Android Central Question
I have a Samsung Galaxy S7 G930A (ATT) and I am trying to restore it to Android 6.0.1 from Android 8.0.0. I am having a really hard time finding a Stock ROM for my phone. I downloaded two of them from different websites. Loading them into Odin 3.13 goes just fine, but When I click on start, it gives an error message saying "FAIL! (Auth)" I have tried as much as I can but can't seem to figure this out. Anything Helps!
