bencebacsi

This is the SP Flash Tool release of the

V1.0_20210813 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:

• Flash light low brightness issue while recording video fixed
• Other minor bugs fixes and system optimization
  

FOTA version: UMIDIGI_BISON.6R_V1.0_20210428_20210813-1146

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.

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.

I am wanting to change from 20210406 version with Android 10 to this one 20210813 with Android 11.

I would like to know if making such a big change from Android 10 to 11, if I should instead choose "Firmware Upgrade" mode for SP Flash instead of "Download Only"?

Thank you

Hi, I updated without problem by spflahstool to the latest version published which is the one for the month of August, but from my point of view the one for the month of June is better optimized

Amigo, me paso lo mismo. debes hacer tu respectivo respaldo de datos, luego en configuración llevar el celular a modo de fabrica y luego hacer la actualización de 55MB. es todo.

hi ... someone knows how I can fix the signal band of the chips. since my phone does not recognize the chips. It only recognizes a single operator and in 3g, with the 4g it does not make or receive calls.

The OTA update to Android 11 worked fine for several days for my 2021 6G Bison then on a restart seemed to go into a boot loop. In trying to flash the stock rom  I accidentally formatted the entire phone. What I need to know is the order needed to flash everything or if it doesn't matter. At present it is an expensive paperweight. Love the phone and would like to get it working again. I believe that I've downloaded the tools required to do this other than the preload binaries. Any help would be appreciated.

The phone works very well, the detail is in the battery, it discharges very quickly, we occupy optimizing the use of the battery and it would be a perfect phone, any update to correct it?,
