If you use virtual box, that's what I used, make sure you select Linux in the first, then other Linux x86/x64 in the second as the operating system, then you start the machine, it comes up with a box asking what you are using to boot the os. Select the little folder icon and manually locate the .iso file, double click it and it will take a second to boot. I had to click the USB icon on the bottom of the virtual box and select the zte one to make it see the device, then when you enter the command and it says waiting on device to boot, when you screen on your phone is black click the USB icon again and click the zte option again. It will boot your phone into the pseudo recovery. Flash recovery and flash the superuser and reboot your phone. You should now have root and recovery
