I have a Verizon Note 3 that I am trying to use on AT&T and I am having a few issues that I can not figure out how to fix. After a few calls to tech support, I have come to the conclusion that they are worthless! My question, which I believe would fix all my problems is whether or not I can flash the AT&T stock Rom on the Verizon one to make it think it is actually an AT&T phone. My LTE will not currently work and from the research I have done it does not seem like that will be able to function only H and H+. I am also having a weird issue that nobody has seemed to hear of....when I receive an incoming mms message it creates a whole new thread that looks like the person I was chatting with and myself have sent me the text message. Somebody please help me!
