here is an nvflash that supports cardhu(tegra 3), this is for linux, its all use so all i have, i just issued the --sync command and have not gotten an unknown device error, just getting nvflash started, then it just sits there.
i havent used nvflash really at all, im just used to fastboot and adb, but hopefully this helps and i dont have much time today or tomorrow at all to mess with it.
Linux users- in your rules.d(android-rules-whtever you want to make it) first line will get ADB working with the prime, second should allow it to be seen in APX mode:
SUBSYSTEM=="usb", SYSFS{idVendor}=="0b05", MODE="0666"
SUBSYSTEM=="usb", SYSFS{idVendor}=="0955", MODE="0666"

Edit after messing with some nvflash commands I get a "USB write failed" error, which after Googling tells me Asus has used an SBK(secure boot key), rendering nvflash useless(unless asus gives it to us-128 bit encryption). Basically locked, encrypted bootloader and were f#$ked.
I really hope I'm wrong.
