Sonoff Installation

Hi guys,

I started to post on "Sonoff troubles" but I think my problem is now different.

I try to install Espruino on a simple Sonoff.

I download Espruino 1.94
I upload it to sonoff via Esptool after I had pressed the button and plugged in the module :

$ esptool.py --port /dev/ttyS8 write_flash 0 espruino_1v94_esp8266_combined_512.bin 
esptool.py v2.0.1
Connecting....

Chip is ESP8266

Wrote 524288 bytes (326519 compressed) at 0x00000000 in 28.7 seconds (effective 146.0 kbit/s)...
Hash of data verified.

Leaving...
Hard resetting...

It seems to be OK.
After that, I unplugged the module, repplugged it.
I'm not able to connect to Sonoff with Web IDE nor putty. Even if I've set baudrate to 115200 bd.

In WEB IDE I have "Connect" and a prompt ">" but I'm not able to type anything.

Do you have any idea ?

Thank you,
