NodeMCU uploading problems

Hello,
I've tried uploading code in my ModeMCU ESP-12 0.9 (v1) but when I upload the code (it's a blink code I took from the examples), I have the following errors and warnings:
Warning: espcomm_send_command: wrong direction/command: 0x00, expected 0x01 0x08
Warning: espcomm_send_command: wrong direction/command: 0x00, expected 0x01 0x08

Warning: espcomm_sync failed

I use Linux 16.04 LTS (32 bits)
I use Arduino 1.6.13
I use NodeMcu ESP-12 0.9 (aka v1)

And I already tried:
-D0 to RST or GND
-GPIO0 to RST or GND
-Flash Button
-Changing USB cable

Thanks, I am so sick and tired of this problem (I spent all day yesterday).

Help !
