I give up! Today I tried two last things:
1. I booted from my Ubuntu 20.04 MicroSD card and wiped the EMMC completely in Gparted before DDing the .img file over with the exact same command you used except using mmcblk2 because that was where my EMMC was mounted. I took a deep breath, powered off, and surprise! yellow light and no display output at all.
2. I plugged the EMMC into my computer and wiped it. This time, though, Gparted gave me an error about the GPT not being right, so I clicked fix and my EMMC's capacity jumped from 58 GB to 62 (?). Then I created an ext4 filesystem on it before using Etcher to write the image to the EMMC. I turned my Pinebook Pro on and...no luck. Strangely, I had my Ubuntu 20.04 MicroSD card in part of the time, but even with it in, I never got past the yellow light. Even if the image on the EMMC is somehow corrupt, it should at least boot to SD, right?
Thank you SOOOO much @Syonyk for troubleshooting with me, but without a UART cable, I think running the image from my SD card is the closest I can get to running this image on my Pinebook Pro. Maybe later...
