get the bin file for your device:
https://github.com/xoseperez/espurna/releases

setup the hardware as described. Im using an FTDI cable this shows in my system as /dev/tty.usbserial-FTE384H9 and is used in the following examples

set GPIO 0 low 
check with console that you see boot mode message

install esptool if needed
pip install esptool

sudo python /Library/Python/2.7/site-packages/esptool.py --port /dev/tty.usbserial-FTE384H9 --baud 74880 erase_flash                           130 ↵  10054  08:39:25

open a serial console at 115200
disconnect GPIO 0 so its no longer grounded and power cycle if everyting went ok you should see the following message
