Here are five methods to solve the problem of your mobile phone not turning on after iOS 17 update, according to your actual situation to choose the method that suits you.
If your iPhone is running low on power during the update process, then it may not turn on due to lack of power. Therefore, charging your phone and checking if it responds is a necessary first step. You should connect your iPhone to the charger that came with it or another Apple-certified charger. If the iPhone not charging, there may be a problem with the charging device.
You need to check all the parts of the charging device including the USB cable, jack, and power adapter. If they are all fine, then you may need to visit an Apple Authorized Repair Store to troubleshoot the device's hardware.
If your iphone fails to turn on after iOS 17/18 update, you can try to force restart your iPhone. Please note that the method for performing a force restart will be different. According to Apple's official website, iOS 17/18 is only compatible with iPhone SE (2nd generation or later) and newer models. Any models preceding iPhone SE are not supported by iOS 17/18.
Here are instructions for force restart those models: Press and quickly release the Volume Up button, followed by pressing and quickly releasing the Volume Down button. Then, press and hold the Power button on the side until the Apple logo appears.
If your iPhone still fails to start up correctly, refer to the next method.
If none of the above steps work, your iPhone might need to be restored using Recovery Mode. This is a more advanced solution that can reinstall the operating system without affecting your data. It is recommended to back up your device to ensure that your data can be restored if necessary.
Step 1: Make sure you have the latest version of iTunes on your computer. You can access the Apple website to download it.
Step 2: Connect your device to your computer with a USB cable and launch the iTunes application. (Use Finder if you’re on macOS Catalina or later.)
Step 3: Follow the force reboot steps relevant to your model, but keep holding the Side or Top button even after the Apple logo appears. Release the button only when you see the recovery mode screen.
Step 4: On your computer, you should see a prompt with options to "Restore" or "Update" your iPhone. Choose "Update" to reinstall iOS without erasing your data.
If the update doesn’t fix the issue, you may need to choose "Restore," but be aware that this will erase all data on your iPhone.
Device Firmware Update (DFU) mode is the most in-depth type of iPhone restore and can be used if Recovery Mode doesn’t work.
Step 1: Connect your iPhone to your computer and put your iPhone into DFU mode.
Step 2: If your computer detects the iPhone in DFU mode, you can open iTunes or Finder. Then click OK and Restore to restore your iPhone.

Once you’ve successfully fixed your iPhone, take these steps to prevent the problem from happening again:
1. Keep Your Battery Charged: Always ensure your iPhone has a sufficient charge before starting an update. It’s best to perform updates with your device plugged into a power source to avoid any interruptions.
2. Back Up Your iPhone Regularly: Get into the habit of backing up your iPhone before every update. You can use iCloud or iTunes/Finder to create backups. This ensures that you won’t lose important data if something goes wrong during the update process.
3. Avoid Interrupting Updates: Once an update has started, allow it to finish completely. Interrupting an update—whether by turning off your device or disconnecting it from a power source—can lead to software corruption and prevent your iPhone from turning on.
4. Use Only Apple-Certified Chargers: Using third-party chargers, especially cheap or unverified ones, can damage your iPhone’s battery and lead to issues during updates. Stick to Apple-certified accessories to ensure your phone’s safety.
Q1: Will I lose my data if I perform a force reboot on my iPhone?
No, it will not erase your data. It simply forces your iPhone to reboot, which can resolve many software-related issues.
Q2: What should I do if my iPhone won’t turn on even after charging and performing a hard reset?
If your iPhone is still unresponsive, try entering Recovery Mode to update or restore your device. If that doesn’t work, DFU mode is a more advanced option, or you may need to visit an Apple Store or authorized service provider.
Q3: Can an iPhone update permanently damage my device?
While rare, it is possible for an update to expose existing hardware issues or corrupt critical system files, leading to problems that may require professional repair.
Dealing with an iPhone that won’t turn on after an update can be stressful, but with the right approach, it’s often a solvable problem. By following the steps outlined in this guide, you can troubleshoot and potentially fix the issue.
