UMIDIGI BISON Pro V1.0_20210818 ROM - SPFT release

bencebacsi

This is the SP Flash Tool release of the

V1.0_20210818 system software

for UMIDIGI BISON Pro

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 Pro 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.

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 Pro 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.

Hi, Thank you for the details and for the ROM files. Unfortunately, flashing back the device with the original files didn't help.

My phone constantly restarts/shut down when I make a call or decide to open an app etc. So I can make a quick call for example and it will all work but the next call I dial the moment I press the green button and the phone restarts.

Is there anything you can advise me that will help. Umidigi have refused to deal with the phone as faulty although it is still in warranty - it is 4 months old but totally unusable to me. So I'll appreciate any help - I believe it is a hardware issue but...

Thanks anyway
