Default Go back to stock (TWPR)

Hi,

I have a troubleshooting : I can't get into download mode... So I can't got my G pad back to stock :s
I'm running CM 11 and TWPR 2.6.3.1
I tried to hold Power and vol down / Power and vol Up / Power and Vol up + down but It always boot into CM11...

What can i do ?

Edit : I found the solution myself...

1) Hold Vol up and down
2) Plug the USB
3) Don't touch the power key
