Code: Select allesptool.py --port COM16 --baud 115200 write_flash -fm qio -fs 4m 0x00000 nodemcu20161005.bin 0x7C000 esp_init_data_default.bin

That looks correct for modules with 512kB flash size. I assume you followed http://nodemcu.readthedocs.io/en/master ... g-firmware.

Could it be that the NodeMCU version does not match the esp_init_data_default.bin version? Is nodemcu20161005.bin from the current NodeMCU master branch? How was that binary built?

Now i solve problem
I do like this:
esptool.py --port COM16 --baud 115200 write_flash -fm qio -fs 4m 0x00000 nodemcu20161005.bin 0x7C000 esp_init_data_default.bin 0x3fc000 esp_init_data_default.bin

erase program dont solvd problem, only write to both memory alocation.
