[Jet-Fighter7700]

Hi Guys,

I wanted to ask all the android sleuths out there
I have one of these phones:

a ZTE MAXX, but it seems all the forums are confused as to what exactly it corresponds to?

ive gotten this,

and this
https://www.zteusa.com/zte-max-duo-straighttalk

as well as this:

more specifically no page or equivalent on XDA devs for it, not sure where to start looking for a replacement ROM,
