Uh, #3 just tells you to do what #1 told you to do.

Make Sure You Performed the Force Restart Correctly

It must be done exactly in this order:

1. Press Volume Up → quickly release
2. Press Volume Down → quickly release
3. Press & HOLD Side/Power button for 10–20 seconds

Keep holding the Side button ONLY — even if the Apple logo takes time to appear.

Many people release too early.

🔥 Important

If the screen stays black but the iPhone vibrates or makes sounds → this is a black screen / display failure, not a power failure.
