Flash android tablet with custom GUI made by using c / c++ like emwin QT

Question

I have a question i came across embedded software development. I can programme gui and flash Arm Cortex m3/m4 proceesors with spi I2c uart bus interfaces. I can make decent gui on it using libraries like qt or emwin.

My question is can i flash android tablet with my own gui on it. I mean i dont want android os on my tablet. Can i flash my own custom firmware on android tablet. Where do i get the schematic of those tablets and is there any project on web like this.

Please dont put comments like why you want to do it. My question is simple can i / we do it if yes than how please.

Thank You !!!

The closest you can get is running PostmarketOS , which is Linux Distribution with GNU userland for Android Devices. Developing a custom firmware is hardwork. Checkout the PostmarketOS website for the list of devices Compatible.
