Are the At&t and Verizon motherboards the same in the LG G Vista?

Hi, my dad broke his LG G Vista and i am trying to see if the phone still works. There's no flex to the device so i am hoping that i can put a battery in and power it on to at least get the contacts off the phone and onto his iPhone that is now is using. i am looking at a DOA At&t model on ebay and was wondering. Are the motherboard layouts the same that i could swap the boards around and at least use the phone again if it work? I am going to barrow a battery from a friend to use to do a power test on it so if it works i can use software on my laptop to control the phone but i might want to fix it for fun in the future and this would work as a DOA phone i don't really care about.
