This is the SP Flash Tool release of the V3.01_20170228 (Android 6.0) firmware for UMIDIGI Z PRO
Flash tool operation is recommended for experienced users only. Do not use it if you cannot understand the whole process!
UMIDIGI Z PRO receives all updates automatically via FOTA method. You need this tool only in case of emergency (if you’ve bricked your phone), if you want to apply a clean install or if you want to clear all root access and custom recovery to make your phone able to receive FOTA updates again.
If you are updating an earlier version, it is recommended to flash this ROM as ‘Firmware Upgrade’!
Improved fingerprint sensor performance
GPS driver updated and optimized

Here’s an optional solution to start the flashing process on your UMIDIGI Z PRO if the standard method doesn’t work.
It’s especially useful if your phone is bricked or is stuck in bootloop
1. Connect your UMIDIGI Z PRO to USB.
2. Start the flashing process with the Download button in the flasher app.
3. Press and keep pressed the power button of your phone until the flashing process starts (red bar appears at the bottom of the app window), then release it. In this process you have to keep the power button pressed for about 10 seconds.
4. Wait until the flashing process finishes.
