This is the SP Flash Tool release of the

V1.0_20210324 system software

for UMIDIGI BISON 2021 8GB

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.

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.

Hello,
Will there be an SN Writer for IMEI repair for this phone?  Incase someone does the format all when doing a flash?

Using the MD1_DB file from the stock rom, it is giving the error SPMETA_DELL::META_MAUI_DB_INCONSISTENT
I am using SN WRITER TOOL V2.1504.00

Thanks,
Jamtime

I got it all working.  I used the beanpod version of SN Writer here:
https://community.umidigi.com/fo ... &extra=page%3D1

Then I swapped the S5_Pro_kb_0000000000.bin with the one from this stock rom.  You need to delete the S5_Pro_kb_0000000000.bin and then put the stock in the folder and rename it to S5_Pro_kb_0000000000.bin so it uses that one.  This resolves the red water mark for google key failed.

This allowed me to restore IMEI and also to get the google key red watermark resolved.

Also, install this to get sn writer to run.  I had issues and installing all the C++ redistributables fixed that.

If your IMEI is messed up, pull your sim right away.  Otherwise your provider may suspend your sim and you will have to contact them to get it back enabled.
