Firmware update from Mac failed.

  • So, I was following the instructions to update the firmware, however, when I Cura's Automatic Update prompt came up it said my firmware update version was UNKNOWN, so I grabbed the .hex file for the version the latest version from GitHub (probably my mistake), and told it to update. Immediately my Mac USB disconnected and the Cura said the printer was no longer connected. The LEDs went green then red and it stayed in that position for a long time. So, now my Sigma won't boot and when I try to turn it on the right extruder goes left and hits the other extruder and starts making noise. Any chance there is a way to manually update the firmware without Cura? I cannot connect Cura to the machine anymore it won't recognize the Sigma. I am stuck and opened a support ticket with BCN3D. Any advice.
