This is the SP Flash Tool release of the
R.E_V1.0_20220524 system software
for UMIDIGI BISON 2021 8GB

European version for EEA countries

This page is updated on 31. May, 2022

Please note, this software release is compatible only with the 2021 edition of UMIDIGI BISON with 8GB RAM


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 2021 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.
You can wireless update to this version from Settings -> System -> Advanced -> System update




Changelog:
  • Minor bug fixes


FOTA version: UMIDIGI_BISON.R.E_V1.0_20210512_20220524-2038

ROM: >>> UMIDIGI_BISON-R-E_V1-0_20220524.rar <<<
Extract the .rar file before use. The scatter file (MT6771_Android_scatter.txt) is inside the extracted folder, together with the other components


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.

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



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, Im new here and, im from Peru.
I have this phone, BISON 2021 8GB RAM - 128GB ROM, with the ROM of the post.

Today, I see the settings apps, and enter into developer options (because need to reduces the duration of animations and transitions) and i found DSU Loader (Dinamyc System Update), then i may choose to install an a generic Android image from Android 13. At the point. i been awaits for download the image and then restart the phone to look how works, but the phone power on with a text message that says:

dm-verification corrupt
Your device is corrupt. It can't be trusted and may not work properly.
press power button to continue.
Or, device will power off in 5s.


Pressing Power button cause my phone starts normally, all my data its intact. But honestly i found anoying to push power button once time i power up the device. (i forgett, this problem is present also in Offline charge mode, the phone start the screen with the battery icon and the error text. If dont press power button the phone not be charged, and the battery being empty).

My question is: ¿Unlocking bootloader and resume the procedure of installs the Generic System Image with DSU can be solve my problem?
In negative case. What files i need to flash in order to rid off the message?

In reading on XDA Forums and other devices like Xiaomi Redmi get this problem too when tried to get ROOT access. By the way, the solution i read consist in:
Download the vbmeta and flash it via fastboot to get rid of the dm-verify.

I don want to re flash the phone, because i have some important things, but it is necessary to do, i really wish if someone knows how to repair my problem instead just get "Start at 0".

Thanks for read, i don´t speak english or chinese but i tried to write all be possible for me. (Cause google translate sometimes change the ideas of the words when i translate it.) Again, thanks if someone can answer me.
