bencebacsi

This is the SP Flash Tool release of the

V1.0_20170728 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:

First (MP) release for manufacturing

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.

Hi,
I'm sorry but it's not up to us. You can root a phone via TWRP but TWRP recoveries are created by users, not by the manufacturer. TWRP is still not available for Z1, Z1 Pro and C Note 2.

they support volte or not? what about band 40 in india?

Will this come with bootloader unlocking for custom ROMs?I don't expect much as it's a MediaTek device, but options would be nice in the future for small mods and improvements.


I will try to make a TWRP recovery for this device, but I can't make promises as it will be my first attempt at making a recovery.
