None of the 1 click root methods work on 4.4.2 here is a copy of the guide in our forums on a how too. Its tough and not easy and fast but here you go.
This is gonna be a quick setup guide for the virtual machine called virtual box. Here is the download link for Virtual box:

The unbrick tool:

Here is the adb driver i used in this set up because windows needs to see the device as adb able:

Superuser:

And finally philz recover:
http://d-h.st/I6A(make sure you click the bottom download link on this page, the top one sends you to an ad)
After you download the virtualbox.exe , go ahead and install it, i left all the settings alone.
This is what it should look like after you install it. Next you will want to click new.
I named the machine Unbrick tool for the sake of this guide. Choose linux as the top option and oracle 32 as the bottom. Again after setting those 2 options i left all the other settings alone for setting this up so just keep clicking next and you should be fine. Note- This is what worked for me. You should wind up with it looking like this now.
Now click start and you will get a new window pop up.
You will want to click the folder option i highlighted in the picture above. this opens a file finder, now just go to your unbrick tool download location and select the iso. it should now look like this.
Now click start.You will get an option screen, just choose the top one by pressing enter. On the computer i was using i got a popup for sound, it is not needed for this but for the programs sake just choose either one.
Your virtual machine should now be booted and look like this.
Click open the folder with the lable my documents, go to the folder in that called ZTE unbrick tool, inside that folder right click the partions folder and left click the open in terminal.
Type the following in the terminal:
adb reboot bootloader (Here you may have to right click on the little usb icon and selected the zte option)
(you will need to accept something on the device at this point or it will say the device is unauthorized)- thius will be a usb debugging athorization window, click always allow and then accept.
Once you are in bootloader type:
fastboot boot stormer_mmcblk0p16_recovery.img (again after you type this you will have to right click the usb icon i showed above and choose the zte option or you phone will just hang in the black screen (ie. the boot loader) waiting for a command)
(this will boot your device into PhilZ recovery. It will not install it, just boot to it. You will have the ability to use it as normal until you reboot)
Now i assume you will all know how to use recovery, flash your recover.zip (if you are following this guide it will be the philz recovery) and flash the superuser.zip. This will give you recovery and root back after you have used the ota update to upgrade your phone. Hope this helps anyone having trouble with the usb/cd live option. I take no responsibility for any harm this may cause you (ie. explding phone syndrom, catching your house on fire, and any freak acts of nature) Enjoy
