Here's a custom rom for ZTE N939ST V5 PRO. You should install it by recovery. It is multiligual with latest Play Store v6.05, and I removed all chinese apps.
1. You should need to root first,
download UPDATE-SuperSU-v2.46.zip and put it as it is in the root of your SD card in the phone
After step 2 once you have placed ui.zip into the folder "theme", you will install UPDATE-SuperSU-v2.46.zip which will give the ability to root your device.
2. Then you should put english translation for the recovery.
download ui.zip file
In the internal memory, at the root, you may find a directory named "TWRP", if not create it. Create another dirrectory inside TWRP, you may name it "theme". Put the file "ui.zip" as it is in theme directory.
the directory would be <storage>/TWRP/theme/
3. Download the recovery tool to access the recovery menu.
The file is: Recovery_Z5pro.zip
Unzip it into your computer's desktop in a folder you can name "recovery". Open the folder and launch start_recovery.bat, meanwhile press power and volume (-) until you feel your phone vibrates after rebooting. In the "Dos windows", follow the steps, press enter. Your phone may have entered into recovery mode.
Go tho the backup menu. Make a backup of your phone, it will create in /TWRP/BACKUPS a directory named with letters and figures (ie: 7g2564rt, that was on my phone, yours may be different), after the backup, there will be a directory of the backup just made.
At the same time, from your computer you can see through a window explorer that your device is present, go to it, in external memory go to /TWRP/BACKUPS/"ie: 7g2564rt"/ , create there a directory named new_firmware , then unzip there the CM.
Go back to the phone go the menu restore, go to the directory "new_firmware", make a retore with it. When done, reboot your phone, choose your langage,that's it. Tested fully functional with touch id and everything !
