[ZTE Z7, Z7 Max, Z7 Mini] pnin:
​

I have seen Index threads on many forums here at XDA-Devs. I find this device needs one, since a lot of posts about it go to a help thread ([THREAD="2832760"][HELP] New ZTE Nubia z7 MAX[/THREAD]) that lacks a comprehensive first post, while others are getting posted to similar sounding but not fully compatible ZTE nubia Z7 Mini threads (like [THREAD="2916106"]this one[/THREAD]).

This is WIPo: If you want something to be added here, post it, and I'll try to keep it updated... :cowboy:​

DISCLAIMER: all credit goes to the respective posters (see end of present post); I own nothing and claim nothing (apart where I explicitly state otherwise); as usual, your device warranty is voided merely by reading beyond this point, so close your browser and go away if that's not what you intended...

NOTE: looks like Nubiaforums.com went offline a while back, so all links pointing there are now dead. I'm currently looking for valid replacements.

Most info concerning the NX505J was first posted to [THREAD="2832760"][HELP] New ZTE Nubia z7 MAX[/THREAD], so check it out.

Root/Recovery

[THREAD="2783157"]TowelRoot[/THREAD] seems to be the most consistent rooting method, although other methods may work (e.g., SRSRoot claims NX505J compatibility)
