I still remember the passcode. it just that my child entered incorrectly numerous times,and iPhone is locked since. I have tried to follow the link that you refer, and the step: "How to reset your device" section
- From your device's Lock Screen, try to enter your passcode five times until the "[Device] Unavailable" screen appears and your device asks you to try again later.
- When you're able to, continue to enter your passcode until the "Security Lockout" screen appears and you get the Erase [Device] option in the bottom corner of the screen.
iPhone does not provide me keypad or way to enter my passcode 5 times..
The only option I have is click on the Emergency for phone dial pad...
