I own a Samsung Galaxy S4 Active GT-I9295 (international version) and I recently unrooted my device so I can update my OS. I try to update my OS as I'm currently running 4.2.2 but when I check for updates it notifies me saying "Your device has been modified. Software updates are not available" and looking at the status of my phone, it says its "custom".
I want to be able to fix this and update to KitKat but I don't know where to start or what firware to choose. When searching the database on SamMobile, I came across this ( sammobile.com/firmwares/download/34604/I9295XXUCNH2_I9295BTUCNH1_BTU.zip/ ) but its the UK version (I live in the USA). Does it matter what country I select for the firmware? Do I need to match the PDA, CSC, or MODEM codes to my existing phone/firmware of that from the link? Will this brick my device or am I clear to apply this using Odin? Sorry for probably the very basic questions but Im very new to these kind of things.
