To address everyone -- no, there doesn't seem to really be any difference between the the 8GB and 16GB variants. Aside from RAM and storage, the two are otherwise identical. I spent last night unlocking the bootloader, flashing TWRP (I was totally prepared to start working on porting, but someone saved me the trouble), rooting and removing all of the Amazon nonsense.
It took HOURS to pull down the AOSP source because Nougat source code was just released and everyone has been just hammering the google servers. That being said, I have my dev box built and my environment is in place. I'm looking at the Mediatek source code right now and trying to figure out where everything goes and what everything is called. I'm hoping to be able to successfully compile the kernel source in the next week or so.
please be patient with me. bear in mind that a kernel that compiles is not necessarily one that boots. And it certainly doesn't mean Im going to have a working port of CM13 (or 14) any time soon. Also, I have a real job outside of android dev work and thats what pays the bills.
Are there any other devs working on this right now? Has anyone else figured out if mediatek does anything non-standard with their toolchain?
