How to Bypass DA Authentication, Authentication File, and Secure Boot for SP Flash Tool

Hi everyone!

Today, I’ll guide you through bypassing DA authentication, authentication files, and secure boot in SP Flash Tool using a utility called Bypass Utility. This tool, developed by a GitHub nutcase, is a helpful workaround for bypassing these protections.


Steps to Bypass Authentication

  1. Download the Tool

    • Get Bypass Utility from this link and extract it to C:/Program Files.
  2. Install USB Drivers

  3. Install Required Dependencies

    • Open your terminal and run the following command:
      pip install pyusb json5
      
  4. Run the Tool

    • Navigate to the extracted Bypass Utility folder. Open a terminal as administrator in the folder or use the cd command to navigate there.
    • Launch the utility by running:
      python main.py
      
  5. Connect Your Device

    • While holding the back button, plug in your device to begin the process.
  6. Explore Options

    • To view all available commands and features, use:
      python main.py -h
      

Important Notes

  • Device Compatibility:
    Currently, the tool does not support newer F21 Pro models. I’m actively exploring a solution, but for now, it works with most other devices.

  • Caution:
    Avoid using this tool with official or “kosher” ROMs. I am not responsible for any issues caused by using this tool—proceed at your own risk!
