This is the SP Flash Tool + OTA release of the

V1.4_20200630 system software

for UMIDIGI A3S

European version for EEA countries

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 A3S 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:

• Minor bug fixes and system optimization
  

FOTA version: UMIDIGI_A3S.E_V1.4_20200630_20200630-1220

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.

You need a microSD card (with at least 4GB capacity) installed in your phone!

• 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.

Hi Ben,

I would like to set one sip account to use with built-in sip stack. But I can't find sip accounts settings. Ususally they are on phone settings, but there is nothing there. Why? How can I do this?
I know I can use one of voip apps available on playstore, but why should I install one more app if android has it's own sip stack that usually gives good quality connections?
Please say sometthing about this. Thanks.

Buenos dias, mi nieto le ingreso un patron y se le olvido a un UMIDIGI A3S, asi como tambien se le olvido el correo y la clave ingresada de la cuenta Google, se le hizo un formateo para restablecer el celular de fabrica pero el patron y la cuenta google aun estaban presentes, se recurrio a un tecnico para q eliminara la cuenta y el patron y segun inmformacion del mismo realizo un porceso llamado FRP, efectivamente elimino la cuenta y el patron, pero ahora el celular no levanta señal y tampoco aparece la opcion de huella Dactilar. Tamben nos informó q el revisando el IMEI del equipo las paginas de informacion arrojan que es un UMIDIGI A3, y no un A3S como deberia ser.
Que solución recomiendan para solventar dicho inconveniente? agradecido por su pronta respuesta.
