Broken feather M0

[Enivo]

hello there
So, i just bought a feather M0 bluefruit (PID 2995) and i manage to use it quite well with my 32x64 matrices trought a shield (PID 3036).
But now i have a probleme. I can't flash it and the matrices doesn't show anything anymore.
It is reconized by my PC and i can open it like a USB key
the red LED in pin 13 increases and decreases is brightness
did i killed it ?

also here is the error that arduino gave me :
java.io.IOException: Cannot run program "{runtime.tools.bossac-1.7.0.path}/bossac": CreateProcess error=2, Le fichier spécifié est introuvable

Make sure you have both the Arduino and Adafruit SAMD board files installed and up to date.
