bencebacsi

This is the SP Flash Tool release of the

V1.0_20220714 system software

for UMIDIGI BISON GT2 5G and GT2 Pro 5G

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 GT2 5G and GT2 Pro 5G receive 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:

• Upgrade to Android 12 system
  

Warning! Once you upgraded to Android 12, you can downgrade to Android 11 only by flashing in Firmware Upgrade mode (your user data will be erased), otherwise your phone will not be able to boot up.

FOTA version:

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 GT2 5G or GT2 Pro 5G 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.



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.

Update works just fine, I have not encountered any issue, it did fix the issue with the night mode photography from the main camera app, thanks!

Привет. Телефон Umidigi Bison GT 2 pro 5 г. После обновления до Android 12 в режиме модема и точки доступа нет возможности выбрать сеть 2,4 Ghz для раздачи интернета на другие устройства. А моя магнитола в машине осталась без интернета.

Hello. Umidigi Bison  Gt 2 pro 5 g phone. After updating to Android 12 in modem mode and access point, it is not possible to select a 2.4 Ghz network for distributing the Internet to other devices. And my radio in the car was left without the Internet.

Same happened to me, easy fix was to go into quickstep app info quickly and clear app storage then restart. Worst case factory reset will also fix the issue.

Everything was working fine for me till today. Suddenly the smart keys are not working anymore and the 3 button navigation keys don't show if an app is running full screen such as games or YouTube. What's the fix for that?
