Got a Reverb G2 replacement cable, but it still doesn't turn on

[xKenn]

Hi guys, I bought the HP Reverb G2 VR headset 7 months ago. It randomly stopped working, the LED HP logo on the headset no longer lights up when plugged in. Today, I received a replacement cable but it still doesn't work. Would like to make sure I've covered all my grounds troubleshooting before sending my headset back for a complete replacement...

When I plug in the USB, Windows make the notification sound, and I see a new "Generic SuperSpeed USB Hub" in device manager.  But I no longer see “Mixed Reality Devices” like it used to, nor do I see any extra "monitors". Mixed Reality Portal doesn't open automatically either, it just shows "connect your headset" if I run it manually. The white LED on the dongle lights up, so I know the device is being powered. The headset also gets a little warm (near the connector area) if I keep it plugged in, despite no LED (HP logo), no display/sound.

Things I’ve tried:
-Plugging it into a different DisplayPort/USB 3.0 port/Powered USB 3.0 Hub
-Updating graphics driver

-Reinstalling graphics driver
-Updating USB driver (Yes, my eXtensible host Controller is updated.)

-Updating HoloLens Sensors driver

-Unplugging everything and plugging it back in

-Restarting my computer

-Updating Windows 10

-Updating BIOS

-Plugging the USB-C into the adapter "flipped" (Yes, I know it doesn't make a difference but I'm desperate lol)
