If your iPhone still won't turn on after attempting a force restart, here are several troubleshooting steps you can follow:
Charge Your iPhone
- Connect to Power: Ensure that your iPhone is charged. Use the original charger and cable, and let it charge for at least 30 minutes. Sometimes, if the battery is too low, the device may not respond to a force restart[1][2].Check for Hardware Issues
- Inspect for Damage: Look for any signs of physical or liquid damage. If your iPhone has been exposed to water or has physical damage, these could prevent it from turning on[1][4].Perform a DFU Restore
- Enter DFU Mode: If charging doesn't help, you might need to restore your iPhone using Device Firmware Update (DFU) mode. This is a deeper restore option that can fix serious software issues:1. Connect your iPhone to a computer.
2. Open Finder (on macOS Catalina and later) or iTunes (on older macOS or Windows).
3. For iPhone 8 or later: Quickly press and release the volume up button, then the volume down button, and press and hold the side button until the screen goes black. Continue holding the side button while pressing the volume down button for about five seconds. Release the side button but continue holding the volume down until your device appears in Finder/iTunes.
4. Follow the prompts to restore your device[2][4].
Recovery Mode
- Use Recovery Mode: Similar to DFU mode, recovery mode can help restore your device:1. Connect your iPhone to a computer.
2. Follow the force restart steps specific to your model until you see the recovery mode screen.
3. Choose "Update" when prompted; this will attempt to reinstall iOS without erasing your data[4][5].
Seek Professional Help
- Visit an Apple Store: If none of these methods work, it may be time to consult with professionals. Take your device to an Apple Store or an authorized service provider for diagnosis and repair[5][6].Following these steps should help you address the issue with your iPhone not turning on after a force restart.
