Step 5: Boot Your Device into Fastboot Mode

To proceed with downgrading, we need to boot your device into Fastboot mode. Here’s how:

  1. Open a command prompt or terminal window on your computer.
    • If you’re using Windows, press Win + R, type “cmd”, and hit Enter.
    • If you’re using macOS or Linux, open the Terminal application.
  2. Navigate to the folder where you extracted the Android SDK Platform Tools.
  3. Type the following command to boot your device into Fastboot mode:
  4. adb reboot bootloader

Step 6: Flash Android 11 Firmware

Now, it’s time to flash the Android 11 firmware onto your device:

  1. Locate the downloaded Android 11 firmware file on your computer.
  2. Copy the firmware file to the folder where you extracted the Android SDK Platform Tools.
  3. In the command prompt or terminal window, type the following command to flash the firmware:
  4. fastboot flash system [firmware-file-name]

Step 7: Reboot Your Device

Congratulations! You have successfully downgraded your Android device from version 12 to 11. To complete the process, let’s reboot your device:
