Swift 2X - Nougat Manual update?

Is there any place I can download the 2X nougat firmware to manually flash it? The system update doesn't seem to work for me. There is this: http://www.stechguide.com/install-android-7-1-2-nougat-on-wileyfox-swift-2/ but I am first not sure how trustworthy the download links are and second i am not sure if Swift 2/2X need different firmware.
