How to fix iphone keeps restarting every a few minutes after update

Using DFU (Device Firmware Update) mode is one of the most effective and completely free methods to fix iPhone boot loop issues, especially when your iPhone keeps restarting every few minutes after an update.

Think of DFU mode as the "nuclear option" for solving iOS problems. Unlike the standard Recovery Mode you might be familiar with, DFU mode works at a much deeper, hardware level . When you fix iPhone boot loop using DFU mode, you are essentially bypassing the current, corrupted operating system entirely and reinstalling a fresh, clean version directly onto the device's firmware . This makes it incredibly powerful for resolving the most stubborn issues, including the continuous restarting you're experiencing.

How to enter DFU mode (iPhone 8 and later):

1. Connect your iPhone to your computer

2. Quickly press and release Volume Up

3. Quickly press and release Volume Down

4. Press and hold the Side button for 5 seconds

5. Without releasing the Side button, also press and hold the Volume Down button for 5 more seconds

6. Release the Side button but continue holding Volume Down for another 10 seconds
