Recently I have been working with ESP8266 ESP-03 and decided to flash it with NodeMCU. Looking at how to do this ( here ) it seemed to be pretty straight. forward task.

However when I started to try and flash the module I have not received any results. Most of the cases module became unresponsive. After many hours ( really ) of looking for some guideline where the problem can be I have came across post which referenced to write the default data into 2 memory addresses of the module.

So I have done so with the following command and that has helped – now got my nodemcu running as it should be!


Hope this will help you if you have been looking for some tips!
