Just to check, you're using one of these?

Are you following this guide for Arduino setup?

  1. Hold down the GPIO0 button, the red LED will be lit
  2. While holding down GPIO0, click the RESET button
  3. Release RESET, then release GPIO0
  4. When you release the RESET button, the red LED will be lit dimly, this means it's ready to bootload
Are you seeing the behavior described for the red LED in the last step?

OK, sounds like bootloader is generally working. It's a ROM bootloader, so is essentially impossible to break.

What happens if you select the COM port for your USB/TTL convert and attempt to upload Blink?

Please post a photo of your setup showing how the USB/TTL cable is attached to the HUZZAH.

Swap TX/RX wires on one end.

HUZZAH TX should go to USB/TTL RX
HUZZAH RX should go to USB/TTL TX

See here for esptool troubleshooting:
https://docs.espressif.com/projects/esp ... oting.html

Is the problem repeatable?

Power is mentioned as a possible cause. Make sure the soldering on the V+ pin is good.
