Since I have a custom recovery I cant update via OTA, so I decided to flash the update via ODIN. However I'm not sure which build should I flash, I see that there are several like :
I9300XXUGMK6 → I9300XXUGMK7 → I9300XXUGML2 → I9300UBUGML3 → I9300XWUGML4
Could you explain the differences between them? Also, which country should I flash for? My country region is Bulgaria, and the CSC showed VVT. However I saw that they have the older MK6 version. Whats gonna happen if I flash a build from different country? Thanks.
