What will happen if I flash it?

Hey, what will happen if I flash N910F full stock rom (including b/l, modem etc)? I have the N910G variant and I really wish to update to lollipop but there hasn't been any news for it in like literally a month. I live in Australia so if I do lose some bands, there are still ones that are compatible with Australia.



Also is it just me or is KitKat stock so laggy and slow? I get battery drain and overheating. I had a Note 3 before and never experienced any of these issues...



Thanks Guys! :good:
