Why are you sure that it is a fake??
if you tried to download it
you will find a survey and you won't be able to download
Whatsapp servers are up again
If you are facing the same issue then change the network of sim2
from: auto connect LTE/3G/2G
to : 3G only or 2G only
that's it and problem will be solved
This is CM 13 rom
I found it on chinese forum and tested it and it is working perfect with me
So I wanted to share it with you
Also me use 30a rooted.. And obviously Artshell that uploaded it pre-root.. Flashable zip, Somehow managed also to root..
