Latest version of Cyanogen Mod a k a CM12 is now available for download courtesy of XDA. Of course to flash the cyanogenmod for Moto E 2015, you will need its custom recovery. We recommend TWRP for Moto E 2015 which is more user friendly.
Here is what is working out of box:
* GPU accelerated graphics
* Camera preview (but not picture taking)
* QSEECOM keystore
* Accelerometer (and auto-rotation)
* Adaptive brightness
* Media codecs
The only thing that can give you some problems is wifi which is a bit slow in detecting networks and then connecting to them. You can download it from here. To flash it onto your Moto E 2015, simply put it onto the micro SD card slot or internal storage. Boot into TWRP and flash it from there.
