So using the docs to change the kernel will make it unbootable.

You are confusing things. Please, don't mix Ubuntu 19.10 Image with Ubuntu 20.04 LTS. Kernel modules are in /usr/lib/modules, use the latest Image: https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/releases/tag/v3.10

Flash v3.10 in a new sd card....

Flash v3.10 in a new sd card.... Formatted and flashed using your scripts two times, just to be sure.

There is no such files in v3.10 like you printed here:

Here is the content of the /boot partition if you flash to a new card: 2021-08-25-213411_1920x1056_scrot

Turns out that the flash part was not writing to the boot partition, hence old kernel, modules mismatch, wifi issues. I manually mounted the boot partition and copied the files. Working fine since, even wifi (except channels over 11, even though I changed the region).

rlesac commented 3 years ago

It's a weird error, so you might wanna add some basic checks in the flash script.
