This is the SP Flash Tool + OTA release of the
V1.4_20190321 system software
for UMIDIGI A3

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 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:
  • Minor bug fixes
  • System optimization

FOTA version: UMIDIGI_A3_V1.4_20190321_20190321-1157

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 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 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

  • 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

Update file for manual OTA update:
It can update version 20181220 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.zipfile to your SD card.
  • Press and hold thevolume-up and power buttons together until your phone restarts in the bootselector mode. It needs about 10 seconds or a little bit less if your phone wasalready powered off.

  • Your phone boots intoRecovery and you see a lying android figure with an exclamation mark in redtriangle on its tummy + 'No command'.
  • Press and hold thepower and vol-up buttons (in this order) together, then release them to callthe recovery menu. Now you can move with both volume buttons, and select anitem with the power button.
  • Move to ‘Apply updatefrom SD card’ and select it.
  • On the next screenbrows for the update file and select it. The updating process will start andneeds a few minutes to be finished.
  • After a succcessfulinstallation you can read the ''Install from SD card complete.'' message andthe receovery menu is available again.
  • Select 'Reboot systemnow'. Alternatively you can perform a factory data reset here by choosing 'Wipedata/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.

It is the number of the technical standard conformity certificate about the telecommunications of Japan, but there is that A3 and A3pro numbers are different in the net.
・ A3 Pro ...... 205-190376
・ A3 ............ 205-190375
Actually, A3 too
205-190376
Is it displayed? Did you make a mistake when listing this in the farm?
I would like you to list the FCC and CE numbers if you mention it
I want you to reply and get a new farm.

With the battery fully drained, press the download button on the tool and wait for it to connect to the terminal where the battery is drained and then turn on the power
The tool should enter download mode just before entering the loop when it is charged and turned on

After a firmware update on 2nd March, a bootloop has occured on my Umidigi A3.

The Costumer Support advised me to try a factory reset and wipe cache partition from recovery mode but this procedure didn't solved the problem.

In addition they raccomended to reinstall the firmware from official site.
Does the procedure described in this thread concern this?

Thanks

Hi, I flashed the rom with the sp flash tool. My A3 passed boot loop, However both IMEI were lost. Is there a way to restore IMEI? The SN writer tool failed.

hello all!

unfortunately...same here.. did an SP flash update of 1.3 no IMEI would load.. went up to 1.4 via SP flash again.. no IMEI.

i did get this resolved by going back to V1.2...0427. after SP finished, SIM cards picked up right at boot - just like normal. is there going to be a fix tor this soon? i'd like to take advantage of any bug fixes and improvements

i have not had the time, or wanted to see, if doing a sequential update from recovery would solve this. i only did the SP flash for my updates.

cheers!
