[Moto X Force] Stock rom

Hi guys,

Thanks to the work of some of you like @damkol, i was able to unlock my BL, root my MXF and install Xposed framework without any trouble.
The Xposed addon works great......
.... But, for some reason (6.0 OTA which didn't work, Good for enterprise application which can't work on rooted device,...), i would like to find a way to flash my MXF with a stock rom...

Is there is a way to obtain a system image from a trusted source ?

Thanks in advance.
