This is the SP Flash Tool release of the

V1.0_20210621 system software

for UMIDIGI BISON 2021 6GB

Please note, this software release is compatible only with the 2021 edition of UMIDIGI BISON with 6GB 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.

Changelog:

• Optimized WiFi connection
• Allow uninstalling the Zello app
• Screen multi touch performance optimized
• Other minor bug fixes and system improvement

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_v5.2136.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 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.

Hi calm down.
If your device is in BOOT loop, then you have HW issue probably on main PCB (probably your memory on PCB is dead)
You Can't reapir by rewrite FW.

Hi, in older topic UMIDIGI user write this, I'll hope that help you.
::::::::::::::::::::::::::::::::::
The E (EEA) version contains only different google certificates but it's fully compatible with the non-EEA version released for the same hardware. Retailers are allowed to sell phones in the EEA region only with EEA software installed on them but as an end-user, you may use any compatible software. A BISON 2020 can not boot up (you get a boot loop) with a BISON 2021 software installed on it and vice versa.

BISON = 2020 version, Android 10
BISON_1 = 2021 version with different motherboard, Android 10
BISON_6R = The Android 11 upgrade of the BISON_1

Thank you my dear for your attention and response.
My question remains: How to know, on the device, which version is it?The device does not turn on and remains in a loop. From the serial number or on the box, can you tell?
