bencebacsi

This is the SP Flash Tool release of the

V1.0_20220902 system software

for UMIDIGI BISON 2 and BISON 2 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 2 (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.

Changelog:

• Minor bug fixes
  

FOTA version: UMIDIGI_BISON_2_V1.0_20220525_20220902-0003

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 2 (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.

I just purchased the UMIDIGI Bison 2 and I am having issues with viewing the quick setting when the phone is locked. If I swipe down it shows 4 buttons but, it does not allow me to tap on any of the buttons shown nor does it allow me to swipe further down to show additional quick setting buttons.

I can get it to work if I do one of the following:

1.)Enable notifications while the phone is locked AND I receive a notification. I can then expand the notification and swipe down to see the additional quick setting buttons. This works but it's a security concern.

2.)Enable the camera while the phone is locked by double tapping power button. It'll open up the camera and then I can swipe down and see the quick setting buttons. This also works but its a 2 step process.

These are "work arounds" to the problem but, defeats the purpose of having "quick" buttons.

Please advise how I can fix this issue.

Warm Regards,

After I flushed all partitions with Download Only mode, BISON 2 always stop at fastboot mode with "FASTBOOT mode ..." message.
Though I tried this ROM (UMIDIGI_BISON_2_V1-0_20220902) and older ROMS (UMIDIGI_BISON_2_V1-0_20220719, UMIDIGI_BISON_2-E_V1-0_20220815 ), they are same result.
Does someone know how to solve this issue?

I had the same issue... to solve the issue, on the flash tool select "firmware update" instead of download only.

Thank you!!!!!
I applied "Firmware Upgrade" ( w/ UMIDIGI BISON 2 E_V1.0_20220923 ) , and now my BISON2 can boot normally!

Is there an SPFT for Linux?
