bencebacsi

This is the SP Flash Tool release of the

V1.0_20170811 system software

for UMIDIGI Crystal 2GB

This ROM is only for the 2GB version with MT6737T 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.

Changelog:

• Optimized battery consumption
• Minor bug fixes

Extract the .rar file before use. The scatter file (MT6737T_Android_scatter.txt) is inside the extracted folder, together with the other components

SPFT: SP_Flash_Tool_v5.1728.rar

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.

Hello

From  September 29th is available an OTA update, but it fails when trying to install it (error message in the maintenance mode).

What "minor fixes" are solved?

If I have success in making a TWRP, I will post a guide of course.

Don't worry, the first ROM will be available for download before the first handsets get delivered. A successful rooting has a little chance.

Are you suggesting that rooting the phone would be difficult?

Yes, except if someone creates a TWRP recovery. To break the running Android system is almost impossible since Marshmallow, usually it can be done from recovery only.

Then I will look into doing a TWRP project. Miss the old days of easy root.

If you will root 4gb version successfully could you post such information (or even twrp binaries) here or in 4gb version thread. I will be very grateful.
