This is the SP Flash Tool + OTA release of the
V1.0_20180914 system software
for UMIDIGI Z2 Pro

Flash tool operation is recommended to experienced users only. Do not use it if you cannot understand the whole process!
UMIDIGI Z2 Pro 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. Moreover, flashing with SPFT is the only option to repair (replace) damaged system software.





Changelog:
  • Startup security code check bug fixed!
  • Low power shutdown voltage changed to 3.45V
  • Settings --> Display --> Proximity sensor calibration removed
  • Improved WiFi stability
  • Improved GPS signal quality
  • Updated camera effects
  • Other minor bug fixes and system UI changes


The system will show UMIDIGI_Z2_PRO_V1.0_20180823 as Build number after this update but the real version is V1.0_20180914

--------------------------------------------------------------------------------

SP Flash Tool
Resources:


Extract the .rar file before use. The scatter file (MT6771_Android_scatter.txt) is inside the extracted folder, together with the other components
FOTA version: UMIDIGI_Z2_PRO_V1.0_20180823_20180913-1920


VCOM driver: Windows 10 already automatically can install it (if your computer is connected to the internet) 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 Z2 Pro 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 Z2 Pro 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 the internal storage of your phone
  • Go to Settings --> System --> About phone --> Wireless update
  • Tap the 3-dot menu button in the top right corner and select Local Updates
  • Brows for the ...update.zip file and select it
  • Select INSTALL NOW, then OK in the Warning window. Your phone reboots into recovery, the update gets installed, then your phone boots into Android. Your updated system is ready to use.


Update file for manual OTA update:
It can update version 20180823_20180823 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 (the boot screen is displayed), then immeduately release the power button and keep only the vol-up button pressed until your phone boots into recovery. 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 first the vol-up button 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.

So....you can't confirm when it will be released and only experienced users can try this upgrade.

I don't know what you guys doing. People who are buying your phone are not ready for all these flash rom stuffs.
I have to learn all of those to get a fixed phone?

Dear Users,

This update is not yet available via OTA and I have no information when it will be. Since it's an urgent update with very important bug fixes, I recommend you to flash it with SPFT. You can flash it without the userdata partition to maintain your user data.
EDIT: update file for manual OTA update has been added.

Yours sincerely,
Ben

Why the option "proximity sensor calibration" has been removed ?
Has the default been solved or will it still be impossible to hangout a call ?

Carefully read the flash tool tutorial and you'll be experienced. special skills are not needed, just a well working Windows 10 PC. The OTA update is going to be released in a few days, I just don't know when exactly. So as an instant solution, you can flash the update with SPFT. It's even faster then an OTA update.

No need to remove your existing security methods before installing this update.

It was ineffective, the proximity sensor can auto-calibrate itself.
