esp8266 save() wrong js code, auto reset and crash

Hi,

I have a nodemcu board (esp8266-esp12). I saved a wrong js code into. Now I can't save a new working code.

I got this from the chrome ide:

I reflashed with this command (as i flashed first time the espruino firmware):

./esptool -bm qio -bz 512K -bf 40 -cp /dev/ttyUSB0 -cb 115200 -cd nodemcu -ca 0x00000 -cf espruino_esp8266_board_0x00000.bin -ca 0x10000 -cf espruino_esp8266_board_0x10000.bin

I installed arduino dev. env. And successfully uploaded wifi and blink code to it, so the board is working. After that I re flashed the espruino binaries, but it's is wrong.

What can I do to continue develop js code, and can save a new working code?

regards
HyGy
