...esptool.py erase_flash will completely wipe the broken filesystem, which is restored when you run the next deploy / write_flash.
I've corrupted a few filesystems by just using poor quality old usb cables. Easily fixed.

Done. The hard part will be getting MicroPython documentation updated for esptool.py.

uPyLoader fails to connect on a LoLin NodeMCU board by wifi or usb cable to PC if RXDO (GPIO3) is attached to modem TX, regardless of modem on/off. [TXD0 (GPIO1) and GND are attached to modem RX and GND respectively.] uPyLoader connects without problems by usb or wifi if RXD2 (GPIO13), TXD2 (GPIO15)...

@Roberthh - excellent!

Seems all possible but not with the hosted version I've been using. I should have looked through the issues: URL parameters for host and auto_connect already raised and workaround given but seems no active development.
