Supported models that can be rooted by this method are SM-G950U/U1 and SM-G955U/U1 models in the US, and SM-G950W and SM-G955W models in Canada.

But there is a catch that you need to be on a certain version of Android OS in order to root your device. This method is working for Snapdragon S8 and S8 Plus variants.
