This is the SP Flash Tool pre-release of the

V1.1_20170824 system software

for UMIDIGI Crystal 4GB

This ROM is only for the 4GB version with MT6750T SoC

Flash tool operation is recommended for experienced users only. Do not use it if you cannot understand the whole process!

UMIDIGI Crystal 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.

VCOM driver: Windows 10 already automatically can install it or you can use this: MTK_Driver_Auto_Installer_SP_Drivers_20160804.exe

Here's an optional solution to start the flashing process on your UMIDIGI Crystal 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 Crystal 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.

Is VOLTE functional in this build, am actually thinking of reverting back to the build that has Volte working, can anyone confirm?
