bencebacsi

This is the SP Flash Tool + OTA release of the

V1.0_20201223 system software

for UMIDIGI BISON

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 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:

• WiFi connection optimized
• Gyroscope issue in VR games fixed
• Flashlight delay in camera fixed
• Other minor bug fixes and system optimization

ROM: >>> UMIDIGI_BISON_V1-0_20201223.rar <<<

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 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 Pro, BISON: Repair IMEIs, MEID and Google certificate

OTA (recovery) update

Manual (local) OTA update method instructions

• Copy the downloaded .zip file to the internal storage of your phone
• Go to Settings → About phone → Wireless update
• Tap the 3-dot menu button in the top right corner and select Local Updates
• Brows for the ...update.zip file and select it
• Select INSTALL NOW, then OK in the Warning window. Your phone reboots into recovery, the update gets installed, then your phone boots into Android. Your updated system is ready to use.
  

Update file for manual OTA update:

>>> UMIDIGI_BISON_V1.0_20201223_update.zip <<<

It can update version 20201124 only

Optional method (in case if the manual OTA update gets stuck): Install from recovery

You need a microSD card (with at least 4GB capacity) installed in your phone!

• Copy the ...update.zip file to your SD card.
• Press and hold the volume-up and power buttons together until your phone boots into Recovery and you see a lying android figure with an exclamation mark in red triangle on its tummy + 'No command'..
• Press and hold the power and vol-up buttons (in this order) together, then release them to call the recovery menu. Now you can move with both volume buttons, and select an item with the power button.
• Move to ‘Apply update from SD card’ and select it.
• On the next screen brows for the update file and select it. The update process will start and needs a few minutes to be finished.
• After a succcessful installation, you can read the ''Install from SD card complete.'' message and the recovery menu is available again.
• Select 'Reboot system now'. Alternatively you can perform a factory data reset here by choosing 'Wipe data/factory reset'
  

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 made an update via SPFT. Microphone problem not resolved

My BISON updated via OTA. I got some problems.

1. Almost, the camera can not run normally in device sleep with start with a double-tap power button.
2. In speaker voice call mode, the volume cannot control. Probably it is fixed at the max.

Does anyone know how to fix problems?

Hi Support,
I have an issue with my BISON and the Youtube App.

I have found that when Advertisements are being displayed my video becomes pixelated and sometimes video playback seems to be either lagging or missing frames. I'm on this current Android Build

Regards,
Dennis

Not sure if anyone else has this problem, but GPS on my Bison is no longer working. Any solutions? I even tried to use SP Flash, didn't make a difference.

estou perdendo minha paciencia, tudo que pediram aqui pra fazer eu fiz. Exatamente tudo, tentei recovery mode por SD CARD, por armazenamento interno, app flash, TUDO, nada resolveu, tentei todas versões disponíveis, nenhuma delas instalou, fala "bad file" quando tento realizar via SD CARD, ou da "error" quando tento por armazenamento interno, e quando tento pelo FLASH ele da erro de "STATUS_DEVICE_CTRL_EXCEPTION" ou "FAiled to get PMT info". não tenho onde mais recorrer. O SUPORTE me mandou procurar a loja que me vender e resolver com eles, isso não resolve meu problema sra. FABRICANTE UMIDIGI.
Meu problema iniciou com o microfone não funcionando apenas em chamadas de video, pediram pra eu instalar a versão 20210126 ultima e fresquinha, e também foi a unica versão que eu consegui instalar via flash app, depois de instalada eu perdi o microfone pra tudo, não consigo fazer chamadas de simcard, nem de whatsapp, nem mandar audio, nem PTT, nem absolutamente nada. Quero voltar outras versões pra tentar resolver o problema.

i'm losing my patience, everything i asked for here i did. Exactly everything, I tried recovery mode by SD CARD, by internal storage, flash app, EVERYTHING, nothing resolved, I tried all available versions, none of them installed, say "bad file" when I try to do it via SD CARD, or "error" when I try for internal storage, and when I try to FLASH it gives an error of "STATUS_DEVICE_CTRL_EXCEPTION" or "FAiled to get PMT info". I have nowhere else to turn. SUPPORT sent me to look for the store that sells me and to solve with them, that does not solve my problem Mrs. UMIDIGI MANUFACTURER.
My problem started with the microphone not working only on video calls, I was asked to install the latest and fresh version 20210126, and it was also the only version I was able to install via the flash app, once installed I lost the microphone for everything, no I can make simcard calls, whatsapp messages, send audio, PTT, or absolutely nothing. I want to go back to other versions to try to solve the problem.
