For programming your ESP8266 with arduino, connect pins like this:
(ESP left and arduino right)
TX -> TX
RX -> RX
IO0 -> Gnd
GND -> Gnd
RST -> 3.3V
VCC -> 3.3V
EN -> 3.3v
and in arduino do:
RESET -> GND
which tells arduino to just program ESP not arduino!
Just remove IO0 from Gnd and re-plug ESP's VCC or only connect VCC and GND to arduino!
