Dev, Please try the following 1.) Install Kingo PC, and root with it. It will report successful. 2.) before restart ,remove the Kingo superuser app (you have to remove the kingo superuser in order to gain root access on your phone, super weird. ) at this point Titanium report root access with Kingo Binary, and Freeze System app looks like working Flashify seems like working, but I there is not a Zmax2 twrp yet Root Checker report successful as well. 3) After restart, no long root access I hope this is a good start, and hopefully a real Dev can start from here. Good luck everyone.
