I found this to be interesting.
I've began a support request to get the boot loader unlock codes and explicitly began requesting the GPL code (parts of Android and their Linux kernel source). This should give me a few options.
They may or may not decline giving me the boot loader codes. Not the end of the world.
They are legally obligated to give me certain source code for what's running on this device. Such as the linux kernel with the modifications they've made. If they don't provide this source in it's entirety, then there's some legal implications involved there. The first response from their support was pretty ignorant. They linked me to some download section of their website that only had developer SDKs, not the sources I was requiring of them.
Anyway, once I have the kernel source, if no bootloader codes are provided, I can begin scouring it for ways to elevate to root at least.
