We loved NVIDIA Shield's bone stock Jelly Bean OS in our review, but if you're not a huge fan, NVIDIA's now offering a way to dig in and customize your Shield's OS even more. NVIDIA's made the Shield's software open source as of today, making the OS all the easier to customize. You'll of course have to root your device and, ya know, have an idea of what you're doing in the guts of a computer. NVIDIA warns new owners as much, saying, "To be sure, this is double-diamond stuff. If you're not a coder or already set up with an Android development environment you should skip downloading these tools."
The company's blog post also notes that rooting your Shield or adding a bootloader will potentially void your device's warranty, so hacker beware! Should the associated tasks and NVIDIA's warnings not scare you off, the software is available right here. Our review video of the Shield is just below, in case you missed it last week.
