In the original post I should have said "SD slot" because that is what I have been using not usb. My bad. I will try what you suggested in a few days. Thank You!
Edit: Sorry to here your Pinebook now has battle scars. Now if I understood you.
1) Computer is unplugged from AC.
2) Remove back cover.
3) Turn off internal eMMc.
4) Have fresh version of operating system of my choice on an installed micro SD card.
5) Turn on computer.
6) Then after ( ? seconds) turn eMMc back on.
7) Reflash "Boot" to first eMMc.
8) Turn off computer and remove micro SD card.
9) Then turn on computer and it should reboot with a working operating system?
