You may need to provide external 3.3.v power to the sonoff. (I tried using a raspberry pi zero with an old power supply and it did not provide enough power for the pi and the sonoff.) See sigmdels website above for a wiring diagram.
If you power the Sonoff with the 3.3v power from the RPi it will cause it to reboot when connecting. You can still enter flash mode if you power up the RPi with the 3.3v connected and pressing the button on Sonoff simultaneously. It's recommended to use either an external power supply for this or use the 5V GPIO and a 3.3V Voltage Regulator.

**Do not connect 3,3V yet!**
