Thank you very much, didn't know there were tickets, I'm pretty new to this since the Mirage is my first DNA
I took the 21700 off then on again, didn't start, switched the cable from usb 2 to usb 3 on the computer and then the miracle :
Windows Bip sound of heaven then EScribe said the firmware was incomplete : it reinstaled it from itself and then boom it was usable !
I even got my previous settings but I have close to zero idea on how this could have worked out, I'm just glad it's not a brick anymore
