maan, I dont mean to harp or bother you but why dont you open-source it right now? There are SO many talented coders here and around the world, and I aspire to at least become..somewhat competent. It could speed up fixing whatever youre struggling with in the code. Someone, who knows maybe a Xiaomi-dev would make some suggestions on how to fix things, and that'll be that.
I hope you take my post in the right way, Im fully supporting you but releasing alpha-software is in the spirit of the open-source world. It has to start somewhere right? I know as a perfectionist myself Im never satisified with whatever I do, something I struggle with everyday,, but maybe thats just me.
Anyhow, I really do believe if you open-source this project it would be at least have the potential to faster become what you imagine the perfect Linux-distro running on this amazing tablet.
Cheers
