This is the SP Flash Tool + OTA release of the
V1.7_20201222 system software
for UMIDIGI A3 N Android 9.0

Please flash this ROM only if your phone is shipped with Android 9.0 system. This software is NOT directly compatible with Android 8.1 phones!


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:
  • Android Security Patch level updated
  • Minor bug fixes and system improvements

FOTA version: UMIDIGI_A3_N_V1.7_20201222_20201222-1021

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
  • 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

Update file for manual OTA update:
It can update version 20201009 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 the volume-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.
  • Here you can move withthe 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.

Good morning visitors of my page! I did not believe in therapy for a long time, but my psychologist has been nothing but professional, patient and very kind while I start my journey with him. Messaging is very needful as is the video conferencing and my smart therapist been very accommodative to my health issues and time restrictions because of them. I am searching forward to online therapy talk to an online therapist calmerry with my best psychologist and achieving further not so simple goals.

Good morning visitors of my page! I did not believe in therapy...

That's pretty interesting. I'm in over my head because of my problems, but I met you and you recommended such a psychologist. I will definitely make an appointment with him and solve my problems

PRESSRELEASE: “LIFESAVING PWA FOR LGBTQ COMMUNITY, THEAPP.ONE”

When a Gay Couple, David and Charlie went into a bakery in Denver Colorado in 2012 to order a wedding cake, they didn’t know they would end up in a court battle with the baker. In February 2019, Anna and Amanda, a Phoenix AZ Lesbian Couple, tried to arrange a wedding photographer and ended up on the six o’clock news. Sometimes it seems like we are still living in the dark ages. But now there is THEAPP! We have the technology that will allow us to live our lives peacefully and do business within a community that is kind, tolerant and accepting. THEAPP from LGBTQ.one is a revolution in inclusive geo-social commerce. Dedicated to only those businesses that prefer to do business with the LGBTQ community, THEAPP will guide you to the things you want and need day to day. From Cakes to Photographers, from Dress Makers to Hair Stylists, or maybe just a safe and accepting gathering place, whatever locations and/or services you seek, THEAPP will find it for you and assure that it is a friendly and safe experience. LEARN MORE ABOUT THEAPP
YOUTUBE VIDEO: https://www.youtube.com/watch?v=6yNv0OFTJdM
THEAPP from LGBTQ.one has you covered, whatever you are looking for.
Looking for someone? THEAPP has a very special feature. Whether it is a brief chat, a meet up for coffee or a long-term relationship you are looking for, THEAPP has the power to bring together people of like interests in an effective, safe and logical way. Similar to the way an entertainment guide alerts you of nearby businesses and deals offered, even when you are traveling, THEAPP keeps a lookout in a circle around you and notifies you when it detects another LGBTQ THEAPP user nearby. LEARN MORE SERVICES

But, how does THEAPP work? THEAPP works very much like the commercially available “Entertainment Guide” with two very significant differences. The Entertainment Guide serves the general public and does not distinguish between LGBTQ friendly businesses and those that may in fact be hostile towards members of the community. It is important that our members know they are visiting and patronizing merchants who are accepting and ready to provide an enriching and positive experience. The purpose of THEAPP is to provide a safe and friendly experience for both the merchant AND the members they serve. The other distinction between commercially available Entertainment Guides and THEAPP, is those guides charge you to use them, THEAPP is completely FREE to use and is supported by LGBTQ friendly merchants themselves.
