Prerequisites
Before you start the firmware installation process, please ensure you have prepared the following items and completed these essential steps:
- Backup IMEI Numbers: It’s wise to note down and securely save your Umidigi Bison 2 Pro’s IMEI numbers before flashing begins.
- Remove Google Accounts: Sign out of all Google accounts currently logged into your phone. This helps prevent potential FRP lock issues after the flash.
- Backup Your Data: Flashing firmware will erase all user data. Therefore, create a thorough backup of important files, including accounts, contacts, music, videos, and photos.
- Charge Your Device: Ensure your phone’s battery is charged to at least 50% to avoid interruptions during the process.
- USB Cable & PC: Have a reliable USB data cable and a Windows computer with functioning USB ports ready.
- Install Necessary Drivers: Download and properly install these drivers on your PC:
- VCOM Drivers (Essential for MediaTek devices)
- Umidigi USB Drivers (Specific device drivers)
- Reiterate Data Backup: Always double-check that your important data is backed up elsewhere to prevent accidental loss during the flashing procedure.
How to Install Firmware on Umidigi Bison 2 Pro
The recommended method for flashing this firmware is using the SP Flash Tool, potentially requiring a secure boot Download Agent (DA) file for devices with SLA/DAA protection. If a specific DA file for this model isn’t readily available, an alternative is to use the MTK Client tool. Here are the step-by-step instructions using the standard MediaTek (MTK) SP Flash Tool:
- Download and Extract Firmware:
- Download the correct firmware package for your Bison 2 Pro from the links above.
- Extract the contents of the downloaded ZIP file into a clearly named folder on your computer.
- Install Required Drivers:
- Confirm that you were able to successfully install the VCOM Drivers and the Umidigi USB Drivers on your PC before proceeding.
- Launch SP Flash Tool: Open the SP Flash Tool application on your computer. If you haven’t installed it yet, download the latest version for your operating system: SP Flash Tool for Windows or SP Flash Tool for Linux. You can also find our complete step-by-step SP Flash Tool flashing guide here.
- Load the Scatter File:
- Inside the SP Flash Tool, click the “Scatter-loading” button.
- Browse to the folder where you extracted the firmware files and select the file named “MTxxxx_Android_scatter.txt” (the exact name might vary slightly).
- Connect Your Device:
- Completely power off your Umidigi Bison 2 Pro.
- Connect your phone to the PC using the USB cable while it’s off. The SP Flash Tool should detect the device automatically (you might hear a connection sound).
- Start the Flashing Process:
- Ensure the flashing mode is set to “Download Only” (unless specific instructions state otherwise).
- Click the large “Download” button in the SP Flash Tool to begin installing the firmware.
- Crucially, do not disconnect the device or interrupt the process until it shows a success message (often a green checkmark).
- Wait for Completion and Reboot:
- Once the flashing process finishes successfully, disconnect your device from the PC.
- Power on your Umidigi Bison 2 Pro. The first boot after flashing might take longer than usual, so be patient while it initializes the new system files.
Missing IMEI or Corrupt Baseband After Flashing?
In some cases, flashing firmware might lead to issues like a missing IMEI number or a corrupted baseband, preventing network connectivity. If this happens, you can usually fix it by following these steps:
- Install Correct Drivers: First, double-check that the necessary MediaTek (MTK) drivers, particularly VCOM drivers, are properly installed on your computer.
- Use an IMEI Repair Tool: Specialized tools are available for restoring IMEI numbers on MediaTek devices. Popular options include the SN Write Tool or Maui Meta for MediaTek. You can learn more about using the SN Write Tool or Maui Meta tool through tutorials.
- Run the Repair Process:
- Connect your device to the computer (it might need to be in a specific mode, like Meta Mode for Maui Meta).
- Launch the chosen tool and follow its interface to input your phone’s original IMEI numbers (usually found on the box or device back) for both SIM slots if applicable.
- Initiate the repair process by clicking “Start” or “Write IMEI”.
- Restart Your Device: After the tool confirms the process is complete, disconnect and reboot your phone. Check if the IMEI is restored by dialing *#06# in the phone app.

Common Issues and Solutions During Flashing
While flashing is generally straightforward, you might encounter some common hurdles. Here are quick solutions for frequent problems:
- Device Not Recognized by PC:
- This often points to driver issues. Ensure both VCOM and Umidigi USB drivers are correctly installed. Reinstall them if necessary.
- Also, try using a different USB cable (preferably the original one) or connect to a different USB port on your computer (avoid hubs).
- Boot Loop After Flashing:
- If your device gets stuck restarting after flashing, boot it into recovery mode (usually by holding Power + Volume Up).
- Once in recovery, navigate using volume keys and select “Wipe data/factory reset” using the power button. Then reboot. Note this erases data.
- Flashing Errors in SP Flash Tool:
- Error messages can occur if the wrong file is selected. Double-check that you loaded the correct scatter file corresponding to the downloaded Umidigi Bison 2 Pro firmware.
- Ensure you are using a compatible version of the SP Flash Tool and that the firmware file wasn’t corrupted during download. Try downloading again if unsure.
