OpenMV-H7 R1: "No OpenMV Cams found!"

I took a note from this post and used STM32CubeProgrammer to flash OPENMV4/bootloader.bin to 0x8000000 and OPENMV4/firmware.bin to 0x8040000. That all went fine. I unplugged the board and plugged it back in. Now the LED is blinking green with the occasional white flash sprinkled in. I still get “No OpenMV Cams found!” when I try to connect through the IDE. I went through the “it’s bricked” dialog again, and unplugged and replugged in the board when prompted. I’m now faced with the forever progress bar, again.
