Xposed Framework didn't seem to work.. I can install it fine and I even did this....
"With a proper build.prop editor:
Find this line: ro.config.hwtheme=1 (or 2, it depends on your device)
Change to: ro.config.hwtheme=0
This will disable Huawei Theme Engine
WITH THIS YOU DON'T NEED TO DISABLE RESOURCE HOOKS"
But it still doesn't activate, i'm guessing because writing to the /System is being blocked by Huawei.
There's also a warning message about using Xposed with Huawei roms as Huawei uses a theme engine too.
So I don't know.. If I had a way to make a snapshot backup i'd go a little deeper. But it seem troublesome...
