This is the SP Flash Tool + OTA release of the
V1.2_20181221 system software
for UMIDIGI A3 Pro

Flash tool operation is recommended to experienced users only. If you are not yet an experienced flash tool user, please carefully read the flash tool tutorial before proceeding, and strictly follow each instruction.

Except if an authorized or responsible expert directly asked you to do that,
never format the flash chip of your device or you instantly lose your warranty!

UMIDIGI A3 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.





Changelog:
  • System optimization
  • Minor bug fixes

FOTA version: UMIDIGI_A3_Pro_V1.2_20181221_20181221-1129

SP Flash Tool
Resources:

Flashtool tutorial: http://bit.ly/SPFTguide

Extract the .rar file before use. The scatter file (MT6739_Android_scatter.txt) is inside the extracted folder, together with the other components


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 A3 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 A3 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:

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 the boot selector mode. It needs about 10 seconds or a little bit less if your phone was already powered off.
  • Here you can move with the vol-up button and select an item with vol-down. Select Recovery.
  • Your phone boots into Recovery and you see a lying android figure with an exclamation mark in red triangle on its tummy + '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 both 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 SD card 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.

Dear Umidigi,

I am writing to inform you that some people have bought the A3_Pro_N_V1.1_20190103
These people have bricked their devices.
The reason for that is the confusion between the two different versions of the A3 Pro.
I mean, the firmware A3_Pro_V1.2_20181221 is not compatible with A3_Pro_N_V1.1_20190103

Please post the stock firmware for A3_Pro_N_V1.1_20190103

Best Regards

good after the update of the phone there are applications that begin to use the notch which becomes quite complicated to use because you lose options and there are cubies for the division for example the whatsasp camera and when setting a wallpaper this makes the use of the smartphone sometimes very complicated

Hello,

looks like my Umdigi A3 Pro won't go into deep sleep, main idle frequency is 299Mhz.
In aeroplane mode deep sleep is a bit better, i mean, at least is shown in cpu spy, with normal daily usage i had a 20% deep sleep with a 60% 299 mhz. (didn't used phone so much)
Is there any fix for that?
Thank you
