Allwinner A133 firmware install

Step 1: Install Drivers & PhoenixSuit

  1. Disable driver signature enforcement on Windows 10/11:
    • Restart your PC → Press Shift while clicking Restart → Troubleshoot → Advanced Options → Startup Settings → Restart → Press 7 or F7 for “Disable driver signature enforcement”.
  2. Install PhoenixSuit:
    • Run the installer as Administrator.
    • During installation, allow it to install the Allwinner USB drivers.
  3. Verify driver installation:
    • Connect your device (powered off) to the PC with the USB-A cable.
    • Open Device Manager → Look for “USB Device (VID_1f3a)” or “Allwinner USB FEL Device” under Universal Serial Bus devices. If you see an unknown device, manually install the driver from the PhoenixSuit Drivers folder.

Using LiveSuit for A133

LiveSuit is an older tool but still works. The process is nearly identical but less robust. Avoid it unless PhoenixSuit consistently fails. If you must:

  1. Install LiveSuit and its drivers.
  2. Load the .img file.
  3. Enter FEL mode and click "Upgrade" – the UI is minimal but functional.

3. Make a Full Backup

Once the device is stable, use PhoenixSuit’s "Read" function (if available) to read back the full flash. Save this as your personal recovery image. allwinner a133 firmware install

  3. Allwinner USB Drivers: These allow Windows to talk to the A133 in FEL mode.
  4. A small tool (optional): zadig for driver troubleshooting.
