hello @Bahrajj, i tried to contact the other guy but i hate when people say they are going to help you and then nothing! that's not very professional at all! so im not sure what happened there.
i tried to downgrade the phone to a sm-n950u and i couldn't. it wouldnt let me do so. i used the samsung tool program and odin and nothing happens. it get error.
when you say 'combination file' what do you mean? i see in the download secion some 'combination' files but im not sure which one is it.
i recieved this box, and bunch of cables and NO INSTRUCSTIONS WHATSOVER! the Z3X team assumes we all know what the heck is going on, also their videos on youtube are THE oldest i've ever seen. they have a new verizon and the ones on the videos are TOO OLD!
so... i am lost and ready to send this useless box (to me so far) back to them!
i need your advice. im willing to pay you if it's needed. thanks
