Question A fatal error occurred: Failed to connect to ESP8266

[RiverQuartz]

Hello! Sorry if I may have posted this in the wrong section. I am currently working on setting up my nodeMCU (v1.0, esp8266-12E) board and I have done everything - not a single thing differed - from these Videos: Here and Here. At 14:30 on the first link I get this:
esptool.py v1.2
Connecting...

A fatal error occurred: Failed to connect to ESP8266
.
Thats it, no other error codes/logs are given to help the case.

Any help would be greatly appreacted!!!
Warmly, River

This error indicates that your controller cannot communicate with SPI. It could be hardware problem (wrong wiring, fauly CPU/device), or improper software configuration.

I don't think anyone has time to watch the videos in order to understand what you are doing:

• What is your hardware?
• What OS is on your RPi? (although the video title does not mention RPi but Arduino)?
• What kind of device is your 8266?
• What is the connection between CPU and esp?
