How to Fix the iPhone 6 Blue Screen of Death (BSOD)

If your iPhone 6 randomly flashes a blue screen and then reboots—or worse, gets stuck in a restart loop—you might be dealing with what many call the iPhone “Blue Screen of Death.” This issue isn’t limited to just one app or action. It can happen during a FaceTime call, while browsing, or even when your phone is idle. Some users also get stuck on the Apple logo or recovery screen afterward.

Here’s what you can do to try and fix it.

---

1. Force Restart Your iPhone

Sometimes a simple forced restart can snap your iPhone out of the blue screen loop.

• Press and hold both the Home button and the Power (Sleep/Wake) button.
• Keep holding until the screen turns off and you see the Apple logo again.
• If the screen stays black, go to the next step.

2. Put Your iPhone into Recovery Mode

If your phone stays unresponsive, or if the blue screen keeps coming back, try entering recovery mode and restoring via iTunes or Finder.

Here’s how to do it:

1. Open iTunes on your computer (or Finder if you’re using macOS Catalina or later).
2. Do NOT connect your iPhone yet.
3. On your iPhone, press and hold the Home button.
4. While holding the Home button, plug in your iPhone using a Lightning cable.
5. Keep holding the Home button until you see the “Connect to iTunes” screen.
6. Your computer should show a message saying it has detected an iPhone in recovery mode.
7. Click Restore when prompted.

⚠️ Note: Restoring will erase your data, so only proceed if you’ve backed up your phone or have no other option.

3. Try DFU Mode (If Recovery Mode Doesn’t Work)

If recovery mode fails or you’re still getting iTunes errors like 9 or 40, put your iPhone into DFU (Device Firmware Update) mode:

1. Connect your iPhone to your computer via Lightning cable.
2. On iPhone 6 or 6 Plus:
   • Hold Power + Home for 8 seconds.
   • Release Power, but continue holding Home for another 5–10 seconds.
3. If the screen stays completely black, you’ve entered DFU mode.
4. iTunes/Finder will prompt you to Restore.

Still getting error 40 or 9? These usually point to hardware problems, possibly with the logic board or NAND chip. You may need to contact Apple or a trusted repair service.

4. Update iOS After Restoring

If you manage to get your phone working again, make sure to update iOS to the latest version. Apple occasionally patches bugs that may trigger these types of crashes.

• Go to Settings > General > Software Update.
