Once my iPhone was stuck in a boot loop, which gave me a headache. I tried to force it into recovery mode. I turned off my phone, then held down the power button and volume down button. After about ten seconds, an icon for connecting to iTunes appeared on the screen.

At this time, I quickly plugged my phone into the computer, opened iTunes, and finally recognized the device! The next step was to choose to restore the system. Although the entire recovery process took a long time, the iPhone finally restarted and the problem was solved. If you also encounter this kind of boot loop problem, you might as well try this method, which is quite effective.

iPhone is stuck in a boot loop? Sometimes a force restart can help fix common issues. The process for force restarting differs based on the iPhone model:

• iPhone 8 or later: Quickly press and release the Volume Up button, then the Volume Down button, and then press and hold the Side button until you see the Apple logo.
• iPhone 7/7 Plus: Press and hold both the Volume Down and the Side buttons until you see the Apple logo.
• iPhone 6s or earlier: Press and hold both the Home and the Top (or Side) buttons until you see the Apple logo.

Haha, try changing the data cable. Don't underestimate the problem of the data cable! When my iPhone was stuck in boot loop won't restore, I couldn't connect to iTunes. Later, I changed the data cable and found that the original cable might have poor contact or was broken. After changing the new cable, iTunes could recognize the phone immediately. I suggest you try this simplest method. It may be such a simple problem that you are stuck!

If your iPhone is stuck in boot loop won't restore, it's also a good idea to try to completely drain the battery and shut down the phone. When I've encountered similar situations before, I let the battery drain completely and waited until the phone automatically shut down. Then, I plugged in the charger and waited for it to charge a little before trying to turn it on. Surprisingly, this method actually worked and the phone successfully jumped out of the loop! Sometimes the battery status can affect the boot problem, so I suggest you try this.

When your iPhone is stuck in boot loop, and it still won’t boot up, try putting it into Recovery Mode:

1. Connect your iPhone to your computer and open iTunes (or Finder if on a Mac).
2. Perform a force restart as described above, but this time, keep holding the button(s) until you see the Recovery Mode screen (usually shows a cable and an iTunes icon).
3. Once in Recovery Mode, iTunes should prompt you to either update or restore your iPhone. Choose Restore.

DanielRomero I have done it with my iPhone by reinstalling the iOS firmware. Before doing this, make sure you have a backup of iPhone.

DanielRomero  An iPhone can get stuck in a boot loop for several reasons, including:

Software Issues: Corrupted software updates, failed installations, or incompatible apps can cause the device to malfunction during boot.

Hardware Problems: Issues with internal components, such as a failing battery or logic board, may prevent the iPhone from starting up correctly.

Jailbreaking: Modifying the device's software can lead to instability and boot loops, especially if something goes wrong during the process.

Overheating: Excessive heat can lead to temporary malfunctions that might cause a boot loop.

You have to first know the root reason and then try recommended way to fix iPhone stuck in boot loop and won't restore issue.

If Recovery Mode doesn't work, you can try DFU to fix iPhone stuck in boot loop:

1. Connect your iPhone to your PC.
2. Open iTunes or Finder.
3. For iPhone 8 and later: Quickly press and release Volume Up, then Volume Down. Then press and hold the Side button until the screen goes black. While holding the Side button, hold down the Volume Down button for about 5 seconds, then release the Side button while continuing to hold the Volume Down button for another 10 seconds. The screen should remain black.
4. For iPhone 7/7 Plus: Press and hold both the Side (or Top) button and Volume Down for 8 seconds. After 8 seconds, release the Side button while continuing to hold the Volume Down button for about 5 seconds. The screen should remain black.
5. For iPhone 6s and earlier: Press and hold both the Home and the Top (or Side) buttons for 8 seconds. After 8 seconds, release the Top (or Side) button while continuing to hold the Home button for about 5 seconds. The screen should remain black.

iTunes/Finder should recognize that a device is connected in recovery mode.

When your iPhone is stuck in a boot loop, sometimes a forced restart alone won't help. If you've tried these methods and they didn't work, here are some more things you can try:

1. DFU mode: A little more powerful than recovery mode, entering DFU mode (Device Firmware Update mode) allows iTunes to completely reinstall the system. It's done in much the same way as recovery mode, except the screen will remain black and you'll restore the system using iTunes.
2. Remove your SIM card: Sometimes a SIM card can cause a boot loop, especially if a carrier-related update fails. Try removing your SIM card and restarting your phone to see if you can boot it back up.
3. Check the charging port: If you're experiencing a poor connection on your phone or dust in the charging port that's causing unstable current, this can also cause a boot loop. Clean the charging port or try using a different charging cable.
4. Boot in safe mode: While the iPhone doesn't have a traditional safe mode like Android does, sometimes you can try holding down the volume button while booting to see if you can disable some startup items that might be caused by an app.
