Pretty much everyone who was working on rooting the Z981 has abandoned the project. Just look at the main root request thread in the other forum, it is pretty much dead now and is dropping down more and more in the topic list. The Z981 has to be rooted first before the Z982 because they are very similar phones with the same kind of methods that ZTE used to make them extremely difficult or even impossible to get full root on. Even temp root is useless on them bcuz ZTE made sure that even that wouldn't get you anywhere as either it reboots almost instantly when you get it and DM Verity rolls backs any system level changes after reboot.
I have officially given up hope now and I am just going to live with what I've got until August '18 when the replacement to the Z982 is released bcuz the Blade could have been a much better phone but ZTE cut too many corners on this year's model. They should have went with at least the SD 625, 3GB of ram, and a down firing speaker that's 3X as loud as the current one. It would have also been nice if the rear facing cameras were the same as the ones on the Blade V8 Pro at 13+13MP or 16+16MP which would beat even that!
