I got the rom "working". It is AOSP Kitkat 4.4.2 with ElementalX Kernel.
But it has random reboots, and many things related to video etc do not work.
Need some days of testing, but the hardest part I think is done already.
I need to check many things, like vendor files and libraries.
I can put the link for the most daring to try, but as I tell you is a beta. You choose if you want to see it.
