Hey guys whats up. I got my replacement phone. So I went ahead and followed the steps to Unroot and put back the original Software with the phone. I used Odin and the proper Software. Now when the Unroot and Software process was done. the phone reboots and then I get Unfortunatly Googleplay services has stopped. I then hit ok. and then another pop up says the samething. I hit Ok and then the phone reboots. And it is in like a constant boot like this. Is there anything I can do about this? I really dont want to send back the phone to them like this. Or do you think it is ok? Well hope someone can help me thanks guys
