Buttons for Akuma's Demon Flip?


#1

I can’t find this on any guides yet I have seen this move done in SFA3 A-ism and V-ism.
What are the buttons to do this and then the throw head first into the ground?


#2

Tiger Knee motion plus a punch button.

Towards or away +a punch button for the shoulder breaker

Towards or away plus a kick button for the pile driver
