I bought this one Ebay, and Tmobile said I'd need to reset fully, or get the password. Sooo...I read online where I can hold down the DOWN volume, then the hang up, then the call, and enter reset mode. Check! It said reset mode for a second. And then it went to a screen with "!" and a picture of a phone. That can't be good. I haven't touched it since, as I'm not sure if it's trying to do something. It doesn't look like it's doing anything. Where do I go from here?
