If the firmware files from above flash correctly but after reboot you see only garbage on the serial and/or the LED on GPIO2 is flashing rapidly, try to re-initialize this sector: download https://github.com/espressif/ESP8266_NONOS_SDK/blob/master/bin/esp_init_data_default_v08.bin and flash it to 0x7c000 for 512 kB modules (some ESP-01, Sonoff Switch), 0xfc000 for 1 MB modules (most ESP-01), or 0x3fc000 for 4 MB modules (most ESP-12, Wemos D1).
