In other words: It looks like the on-device boot loader is screwed up. This can only be fixed manually, and probably only through serial debricking. Don't ask me how though, I've never done anything like that.

The on-device boot loader is in hardware, write-protected, flash.
Very hard for the end-user to screw up, although they can if they try hard enough.

I would suspect a more general hardware failure than a corrupted u-boot image. (Unless the O.P. did something they are not admitting to now.)
I have never replaced the on-device u-boot image, only read about doing it (in Amazon's u-boot source code).
So, sorry, I can't be of any help with this one.
