Recently I bought Samsung Galaxy S4 I9505. Unlocked and updated to KitKat 4.4.2. It was used i CH for a very short time, but now, it will be used in BiH. Somewhere I read that KitKat was distributed for different regions, so as phone is moved from CH to BiH, I want to do fresh install of KitKat.
From where should I download appropriate KitKat and what is the easiest way to install fresh KitKat, and also root my phone?
