I did try that image and it works, some caveats though:
Bought a cheap 64GB microSD class 10 from microcenter, seems it's a fake, don't know for sure I'm formatting it again, but it failed writing the image. Had a sandisk one (also 64GB) and that worked just fine.
The image provided seems to want the IR keyboard, that gets overwritten if you put a physical keyboard on the USB but I couldn't get the software keyboard to come up. Maybe I have to do some research for that. Maybe if I put a display and touchscreen and that might work.
but it works, tried HULU and plays fine, as for my purpose I couldn't install the playstore seek thermal app, but I hope the SDK version will run, or if I sideload the app it might work. Not enough time right now to test it all.
