Yes, but 3.1 is not 3.0. I apologize if it has been answered before and I do assure you I have searched but came up with nothing relevant to 3.0. In the end, I made a backup, I flashed it myself, and the difference is huge when recording slow motion, a lot more light comes through. So if anyone wants to try, I do recommend it.
