You must press the button at power on and keep it pressed.
On Sonoff devices this is a bit tricky as those buttons often are not that great so it is quite hard to keep it pressed.

N.B. never (ever!!!!) connect your PC to the Sonoff when it is connected to mains voltage.

About the power, I know, read before on web, but thank !

Yep, the button on Sonoff devices is always (as far as I know) connected to GPIO-0.
By pressing it, you pull the GPIO down, which is needed to enter flash mode.
