I just recently rooted my Samsung Galaxy Ace 3 so I can get FW 4.4. Reason why I want 4.4 is because so I can play Pokémon Go. So yeah, I rooted my phone and have no idea how to install it. I know that you need "custom recovery" but the thing which is pushing my away is that I think I need to factory reset it which I don't want do to. I know I can use Odin but not sure if I need to factory reset to use it correctly. So yeah, it would be great if you guys give me answers because, I am not good at finding answers on the internet.
