The serial output at 74880 baud is simply this:
ets Jan 8 2013,rst cause:2, boot mode:(3,6)
After that no response.
I tried to re-flash NodeMCI with PyFlasher.
It shows this output
Connecting....
Detecting chip type... ESP8266
Chip is ESP8266EX
Uploading stub...
Running stub...
Stub running...
Configuring flash size...
Warning: Could not auto-detect Flash size (FlashID=0x0, SizeID=0x0), defaulting to 4MB
Flash params set to 0x0240
Compressed 410448 bytes to 264293...
After that nothing.
If I select "Erase Flash" the last status reported is
Erasing flash (this may take a while)...
I've let it sit for hours, and it never proceeds beyond that message.
What is the next step to resolve?
