Enabling Root For Tegra Graphics Debugger

I am developing a game for the Shield Tablet in Unity.

I want to use the Tegra Graphics Debugger for some performance analysis.
It looks like I have to enable root on the device to use the debugger - since I am not compiling the apk directly because I am using Unity,

What is the recommended way to enable root on the device?

There are tons of different links for this proces on the internet, and most of them seem to be posted by non-developers who dont even have TADP.

I understand that nvidia does not want to assume any liability for rooting, but since it is required to use the tool it would be very helpful to at least provide some unofficial guidance.

Thanks for any help/advice

Yes, there is no official root solution, but you can try to edit your project makefile manually to link with TGD libs, hope that helps.
