Hi People!
Due to a stupid misunderstanding, my brother rooted my new S4 when I was at work, when I didn't want it rooted. I believe he did it correctly because it all works fine. However, I want to unroot it again in case I ever need the warranty. I've done a lot of reading about this, but don't seem to be able to find exactly which firmware I need. I've connected my phone to Kies and it tells me that my firmware is I9505XXUFNB8. I was told to check Sammobile which I did, but the only firmware that matches that version number seems to be for a French carrier (France NJR).
Does anyone have any idea how I can find the correct firmware?
