Dennis, thanks for explaining an option. I have the original image on mSD. Can that be used to recreate (copy or build) the proper partition table on the eMMC? How is that done? Maybe the data will not be overwritten. If it does not work, I will lose all data anyway when reflash all.
Based on the above dd command (I ran by mistake), maybe from mSD run: sudo mount /dev/mmcblk1 Then remove mSD and reboot. But I don't know if I have all the correct parameters such as block size or count or destination. Thanks for any help.
