Hi.. So I need to unroot and return to stock everything with every rooting related flag reset since it is required for my office's BES client. I've gone through every tutorial online, and what I didn't do was reinstall the stock ROM, since I already was on the stock ROM, however, I did at one point change to CWM but then reinstalled stock recovery; even after trying nearly everything I haven't been able to get all the flags set to official/normal while being unrooted, I did achieve an OTAable device while being rooted though... I wanted to know whether the CSC code (or the product code? check here, all other codes match up with my device) (INU/INS for my region) is the one that I see in the stock recovery when it loads up. It says INS then says something of the sort of "multi CSC" complete etc. For my region I can see two such codes for official ROMS on sammobile, INU and INS. Please help.. this seems to be the last piece of the puzzle.
