This post highlights the downfall of putting all variants of the SGS3 into one section I'm afraid.
I'm using the International version of the S3, but so many times, the suggestions and help offered by others here only apply to certain variants, and, if someone is not careful, then sooner or later, an unwary person is going to come to grief by trying to flash a rom that isn't designed for their device.
Having said that, I'm still really happy with the Euphoria Lollipop rom, and would recommend it to any that have the same phone!
