iPhone 16 won't turn on after black screen during iOS update

You are using an iPhone 15 Pro, which uses a USB-C interface and supports entering DFU mode to force a system recovery.

🧰 Preparation:

A computer with Finder (Mac) or iTunes (Windows).

A USB-C data cable to connect your iPhone and computer.

Keep your iPhone connected to the computer and do not disconnect it during the whole process.

📲 Steps to enter DFU mode on iPhone 15 Pro (follow step by step):

✅ Step 1: Start with the phone turned off (you are already in this state)

The phone is now black and only displays the battery icon. It doesn’t matter, just continue the operation.

✅ Step 2: Enter DFU by pressing the key combination (the following actions are quick and continuous)

Quickly press the volume + (upper left)

Quickly press the volume - (lower left)

Then immediately press and hold the power button (the "action button" on the right) for about 10 seconds until the screen goes black (if it is not black)

Next, continue to hold the power button while pressing the volume - button

Press and hold both keys for about 5 seconds

Release the power button after 5 seconds, but continue to hold the volume - button

Press and hold the volume - button for about 10 seconds until the computer detects that the iPhone has entered recovery mode, but the phone screen remains black.

✅ Sign of success:

Finder (Mac) or iTunes (Windows) pops up a prompt window:

"An iPhone in recovery mode has been detected and needs to be updated or restored."

If you see the Apple logo or battery icon, the operation failed, try again.

🛠️ Next you can choose:

Update: Try to retain data to repair the system.

Restore: Will clear data and reinstall the system (suitable for cases where the system has completely crashed).

Me too, have you solved this problem?

This works, good luck
