Vodafone stock


I downloaded nougat sometime ago on my S6 I don't know which version

I have since heard that there are some specific teams in the UK version so am looking for that.
However I have downloaded the Vodafone UK firmware both 6.1 and 7.0 and they both fail when I try to flash them.
Phone seems to be ok on the one I have I just want to get the right UK version .any idea why it fails

How did you update to Android N? Did you receive a OTA update or did you download the firmware and flash with Odin?
