Hello, guys long time I haven't done anything to Samsung phones and need some quick help:

Current phone: G930F Unlocked and Branded to Region code XEG (1&1, Germany) (Not rooted)

Mission is to debrand this phone and attach it to a UK Region. Hard Reset not a problem, but main thing is to keep receiving OTA Updates.

I downloaded the original UK BTU Rom

Do I need to use re-partition option?
