Okay so here's the deal. I bought this phone of craigslist, and activated it right away, and everything was great. But of course he had his gmail account set up, so went through the "privacy" setting and did the reset data clear option. My phone powered down, and started back up, but gets stuck on the moto logo, and wont boot back up. If I pull the battery, it will start back up to normal, but still with his account. If I try the reset by powering down, holding power and X nothing happens and it ends up frozen with the M lolo again. I tried using the camera button instead of X, and then is just powered up normally without reseting. I have made calls, and sent text just fine. He said it wasn't rooted. I don't know how to tell. Need some help as I can't access the app store without my account set up, among other reasons. Thanks
