Why Did the iPhone Boot Loop Bug Occur?

There are many reasons as to why you are encountering the iPhone boot loop right now.

The following are just some of those reasons:

Software Update. When you update your phone and for some reason, it got interrupted, it’s most likely that there will be many errors that would come from it. One such error is the iPhone boot loop. The interruption can happen due to loss of internet connection, sudden power off, and more.
Jailbreaking is without a doubt one of the most dangerous things you can do with your iPhone. If it’s not done properly, it can cause several issues, which may break down your iPhone’s OS.
Charger Malfunction. Just like any other electronic accessories, your charger can sometimes malfunction. This can lead to your iPhone battery not getting enough power to run, even though you thought you fully charged earlier.

More Tricks for iPhone Boot Loop Bug

Restore iPhone System with iTunes

Fortunately, besides using the product of FoneDog, you can always opt for the built-in feature of your iPhone to restore your system settings. However, remember that some files may be erased, whether you like it or not.

Either way, if you still insist on using built-in features of iPhone, then here are the steps to restore your system settings and fix the iPhone boot loop bug using iTunes:

Connect your iPhone device to a computer using a USB cable.
On your computer, open the iTunes.
Select the iPhone device that is showing signs of the iPhone boot loop from the list.
Go to the Summary section on the left side of the window.
Under the Manually backup and restore section, click on Restore.
Select a backup that you want to restore from, preferably a point in time when the iPhone boot loop bug is still non-existent.
Wait until the restore process is completed.

With that, you’ll be able to restore your iPhone without relying on any third-party software. But as previously mentioned, you will lose some files.

To give you a better idea of what those files may be, the files that you didn’t have when the backup as made will be deleted.

Update Your iTunes

As you may already know after seeing the previous solution, iTunes has something to do with your iPhone’s startup process.

iTunes is often used to update your iPhone device. However, if at that time, iTunes was malfunctioning, then the update might cause your device to malfunction as well. This is often the case when your iTunes is outdated.

And so, you should check your iTunes and fix any problem related to it by following these steps:

Launch the iTunes on the computer that you’re using it on.
Go to the Help menu at the bar at the top of the window.
Select Check for Updates.
There should be a set of instructions handed out to you automatically. You just have to follow the instructions.

With that, your iTunes will automatically update itself. Now all you have to do is wait for the process to complete.

But still, you can’t be guaranteed that iTunes is the culprit for the iPhone boot loop. So you should check out other solutions as well.

Force Reboot Your iPhone

One of the most famous solutions that are used by many people is the rebooting of the device with the problem. In this case, you’ll have to reboot your iPhone. However, it won’t be as easy as shutting down your iPhone and turning it on again.

After all, you won’t be able to follow the usual pattern when you’ve already entered the iPhone boot loop. So here are the steps for doing a “Force Reboot” on your device:

Press and hold the Home and Power button at the same time on your iPhone.
Wait until the logo of Apple shows up on the screen. At this point, you should finally release both buttons.
The Home screen should start to load up if the force reboot process is successful.

Obviously, this will only work if the problem isn’t that severe in the first place. So if the problem is actually worse than expected, it’s likely that this won’t work.

If that’s the case, you have another option of rebooting your device and escaping the iPhone boot loop, which is by using the Recovery Mode.

Boot iPhone with Recovery Mode

The Recovery Mode on the iPhone is usually used to do tasks that are only possible with your phone shut down.

It can be to install updates, add partitions, and in some cases, fix issues such as the iPhone boot loop. Either way, here’s how you can use the Recovery Mode:

Shut down your iPhone device.
With the iPhone turned off, press and hold the Power and Home button simultaneously like what you did when doing a Force Reboot.
When the screen turns on, connect your iPhone to the computer so that instead of the Apple logo, iTunes will show up on your screen instead.
At this point, release your Home button.
Now follow the steps to be displayed on the screen. This should take you to the actual steps to use the Recovery Mode.

Although it’s a different process, the end result is still the same. It would reboot your iPhone, but this time it would be more accurate and can work in even more severe cases.

However, rebooting your iPhone is only if the iPhone boot loop shows signs such as getting stuck to the loading screen. But what if the sign shown is that of a low battery sign?

Calibrate iPhone Battery

One of the signs that we discussed earlier is when your phone is showing red lines and contains zero percent battery when you were sure that you fully charge the device.

If that’s your situation, then here are the steps that will help you fix the iPhone boot loop bug:

Keep your iPhone running even if it’s stuck on a black screen until the battery percent is down to zero.
Now use another charger to charge the battery up to a hundred percent.
At this point, you should continue to charge the phone for at least 30 minutes.
Let it drain again until it’s down to zero percent and fully-charge it again.
Finally, reboot your iPhone using the steps we discussed in the previous sections.

After this, your iPhone’s battery should already be calibrated. This time, what you see on your iPhone is the real battery percent and not just a miscalculation.

Check Your Recently Installed Apps

Although it’s very rare, there are times when your iPhone device will get stuck to the Apple logo because of a malfunctioning app. As such, you should remember if you recently installed an app. If so, then try to connect your iPhone device to a computer then clear the data on that app.

With that, you’ll be able to delete the app without using your iPhone. Now, what if all these solutions aren’t working for you?

Talk to a Technician

Sometimes, it’s better to let an expert handle the situation.

This is especially true if the iPhone boot loop was caused by an update getting interrupted. This is because the damage cannot be undone through normal means.

It would only be solved if you have a technician fix the damage on the hardware, or you use a warranty for a free service or replacement.

Conclusion

As previously said, you shouldn’t worry if you’re encountering this problem often. It’s only natural considering that it’s a common issue for iPhone users. However, what’s different this time is that at this point in the article, you already know lots of solutions for the iPhone boot loop.

You won’t be having trouble fixing the problem this time. Regardless, you should still be careful since encountering the problem a lot of times can also lead to further damages.
