Yes, I have rich experience in programming but not in embedded devices like Phicomm N1 box, so I have to learn a lot before doing anything on it. But it’s a good idea to make a deeply customized version of EmuELEC(plus some TV app, whatever it is), which will give me the maximum freedom.
Actually, I don’t care about Android or Linux at all, because what I need is playing emulating games and watching TV(and videos stored in NAS or Cloud) on my N1 box. But there are no integrated solutions, so I have to choose a suboptimal one which is happen to be EmuELEC+Android TV.
Dual-boot of CE+EE is not only technically possible but actually doable and I achieved it in April. All stuffs are open-source as the project HybridELEC
You’ll need to either port the older USB burning tool flashable HybridELEC I made for Xiaomi mibox3/3c (MDZ-16-AA) which I ended support, or add N1 support to new Amlogic-ng only HybridELEC (the hybrid-ng branch) and ampart.
