Hi, I have a Samsung Galaxy S3 (GT-i9300T Model) from Vodafone in Australia.I am wanting to flash an unbranded rom onto it using odin but I'm not sure of a few things. Will I be able to update my firmware normally without flashing it. Will I be able to use Kies. Also there is no GT-i9300T unbranded roms so I was looking at flashing a GT-i9300 rom instead. This will work fine right?
