I dont really know how to do it myself but its your factory rom. You can flash that ROM back with Odin at anytime. I think since Ive done this so much, I remember the way I have everything on my phone the way I like it and its fun to re-apply it all. Infused is what I had and Infused is great. But now that I have a replacement, I think im just gonna wait to see what Samsungs push of GB offers. If its not a big difference, Ill go back to Infused since there gonna update it with GB very soon.
