Unable to upload to Node Mcu ESP8266 E-12

Hello everyone. I just bought an ESP8266 breakout, more specifically: https://goo.gl/jusJD5 The issue I'm having is I cannot upload anything to it. I have the board, COM port and baud all set properly and I have tried messing with the baud with no luck. I have tried holding pressing and all kinds of combinations of the RST and FLASH buttons on the board. Maybe I'm doing it wrong. Heres the error I get:

warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed

Thanks in advance
