The "weekend" project I call VortexColor was in fact bring Android 4.1.2 for a "Chinese" tablet called imported by UNUSUAL called Vortex Color powered by a Cortex-A9 chip. I was lucky to find that the company released the whole sources of their tablet for Android 4.0.4 so we managed to build CyanogenMod 10 for it with just some issues during the compiling process.
Due to the tab was not mine, I just could work a weekend on it. We managed to create 4 different versions of the ROM. Last one though, less buggy than the official 4.0.4 release.
As all my works, everything is published on Github to share with everyone all the knowledge I learned on that amazing project.
Special thanks to Blerfont, another developer that helped me on the creation of that ROM.
