I was still having problem with the Corsair headset shutting down after the bootloader fix. In fact, I do not believe it was a bootloader issue, but rather the way Windows 10 was over charging the headphone. Here's how to fix it: go to Control Panel --> go to power options --> advanced settings --> USB suspend settings --> Change this to Disabled. Also, you can charge the headset in a wall socket or if you're charging on your computer, don't turn off the headset - just plug it in to power. You can long-hold the power button to turn on the headset if you plug it into a USB wall socket. If nothing is working, you can try opening the right cup (not the one with the mic) with a small screw driver and loosen the battery?
