Need Custom Rom for my Huawei Honor 3c

Currently i use the Cynagogenmod 13 resurrection but it is to buggy.

I search a rom with no bugs. Android 5.x.x or 6.x.x
i like to install the xposed framework, is there any chance on my H30-U10 ?

Is there a way to go to 5.x.x with official updates? Must i go back to the official stock 4.4.x and upgrade?

thanks for help.
