This is the issue. I think I may have read your jumper pin incorrectly for the PICO board jumpers. I thought the header pins were switched around in the photo. I did not know the header pins were situated where they were in the photo for eMMC Boot Mode. I got the USB Boot Mode done correctly. There was not a way to goof that one up.
Here is the terminal issue when attempting a DFU command:
torx@forket:~/u-boot$ sudo dfu-util -D SPL -a spl

dfu-util: Invalid DFU suffix signature
dfu-util: A valid DFU suffix will be required in a future dfu-util release!!!
dfu-util: No DFU capable USB device available
I can interpret what I did earlier if that makes any difference. I know exactly what happened now, i.e. incorrect jumper positions.
