Yes this does work 100%. I've had my N817 for over a year trying to root it, this method did it about a month ago, but I still haven't found a custom recovery yet. This is actually a very fast phone. It just has very low memory. It uses zram to enhance memory by default. I like to use swap on low ram devices, but this phone has issues with sd card, almost rendering the sd card useless. So I switched to internal drive swap.

THIS IS THE ONLY WAY THAT WORKS! GUARANTEED!!! I have recently discovered how to root my ZTE N817 quest. I looked allover used probably at least 20 programs the said they could root my device. I found one that would give me temp root but it would just disappear and go back to un-rooted. here are the files you will need and how I did it... 1. download Tunesgo trial. here https://tunesgo.wondershare.com/ 2. make sure its not the other software that they have but Tunesgo software. 3. run program and connect your phone via USB cable. 4. after the program runs and detects your phone select toolbox from the menu, then select one-click root. 5. it took close to about 20 - 30 minutess to root my phone. 6 Almost done.... This will leave you with a temp root or a disappearing root. 7. right after it says your phone is rooted, the run a small batch file that I created that installs SU and busy box. 8 this must be done right after away after running Tunesgo. after the batch file ends it will reboot you phone and you...
