Hi just to make sure since I don't really understand these stuff, what is the correct firmware for my phone?
Its
Region code: TUR
Bootloader version: I9300XXEMF6
BASEBAND VERSION: I9300XXEMA5
CSC: I9300OJVEMF1
PDA: I9300XXEMF6
I looked for the latest firmware for turkey but these codes were all different than mine. Where can I find the exact codes and latest firmware appropriate for my phone?

My problem is, I bought this phone clean then I rooted it now and the firmware ever since when I bought was 4.1. I want to unroot my phone to get back warranty and return my phone like how I bought it (such as be able to update firmware with samsung official method and not have to rely on any other alternatives and get rid of any other problems) so I found a tutorial to use triangle away then flash correct rom then reset in recovery mode. Will I be able to reach my goal?
