UMIDIGI Crystal V1.1_20170929 ROM - SPFT + OTA release

[Copy link]
Post time 2017-10-12 06:29:11 | Show all posts |Read mode
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.






Changelog:
Not provided


--------------------------------------------------------------------------------
SP Flash Tool
Resources:

Flashtool tutorials: UMI Forum or androidxda guide or YouTube guide (you can google a lot of other solutions and guides)

Extract the .rar file before use. The scatter file (MT6750T_Android_scatter.txt) is inside the extracted folder, together with the other components


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.

--------------------------------------------------------------------------------
OTA (recovery) update
Manual (local) OTA update method instructions
  • Copy the downloaded .zip file to either the internal memory or the SD card of your phone
  • Go to Settings --> About phone --> Wireless update
  • Tap the 3-dot menu button at the top right corner and select Local updates
  • Brows for the ...update.zip file and select it
  • Tap Install now, comfirm the process with OK and wait until the process will be finished

Update file for manual OTA update: >>>>> UMIDIGI_Crystal_V1.1_20170929_update.zip <<<<< It can update version 170903 only

Optional method (in case if the manual OTA update gets stuck): Install from recovery
You need a microSD card (with at least 4GB capacity) installed in your phone!
  • Copy the ...update.zip file to your SD card
  • Press and hold the volume-up and power buttons together until your phone restarts in recovery mode. It needs about 10 seconds or a little bit less if your phone was already powered off.
  • Here you can see a lying android figure with an exclamation mark in red triangle on its tummy and ''No command''.
  • Press and hold the power and vol-up buttons (in this order) together, then release them to call the recovery menu. Now you can move with the volume buttons and select an item with the power button.
  • Move to ‘Apply update from SD card’ and select it.
  • On the next screen brows for the update file and select it. The updating process will start and needs a few minutes to be finished.
  • After a succcessful installation you can read the ''Install from sdcard complete'' message and the receovery menu is available again.
  • 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.

Edited by ChangeToTower at 2017-10-14 01:08 \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.
