#21809 I have not been able to upload anything but the nodemcu firmware. using the recent 0.95 version as well as the new 0.96 dev version has the same result. baudrate for upload of firmware was 9600
I have tried lualoader by GeoNomad as well as lualoader by Hari Wiguna and esplorer with similar results. baudrate does not seem to be the issue. I have tried various pin setups such as; http://www.areresearch.net/2015/05/flas ... odule.html and http://i.imgur.com/Gts8osf.jpg. the wiring on the second link seems to work for uploading the firmware but not uploading lua to the esp8266.
My powersupply is very beefy as well, this should not be the issue.

#21828 Too long ago that I played with my working ESP8266-12.

I missed to connect GPIO00 and GPIO02, see table in this posting:
http://www.esp8266.com/viewtopic.php?f=13&t=3729

Now I did
IO0 -> GND
IO2 -> 3.3V

in addition to previously described cabling, still no success with esptool.py querying for flash_id at many baud rates including 74880 and 76800.

No idea on how to go further.
