• So you're a lucky guy, it's working fast for you for 2 different esp8266 based boards..
    I really don't understand what's wrong with my nodemcu-e12. I don't have any other esp8266 to try. I installed mine with the same files, but using esptool. If I install last espressif firmware before, it wont make a difference, it will be erased by esptool, right ?
    I still get a slow download. Honestly, I don't know where to go from here.

    python esptool.py --port COM20 --baud 115200 write_flash --flash_freq 80m --flash_mode qio --flash_size 32m 0x0000 boot_v1.6.bin 0x1000 espruino_esp8266_user1.bin 0x3FC000 esp_init_data_default.bin 0x3FE000 blank.bin
