Okay so i've tried unrooting my phone and it definitely seems like it doesn't want to budge. It's running the Clean Continuum rom. Now i'd like to get 2.2(for Instagram and be up to date) but getting the OG firmware/rom for this isn't available anymore on XDA site so i'm kind of stuck. Is there another way I can revert back to stock? Like possibly factory reset or something a bit simplier?
