Wht i do bcoz my phone lockout for 8hours

You have been entering the wrong passcode for the phone.

Wait for 8 hours and then enter the correct passcode. If you continue to enter the wrong passcode, you will soon be completely locked out of your phone.

If that occurs, follow the instructions in this Apple Support document to reset the phone and then restore from a backup.

If you have additional issues feel free to reply to this thread or contact apple support.

Soon, you will be completely locked out of the phone. When that happens, follow the instructions that I have already provided for you above. Here they are again:
