Many of us are using 6.0.1 with this device. And we can tell you would want to root this device... otherwise you wouldn't be here.

To root the device you are required to downgrade to 5.1.1. Recently ZTE has removed all the official ROMs for this device that contain 5.1.1 files. This was the most common way to downgrade, by downloading these files and side loading them with ADB. However, I have found a Romanian version of the 5.1.1 ROM that is suitable for the root process.

You will need:
Vodafone Smart Ultra 6
A computer
ADB Platform tools
Micro-USB Cable

Firstly, download the platform-tools.zip from: https://developer.android.com/studio...platform-tools
-extract the platform-tools.zip and place the folder anywhere on your computer.

Secondly, download the Romanian stock ROM from: https://bit.ly/2IwkUCT
-extract it and move the update.zip folder into the platform-tools folder.

Lastly, download the TWRP recovery from: https://androidfilehost.com/?fid=24591000424952165

Now, make sure you have the Android USB Drivers installed. You can download from here: https://developer.android.com/studio/run/win-usb

Now that is out of the way, lets flash the ROM onto your phone.

Reboot the phone into recovery. (Power button + VOL up (release the power button 2 seconds after "powered by android" logo, otherwise it will reboot)) Also plug in the phone to PC.

Now, select 'Apply update from adb'.

On the computer, head to the platform-tools folder and open CMD with that directory. (you know, the cd C:blah\blah\blah)

Type in
Code:
adb devices
to check if your device is detected by the computer. If it shows the device name along with sideload, then it is fine.

Then, type in
Code:
adb sideload update.zip
Wait until the process is complete and the phone says 'Install from ADB was complete.' in the bottom left of the screen on the phone.

Reboot the phone and you should see Android 5.1.1 setup screen in the Romanian language. Set it to the language you desire and connect to Wi-Fi. Log into your Google Account and do not set up a lock on the phone.

Now, head to Google Chrome and download KingRoot apk: https://kingroot.net/
Install the APK and try to root. It should work.

Now, go into Google Play Store, and install Rashr Flash Tool: https://play.google.com/store/apps/d...tools&hl=en_GB

Move the TWRP recovery img file from the PC to the phone, and then open the Rashr Flash App and grant root permissions.
Scroll down till you see the 'Recovery from Storage' option. Select that and flash the recovery img.

Now, that should work. When it is complete, find and download the custom ROM you would like to flash. In my case, I will be using the MIUI 7 ROM. (links of other ROMs below.)

Transfer it to the phone and reboot to recovery. Once you are in recovery, wipe everything except internal storage and flash the ROM. After flashing, then you can wipe internal storage and reboot. You can also root if you desire.

You have now installed a custom recovery and a custom ROM to your phone. Give ya self a pat on the back.

List of ROMs you can install on this device:

Notice about link
Hey everyone, it just occurred to me that the link is broken, thanks to the person who contacted me about this via PM. I'm not active with this thread as i forgot to subscribe to it since the start of this thread (heheh, sorry). I still have the file on my PC and I re-uploaded it to mediafire; which you can find here: http://www.mediafire.com/file/mr2mdg...pdate.zip/file

Feel free to contact me on my Telegram: t.me/yomarshmellow

Hey, happy to help!

Open Command Prompt (CMD) on your computer and browse to the directory of your platform-tools folder.

command example: cd C:\platform-tools
- I suggest keeping your platform-tools in the root directory of your C: Drive to access it quickly

Alternatively, go to the platform-tools folder with Windows Explorer, and SHIFT+RIGHT CLICK inside the folder. Then select "Open powershell window here" After that, type in cmd for the first command and continue with the guide.

If you have "open command prompt window here" then that is fine, you don't have to type in cmd.

I'm sorry for replying late, but if you need more direct help, contact me on Telegram: t.me/yomarshmellow

Good luck!

Hello,

I must have done something wrong since I can't do anything.
I tried to install again by sideload the ROM provided but it is giving an error.
The message is:
"This package is for "P839V55" product; this is a "omni_p839v55".
Updater process ended with ERROR: 7

Can someone help?

Thanks for the link. The rom has Google FRP enabled, so to bypass it, I followed this vid:

I'm not sure how safe this guys APK is, but it did work. If there's an easier / better way to bypass FRP, please let us know.
