bencebacsi

This is the SP Flash Tool + OTA release of the

V1.0_20221018 system software

for UMIDIGI BISON

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 BISON 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:

• Android security patch level updated to October, 2022
• Minor bug fixes
  

Please note, the UMIDIGI BISON 2020 will not receive Android version upgrade, it remains on Android 10.

FOTA version: UMIDIGI_BISON_V1.0_20221018

ROM: >>> UMIDIGI_BISON_V1-0_20221018.rar <<<

Extract the .rar file before use. The scatter file (MT6771_Android_scatter.txt) is inside the extracted folder, together with the other components.

SPFT: SP_Flash_Tool_v5.2216.rar

VCOM driver: Windows 10 can automatically install it. Please make sure that your Windows is logged in with administrator rights and your computer has a working internet connection when first time connecting your phone.

Here's an optional solution to start the flashing process on your UMIDIGI BISON if the standard method doesn't work.

It's especially useful if your phone is bricked or is stuck in bootloop

1. Connect your phone to USB.

2. Start the flashing process with the Download button in the flasher app.

3. Press and hold 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.

If you accidentally formatted the flash chip of your phone, visit the following thread: A7, A7S, A7 Pro, A9 Pro, BISON: Repair IMEIs, MEID and Google certificate

OTA (recovery) update

Manual (local) OTA update method instructions

• Copy the downloaded .zip file to the internal storage of your phone
• Go to Settings → 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:

>>> UMIDIGI_BISON_V1.0_20221018_update.zip <<<

It can update version 20220711 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. As soon as the boot screen flashes up, release the power button and keep only the vol-up button pressed.
• In a few seconds, your phone boots into Recovery and you see a lying android figure with an exclamation mark in red triangle on its tummy, and ‘No command’. Release the vol-up button.
• Press and hold the power and vol-up buttons (in this order) together, then release them (first the vol-up button) 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 update process will start and needs a few minutes to be finished.
• After a successful installation, you can read the ''Install from SD card complete.'' message and the recovery 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.

The main issue of my phone is this. "The screen will suddenly freeze, however if i touch some command like delete on LONG TAP, it will work. (In long TAP). But the screen is not working if i touch it basically. Somehow the basic solution is lock the screen and unlock, the frozen screen will be okay again. Still, after some time it will come again."

Is the system has the problem? Or the touch screen? I plan to replace my touch screen, however i doubted it. What if the problem is still there?

Thank you

Tenho um problema há anos, desde 2021. O que acontece é que o celular reinicia do nada, quando estou utilizando e não sei quando ele fará isso, só sei que impede o seu funcionamento. Já testei todas essas versões de software e não corrige esse problema. Já tentei ROMS de outros modelos, mas elas não iniciam. Tá complicado essa vida. Espero que o suporte corrija esse problema, porque eu não sou o único.

Verifique como ele se comporta na versão européia:

Se o problema não desaparecer, não é culpa do firmware, mas do equipamento.
