Nope, the device has 4.5 on it. I've followed the instructions in "what to do next...", loaded latest OS, but device still has same IT policy. Tried going through "How do I wipe..." FAQ again with new OS, nothing happens, I never get the 507 screen. Feels like I'm going in circles. If you can't use method one, How do you resettofactory using the apploader? I must be overlooking something.
