The ZTE Spro 2 is an Android-based portable projector that has WiFi and LTE connectivity – basically, its Android built into a screen projector, so you can stream Netflix over the projectors data connection while projecting the image on a nearby wall.

Because it is an Android-based device, we can root the ZTE Spro 2. Now, why would you want to root a screen projector The answer is quite simple – an unrooted ZTE Spro 2 will display its image at 200 lumens of brightness while connected to a charger , but drops to 100 lumens while on battery. In short, the ZTE Spro 2 forces you to see a darker picture quality if youre not charging it.

By rooting the ZTE Spro 2, you can override this limitation and adjust the brightness of the projector regardless of whether you are charging or not. Some users have also managed to get Xposed working on their rooted ZTE Spro 2, but thats beyond the scope of this guide, although its entirely possible.

For this operation, we will initially root with KingoRoot, which grants us a temporary root ( restarts on reboot) , so we will then replace KingoRoot with SuperSU to get a permanent root .

Requirements:

  • ADB & Fastboot (see Appuals guide “How to install ADB on Windows”)
  • KingoRoot APK
  • Lumens Fix APK

How to root the ZTE Spro 2

  1. Download the KingoRoot APK file from above and transfer it to your phones SD card ( dont worry, KingoRoot hates, we will replace it with SuperSU later)
  2. First enable Developer Options via Settings> About> tap Software Version about 7 times, until Developer Mode is enabled.
  3. Now go to Settings> Developer Options> enable USB Debugging.
  4. Connect your ZTE Spro 2 to your PC via USB cable, and accept the ADB pairing dialog on the Android screen.
  5. Launch an ADB command window by holding down Shift + Right-click inside the main ADB installation folder and choose ” Open a Command Window Here”.
  6. Now in the ADB terminal, type the following command: restart disemmcwp
  7. Now install the KingoRoot APK file you transferred earlier, and allow it to root your ZTE Spro 2.
  8. If for some reason the KingoRoot process gets stuck around 90%, wait a bit longer, then redo the reboot disemmcwp command in ADB – after rebooting, the device should be rooted, check with a root status app if the KingoRoot process was successful.

Replace KingoRoot with SuperSU

  1. Install the CPU-Z app from Google Play, and use it to check your kernel architecture ( AFAIK, the ZTE Spro 2s Snapdragon 800 processor is ArmV7 architecture, but who knows with so many international variants of devices floating around, its safest to check) .
  2. Once you have confirmed the kernel architecture, download the SuperSU .zip here and save it to your PC, extract all the folders and copy it to your ZTE Spro 2.
  3. Now download a root file explorer (I recommend X-Plore, because it will automatically change the permissions of the files when replacing them, or you will have to manually change the permissions of each file).
