problem activating droid bionic...please read/help if you can
I guess the kid I got this droid bionic from tried to unlock it for AT&T and I guess he messed it up. I tried activating it, got the 4g sim card and then when I try activating it, it says something like after trying to activate your 3g phone the 4g sim card will no longer work blah blah blah and i was talking to verizon and they were saying the kid did something to make the bionic a 3g phone and I need to try to make it back to a 4g. I don't know if that means returning the phone back to stock or what. I did a factory reset and that didn't seem to do much and I tried unrooting it but not sure if that's the problem or not. Kind of a noob here so I was wondering if anyone knew how to do this or if there's anything I can do because they were saying I'd have to mail it in to motorola and have them repair it but I'd rather have that as a last resort but if anyone can help I'd really appreciate it
