In this part, we’ll figure out common solutions to get your iOS device to work again. Whether it’s a battery thing or simple software glitches, we’ll provide practical step-by-step methods to troubleshoot the problem. Let’s dive in and fix the issue now.

Force Restart Your iPhone

In most cases, you can repair the system or software glitches by performing a force restart. Differentiated from a standard restart, a force restart helps reset your device’s temporary settings and clears any software glitches during the iOS update. This is quite useful when your device is unresponsive or frozen. The steps of force restarting vary from different iOS models.

• iPhone 8 and Later:
  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Press and hold the Side button until the Apple logo appears.
• iPhone 7 and 7 Plus:
  1. Press and hold the Volume Down button and the Side button at the same time.
  2. Keep holding until you see the Apple logo.
• iPhone 6s and Earlier:
  1. Press and hold the Home button and the Top (or Side) button at the same time.
  2. Keep holding until the Apple logo appears.

Charge Your iPhone

If you cannot force restart your iPhone, it may be because your device is powered off. The update process can drain a significant amount of battery. If your iPhone remains on a black screen after a force restart, connect it to a charger and wait a few minutes. Once it has enough power, try restarting it to restore its functionality.

Fix iOS System Issues

If you still fail to turn on your iPhone after charging the battery, you may face iOS system issues. To get rid of the problems, consider using an iOS system repair tool. Among the most effective tools in 2025, BuhoRepair is worth a try. This tool specializes in fixing various common iOS system issues.

Step 5. Click Repair Now again and wait for the repair process to finish.

Restore Your iPhone via iTunes/Finder

If your iPhone still refuses to turn on after being charged for several minutes, put it in Recovery mode to fix it. The Recovery mode allows you to restore the device to factory settings and reinstall the operating system. In this way, you can address any issues that occurred during the update.

You can achieve this by connecting to iTunes or Finder. Here's how to restore your iPhone using iTunes or Finder:

1. Launch iTunes on Windows, or Finder on macOS Catalina and above.
2. Connect your iPhone to your computer via an original USB cable.
3. Put your iPhone into recovery mode.
4. Once Finder or iTunes detects your device, a window will pop up with two options - Update and Restore.
5. Select "Update" first. If no update is available, select "Restore iPhone" to reset your device and reinstall iOS.

Check for Hardware Issues

Sometimes, it isn’t software issues that prevent you from turning on your iOS devices. Instead, it may stem from physical damage or malfunctioning components. Hardware issues involve a faulty battery, a damaged charging port, or a bad component. By inspecting the hardware and internal components, you’ll see if any parts need to be repaired or replaced. Although this is always the last option you may work on, you should always check for your device’s hardware to make sure it can operate smoothly.
