MoKee ROM is an AOSP rom developed in China and based on CyanogenMod 12.1 but they reworked it pretty good. Even if there is a nightly version of CM 12.1 in progress they havent released one "official" yet. This version of MoKee it`s released as stable and good for daily use, but had a bug. 2nd SIM didn`t worked properly but they released a fix to flash over, that fix is included in ROM archive.
How too:
- you will need a custom recovery installed, I recomend to use phill`s recovery based on TWRP and ofcourse root enabled
- if you are comming from a stock rom it`s recommended to do a full wipe (/system, /data and /dalvik/ART)
- flash rom
- flash gapps
- do a factory reset
- reboot (this could take up to 5-10 mins so don`t panic)
- enjoy.
All credit goes too MoKee developers and the testers of this awesome ROM.
