Easiest way would be to flash a different (older, newer) version, do a file.format() there and re-flash your target firmware.

Thank you, that did a bit of the trick!!!

I spend some time on google to find an old version of NodeMCU, flashed it, restarted the ESP8266, and it is back working. But when I flash the newest version, it is stuck again.

UPDATE
I found a dev version of NodeMCU, flashed it, did the file.format() flashed current release again, and it is working! Hell yeah! This is valuable information for next time it goes wrong, because it most likely will again.

Also have a look at https://github.com/nodemcu/nodemcu-firm ... s/init.lua Using a timer in init.lua will avoid such lock-up in the future
