APX Mode (USB debug)

APX Mode can be used to run Fusee Gelee or use Nvidia tools to flash the hardware. https://forum.xda-developers.com/showpost.php?p=77286176&postcount=85 "Power off the device. When the device is properly shutdown (not sleep mode!) plug in your USB type A to type A plug (it has a male usb on each end) from your Surface USB port into another computer USB port. I did this with a computer running Linux but it should work with any operating system. It's important you have the cable connected, it seems the RCM APX mode doesn't reestablish a connection if the cable is missing or removed. At least that's what I observed when I unplugged the cable while in RCM APX mode. With the cable in place hold both the power and the volume up key down simultaneously for a few seconds and then let go of the power while keeping the volume up key held down for a few more seconds then let go. If successful you should see some sort of USB based "NVIDIA Corp." device appear."
