Excuse me if I take your comment with a grain of salt. Too many different stories, from different people. On the phone, a rep tells me that ZTE can open access to our bootloader, but probably won't, and online they say they don't even support unlock for the axon 7 which is a lie. On the phone rep says, ZTE doesn't have any intentions of giving the ZMAX pro nougat, on the went chat, I'm told we should see it sometime q1 of this year.
On another note, seems that I'm not having the luck some of you are with temp root through KingRoot. No matter what version I install, it only gets to 70% before failing. There is a site with paid rooting software, that claims to be able to root the ZMAX pro, but I've gotten no response from the developers of the app....
