TRACE +0.109 Timed out waiting for packet header

[ghost]

I can't upload the ESP sketch, and its giving me this errors:
TRACE +0.000 Write 46 bytes:
c000082400000000 0007071220555555 | ...$........ UUU

5555555555555555 5555555555c0 | UUUUUUUUUUUUU.
TRACE +0.109 Timed out waiting for packet header

Iam using the ESPTOOL on win.
I connected the two metal circles, without sucess.
Note: Every time that i start trying to upload the skecht my board blinks a blue light.
This is the command am using>

esptool.py --trace --baud 150200 --port COM5 write_flash 0x00000 C:/Users/MyUser/Desktop/esp8266_wifi_duck_4mb.bin --flash_size 4MB --flash_mode dio --flash_freq 40m

I'm experiencing the same behavior, I've also tried changing the baud rate to 115200 without success. my command is:
python esptool.py --trace --baud 115200 --port COM5 write_flash 0x00000 esp8266_wifi_duck_4mb.bin --flash_size 4MB --flash_mode dio --flash_freq 40m

Also, last line before execution completes is:
A fatal error occurred: Failed to connect to Espressif device: Timed out waiting for packet header

Hey, EuphoriaDealer, I've found a solution to successfully flash the ESP8266. Instead of his CLI Python-based flasher, NODEMCU has a GUI-based flasher here that worked for me. I'll put it in a google drive folder for you here.

In the program you can configure the parameters as he stated in his python command, and I had the bridge connected before connecting to usb and the entire time during the flash. In other words, I didn't disconnect the bridge until the flash was over. Let me know if this works for you!
