I'd like to put stock 4.4 Kitkat on my Galaxy S4 (Sprint), but have some questions. Is it even possible at the moment? If so, what will I be missing/giving up with stock? How would I go about doing it? My phone is currently rooted, but I haven't really done much with it other than freezing a few apps that came with the phone and doing a few little things. Also, after it's done, if an update comes out (Be it 4.3, 4.4, or even something higher) will it wipe all that out?
