NodeMCU flash fails - "Connecting to HW-BELTLINE-01"

I have a NodeMCU dev board based on the ESP 12E chipset that does not want to flash. I've tried with both NodeMCU-PyFlasher-4.0 and exptool.py v2.7.

Here's the output from NodeMCU when attempting to flash a firmware:

Command: esptool.py --port /dev/cu.SLAB_USBtoUART --baud 115200 --after no_reset write_flash --flash_mode dout 0x00000 /Volumes/Users/troy/Downloads/tasmota.bin --erase-all

esptool.py v2.6
Serial port /dev/cu.SLAB_USBtoUART
Connecting........_____....._____....._____.....___

Connecting to the serial port using screen /dev/tty.SLAB_USBtoUART 115200 and resetting the device gives the following:

�#�p~�o�lNo���cp��l{l{lp�o��$��co�|l����#�|~�o�l��$`�2oN$`Ns���o��l r��n���l �N�

Connecting to HW-BELTLINE-01
...........................

The . continue on for ever.

The same results occur when using a discrete FTDI USB to UART device connected to the relevant TX/RX headers and powering the board via headers as well (so, taking the USB to UART chip out of the equation).

Any suggestions on how to get some firmware onto this device, or is it DOA with something not connected properly?

Default firmware tries to connect to the HW-BELTLINE-01 ssid wlan, open or protected with HKHK123HW password. If it succeeds, you can call /gpio/0 or /gpio/1 to test your device.
