Moreover, flashing with SPFT is the only option to repair (replace) damaged system software.

You can wireless update to this version from Settings -> System -> Advanced -> System update

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 2021 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.

Hello, greetings... my phone is a BISON 2021

My problem is that I can't update the rom since I have the problem that says "dm-verify corruption" for which as soon as I connect the phone the message appears and it immediately turns off and does not give time for it to recognize the phone for the download getting said message "ERROR: STATUS_STOR_LIFE_EXHAUST (0xC003001D) The storage in your device or close this feature by the option (Storage Life Cycle Check) in the option dialog. [HINT]:", looking in the forum I found several alternatives like trying use the power button and volume up at the same time after downloading but this method has not worked for me either, please I need help to solve this problem.

I am doing this because, as I mentioned before, I have the dm-verify corruption problem and when I pressed the power button before 5 seconds before, it turned me on normally, but now when I do the same I get a message that says "Red State your device has failed verification may not work properly.
Please download boot image with correct signature or disable verified boot"
