How can I downgrade 5.0 Android to 4.4?

[AC Question]

Hello. First of all I really want to say how I love your site and forum and this anonymous "ask anything" feature. But to the question: How can I downgrade my brand new Samsung Galaxy S5 (SM-G900M) Android 5.0 to 4.4? I've looked firmwares everywhere but I could only find some Spanish ones from sammobiles/firmware

I'm from Finland so I would prefer the language to be Finland but if the firmware if English for example, is it possible to somehow install a finnish language on it? I'm really sorry but I'm such a noob when it comes to things like this. I basically want to install 4.4 but with finnish language. Can you please help me?

Welcome to Android Central! You need to install the firmware specific to your model, so search for the exact model number on SamMobile. You can change the system language in Settings>Language and Input.
