It may be the uboot on the eMMC that is unable to boot the SD card. I would try temporarily removing the eMMC from the the board inside (or was there a switch to disable it?) and see if the SD card is booted.
There was a way to set the Pinebook Pro into eMMC recovery mode where you could flash it over the USB-C.
Or you can overwrite the uboot on the eMMC with the one on the SD card (BE VERY CAREFUL as it can make your computer unbootable at all).
Or you can order the USB to eMMC adapter from the Pine64 store and flash it from another computer.
But start with disabling the eMMC to see if you can boot from SD.
