OK so I was out and droped my phone , it froze and I couldnt unlock it. I took the battery out and it would get stuck on the screen that says samsung. I looked all over the internet and found a way that should have fixed it. All it did was take my verizon phone and put at&t on it and so now all it does is load up a white at&t screen. I cant get it to go into downloading mode by holding the volume buttons what do I do now. I had previously rooted it, and as such the warrentys void but I figured that if I ever needed to fix it Id factory reset it but I cant even do that so I assume I am screwed.
