@MaBe So a quick update -- the ESP-201 is supposed to come with only 4mbit flash, and this is even supported by many photos online (at least I guess of early chips), but mine for whatever reason have 8mbit parts (maybe they ran out at the factory of the 4mbit flash? Who knows). This is what caused the problem. So I guess you can never assume anything in the ESP world :P

So I did erase the flash and use the following as per the README (adjusted for 8mbit flash):
```
esptool.py --port [/dev/ttyUSB0|COM1] --baud 115200 write_flash \
  --flash_freq 40m --flash_mode qio --flash_size 8m \
  0x0000 "boot_v1.6.bin" 0x1000 espruino_esp8266_user1.bin 
  0xFC000 esp_init_data_default.bin 0xFE000 blank.bin
```
and now it works, and thus no need for the combined file. Anyways so if anyone else has an ESP-201 board and is having problems flashing, please check the part size for the flash.
