in boot loop issue by restoring the device to its factory settings.

• Once the screen turns black, press and hold both the Volume Down + Side buttons for 5 seconds.
• Release the Side button but keep holding the Volume Down button for about 10 more seconds.

• Press and hold the Volume Down + Side buttons at the same time for 10 seconds.
• Release the Side button, but keep holding the Volume Down button for another 5 seconds.
• If your screen stays black and Finder / Apple Devices / iTunes or Finder detects the device in DFU mode, you’ve successfully entered DFU mode.

To avoid iPhone keeps restarting and minimize the chances of encountering boot loop issues again, here're several tips you can follow to make preventions.

Can an iOS 27 update cause an iPhone boot loop?

Yes. An interrupted update, low storage, firmware download problem, or failed restore can leave the iPhone restarting before iOS loads. That does not prove iOS 27 itself is broken; it means the install path needs troubleshooting.

Should I use recovery mode or DFU mode first?

Use recovery mode first because it is easier to exit and may offer an Update option. DFU restore is a deeper erase-based route for serious firmware failure.

When is it hardware instead of software?

If the iPhone restarts only while charging, gets hot, shows battery swelling, has water damage, or still loops after restore, treat it as a hardware problem.

An iPhone boot loop after iOS 27 needs a clear order: charge, force restart, back up if possible, repair the system, then use Apple restore or DFU only when needed. If software methods fail or the device shows damage, stop troubleshooting and get hardware service.

If you want a quick and safe solution, professional iOS system repair software like iMyFone Fixppo is what you need. It helps fix the boot loop iPhone without causing data loss, saving you time and effort. Download it now and give it a try!
