DISCLAIMER: I AM NOT RESPONSIBLE FOR WHAT MAY HAPPEN TO YOUR DEVICE, DO THIS AT YOUR OWN RISK.

Before I start: everything I'm going to post here, I learned from this thread: https://xdaforums.com/maven-3/help/zte-maven-3-z835-root-t3705687/page9

VERSION OF MAGISK FLASHEAD v17.1 (Unfortunately no one has flashed version v18.1)

What we need (they will be in the links at the end):

-ZPST for AT&T (with this program we are going to flash the modified boot.img)

-Drivers: QDLoader, ZTE AndroidUSB and ZTE_V889F (in case the previous Zte driver does not work).

-Modified boot.img that are already flashed with Magisk, only the following versions are available:

-Z835V2.0.0B10

-Z835V2.0.0B12

-Z835V1.0.0B13

-Magisk Manager version compatible with v17.1

EVERYTHING YOU NEED IS IN A LINK AT THE END OF THE POST.

Let's get started.

I recommend to do a hard reset before starting, however, in one of my devices I did it having data and applications installed, if you have used kingroot or any other software in your phone, erase all trace of it so you do not have problems.

We download all the contents of the folder, install all drivers included, and the ZPST for AT&T.

Starting to flash:

WE NEED AT LEAST 50-60% of Battery

Turn off the phone and turn on pressing Vol Down + Power Button, the phone will start in FTM mode.

Open ZPST for AT&T and select version Z835

WARNING, remove the usim and sd card

Once inside the software we proceed to connect the cell phone.

1. You will see if the phone was recognized by the com port.

2. Download, this is where we will enter to download the firmware

3. You will see your information imei and so on.

3. HIT THE DOWNLOAD BUTTON!!!!!

WARNING: wait for the device to restart at least 2 or 3 times, one of them will be in FTM mode again, so do not panic, it will take a while in 3% or 5%.

When the phone starts normally, if you did a hard reset configure everything again, otherwise, we will proceed to install the magisk.

DO NOT INSERT THE SD CARD YET!

Magisk asks if I want to update to the latest version, press NO THANKS.

Proceed to uninstall

[IMG="MG2"]https://fotos.subefotos.com/fdaad5c949d25800fda509cfa041873fo.png[/IMG]

Now let's install the version of magisk manager we downloaded (com.topjohnwu.magisk_6.1.0-165_minAPI21(nodpi)_apkmirror.com.apk)

[IMG="MG3"]https://fotos.subefotos.com/c2762587cae04a00828cfe79dee4b4ffo.png[/IMG]

When the installation is finished we enter Magisk and this will ask us if we want to upgrade to the latest version, PRESS NO!

[IMG="mg4"]https://fotos.subefotos.com/d8cfebfad4b6f4722a02f27c2d1dd5fbo.png[/IMG]

Now we will see that magisk is installed correctly.

[IMG="mg5"]https://fotos.subefotos.com/6c258d9a3379a044320ca66ac14c40ddo.png[/IMG]

We see that we can use all its functions.
