[Moto X] Hard brick, green light, that's all

[galabean]

Hello,

I have a big problem : after a bad flash of firmware or ROM, my Moto X don't want to turn on anymore.
When I plug in to the wall stock charger, I saw a green light but it disappears quickly.
When i plug into the computer, it appears like an HID device 5 secondes, then disappears, then appears, etc.

After reading a lot of topic here, I saw that a factory cable could be the solution.
I bought one online and I just received it.

The differences I saw with this cable : on the wall charger, now, the green light is still present, it doesn't disappear like the other cable.
The other difference is that it appears in the device manager of my computer like an "Unknown USB Device (Device Descriptor Request Failed)".
I tried the fastboot devices, and it doesn't recognize it.
I tried to install the qhusb load, but Windows won't let me saying that the previous driver is already the best.

And no matter what button I pushed, in no matter the order, the screen won't never turn on.

If someone could help me, I would be very very very very happy
(I only hope it's not dead )

Thank you !!

I have a Moto X XT1058 that is hard bricked, it would not turn on, not even the green light.
I followed this tutorial, and managed to get the device into the bootloader, but can't still manage to flash a ROM.

I tried to install the qhusb load, but Windows won't let me saying that the previous driver is already the best.

I had to look for a different installer than the one provided in the tutorial, it was a .exe installer, not through device manager.

I think I have the installer in my downloads, if you want the one that worked for me, send me a private message or give me your email to send you a google drive link with the file.
I don't know if I can share it through here.
