Need to downgrade from 4.3 to 4.1.1
Hello, I bought a Family Mobile (powered by T-Mobile) SGH-T999L Samsung Galaxy S3 from Wal-Mart and it came with Android v4.3 installed. The phone is carrier locked apparently and I only bought it because they were out of Straight Talk GS3s. I had the intention to use a Bring Your Own Phone kit to switch it to Straight talk and run on the AT&T network but since it's carrier locked, I can't. I found a work around to unlock it, but it requires having v4.1.1 installed. I have Odin v3.09 and also have already downloaded my specific 4.1.1 needed, but as everyone seems to know, v4.3 won't let you downgrade. I am curious if there is a way to do this because in every thread I have read when someone asks this, the answers turn into ways to root. I don't need to root, I need to downgrade. Any help would be amazing because my wife is about to kill me.
