CM 13 for MT6592 is an aftermarket ROM based on Android Marshmallow. CM 13 for MT6592 is now more stable compared to it's first build. This is also the latest Snapshot build of Cyanogenmod 13. To know what's working and what's not working, look for it down below. ROM is really really smooth and has Multiwindow as well. Overall, this ROM can be used for testing and maybe also as a daily driver if you do not want Camera and Bluetooth.
Note : This ROM can be ported to any MT6592 device running Android Kitkat 4.4.x with kernel 3.4.67
