I tried it today and it works. Only used the diode that connects to gpio0 and the capacitor. I didn't used the other 2 diodes. The diode I used is a regular 1N4002. It doesn't work everytime, because sometimes it gives me the "espcomm_upload_mem failed" but it gave me that error before when I used the buttons method and I could see clearly that the ESP8266 is in flash mode in serial command window. So this circuit is not the problem of that error.
Thank you Charles!
