Nubia Z9 Mini SuperSU root tutorial

There is already a tutorial on how to root the Z9 mini but it uses Kinguser as the root method.
I rooted my phone using the Kinguser method but was unable to use titanium backup or lucky patcher for that matter.. (Whats the use when it doesn't work with two of my favorite apps. lol).
This tutorial takes it one step further and changes the root from Kinguser to SuperSU !!

STEP 1 : ROOT using Kinguser


After downloading the above files, extract them.
Open that folder and run the file named as “r-o-o-t.bat”. A command window will appear in your PC screen.
Now connect your device to PC using USB data cable.
Enter the number "1" in command window and wait for the program to process your entry.
Once you see the message “Waiting for devices” in the command window, switch off your smartphone,
press the Volume down button and Power button until you see the Boot Menu.
Once you see the Boot Menu in your device, press Reboot to begin the rooting process.
Congrats!! Your ZTE Nubia Z9 Mini is rooted now but unfortunately with Kinguser.

STEP 2 : Change Kinguser to SuperSU.

This is where the fun begins. As I am not sure on which Custom recovery to use.. I just went ahead with using terminal to install SuperSU and replace Kinguser.


Steps :

Send the extracted folder "mrw" to the root of SD card and make sure that this folder contains 6 files
Open Terminal emulator and type :
This grants root permission to terminal emulator.

Next type
and press enter.

It might display some error, at the end it will launch SuperSU. (open SuperSU manually if it doesn't)
Update su binary using normal method, then reboot.

Now All apps that require root will work without issues..!!:laugh:
