This is the SP Flash Tool + OTA release of the

V1.1_20170929 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.

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.

• Select 'Reboot system now'. Alternatively you can perform a factory data reset here by choosing 'Wipe data/factory reset'
  

Kind request from users:
Please report any kind of new issues you experience after installing this update only if you've already flashed this ROM with SP Flash Tool in Firmware Upgrade mode. In rare cases a FOTA update can cause more or less serious malfunctions but that means only the update process went wrong, not a badly developed ROM. An updated stock ROM, especially related to the basic functions will not cause any new issues but will solve some of the existing ones.

4) First Grey Button is GPS(OFF) flick to ON - below that you will see Satelite status updates
5) Change GPS MODE to FULL START
6) You should get Prompt from LocationEM2 asking for permissions - grant ALL
7) Go to last Tab - RAW DATA and flick navigation to ON and measurement to ON
- Your GPS should work.

I have two Crystal 4GB and neither one updates correctly.
Both give me error after rebooting in recovery mode and I have to turn them off and on again.
I tried 3 times

I experience the same with my Crystal, even though I don't think it's really a hardware issue. The reason for that is that if you enter engineering mode, you can actually test if you get a gps fix. And that one worked, the gps module sees quite some satellites and calculates the device's position. Somehow the apps can't access this information properly I guess.

There are YouTube videos describing how to fix at least temporarily  these GPS problems with mediatek devices using engineering mode.  It seems to be a common problem with those processors, not limited to the Crystal.  But not easily fixed, sadly.

\n\nI've noticed two other bugs concerning bluetooth: first one is, that even when bluetooth is off, it will automatically turn on when deactivating airplane mode. And the second one, which is really annoying: bluetooth turns off (and hence disconnects)  automatically after a few minutes of playing music or whatever. So, UMIDIGI, please fix that as soon as possible. Thank you.

I tried again installing the update today on my two Crystals 4 Gb. This is all I get. Anyone can help? I am afrid using flash tool as I had problem with a UMI Zero (erased IMEI) using it.
