i was on the zte grand x max plus rooting thread and i found this written by Christopherco
I have gained system r/w access through this process : open terminal and type su You should get # Then type : dd if=/dev/block/platform/msm_sdcc.1/by-name/boot of=/dev/block/platform/msm_sdcc.1/by-name/recovery Then I type : reboot recovery when my phone booted back up, I had full rights and deleted some system apps. When I rebooted again I no longer had full rights but the system apps did not come back. This is just one more step towards full rights over system. Hope this helps.
i tried it on my zmax running cynanogen and it seems to work. just wanted to state it
