I know this question has been asked a fair amount but all I see is nonsense that I get confused with. I have a stock Samsung 4.3 ROM with my CSC (NZC) and I want to flash it on a stock Android 4.4 ROM (BTU). How is this achieved? Can I extract a TAR or create a flashable ZIP?
Also is it possible to achieve this without doing a full wipe?
The 4.3 ROM I currently have is 19505XXUEMK9_I9505NZCEMK2_I9505XXUEMK9.TAR
The 4.4 ROM I have is
Thanks in advance for your assistance.
