Nowhere Flyme OS firmware download for Meizu Pro 6S?

I search all day and I can’t find anywhere flyme os firmware for Meizu Pro 6s. Only for Meizu Pro 6. I am thinking buying Meizu Pro 6s but in case that my phone needs reflasing where I can donwload it’s firmware? It’s frustrating that Meizu pro 6s doesn’t even appears as a device even in the forum or the global site. It’s like that not even Meizu support this model. It doesn’t appears anywhere and that’s the reason I haven’t bought it yet. Can I install Meizu Pro 6 firmware on Pro 6s or it has it’s own?
