Hi, I Can't update to V3.02 via RootJoy, it fails and shows this message please root your phone, check the root authority allow
I've tried rooting the phone using all of the main rooting tools Eg iRoot, Kingo Root etc but it fails every time.
It seems that Umi have prevented the Iron Pro from being rooted but won't allow flashing of the updated official rom unless it's rooted!!
please help!!
