Banana Pi M5 Android Perma Boot

So, I had flashed the Android image onto my Banana Pi, but I can seem to erase it completely. When I boot the Pi, it just shows the Android logo, and doesn’t go anywhere after that. I have tried booting without an SD card, completely erasing it, and flashing a different image to the SD card. I can’t seem to figure it out.
Not sure if this is important, but this is the guide I followed:
