Okay, yeah -- an ODROID C2 -- that's the model that I have, and I'm pretty confident that it DOESN'T have UEFI.
Apparently it has some kind of binary-only bootloader stuff that you ran afoul of in some unclear-from-your-postings way.
I can understand being opposed to this in a matter-of-principle kind of way -- those of us who are should consider supporting the FSF and/or projects like EOMA68 (https://www.crowdsupply.com/eoma68 )
However, there's a number of practical workarounds that are only mildly annoyingly convoluted that enable you to run any kernel you want (or any kernel that has sufficient driver support).
Also, it's my understanding that this problem exists with nearly all of these pocket-computer/fruit-pi devices to some degree or other -- to the point that it's a shorter list of the devices that don't have this problem than a list of the devices that do. (Anyone know of such a list?)
