Part 3. How to Fix iPhone Won't Go into DFU Mode?

If you've tried the correct steps but your iPhone won't go into DFU mode, don't worry. The following fixes are arranged from simple to advanced, helping you systematically identify and solve the problem.

Fix 1. Check the USB Cable and Port

Among all possible causes, connection issues are the most commonly overlooked but also the most frequent factor. DFU mode relies on the computer recognizing the device, and if the connection is unstable, the process can fail even if the steps are done correctly.

Therefore, before attempting more complex solutions, it's recommended to start troubleshooting with the basic hardware connections.

Step 1. Use the original Lightning cable or MFi-certified cable.

Step 2. Connect the cable directly to a USB port on the computer (avoid using a USB hub).

Step 3. Try different USB ports (preferably use a motherboard port).

Step 4. If possible, try connecting to a different computer.

Fix 2. Force Restart the iPhone

If your iPhone isn't entering DFU mode, you can try a force restart, which can resolve minor iOS glitches and refresh the system.

• Force restart iPhone 8 and later: Press and release the "Volume Up" button, then press and release the "Volume Down" button. Next, press and hold the "Power" button and release it when the Apple logo appears.
• Force restart iPhone 7/7 Plus: Press and hold both the "Volume Down" and "Power" buttons together. Release them when the Apple logo appears.
• Force restart iPhone 6 and earlier: Press and hold both the "Home" and "Power" buttons together. Release them when the Apple logo shows up on your iPhone.

Fix 3. Update to the Latest iOS Version

If your device is running an older system version, there may be compatibility issues or system bugs that prevent your iPhone from going into DFU mode. It is recommended to update your iPhone to the latest iOS version and then try entering DFU mode again.

Here is how to do it:

Step 1. Open the "Settings" app and tap on "General".

Step 2. Select "Software Update" to check for any available updates.

Step 3. Tap "Download and Install" to get the latest iOS software. (iPhone won't update?)

Step 4. Once your iPhone restarts, follow the correct instructions to try entering DFU mode again.

Fix 4. Contact Apple Support

If you have tried all the methods above but still can't enter DFU mode, it's likely a hardware issue, such as a damaged button or motherboard malfunction. In this case, continuing to troubleshoot on your own may not be effective, so it's recommended to seek official support.
