so all in all we are in 2020 and this is pretty ancient but I see no reason why not to use the good hardware.

I want to explore my options.

do I find some more updated android firmware that is documented to not brick this box and install it?

or do I try out an alternative os? I understand that this is not a regular pc therefore if I want ubuntu I heard that armbian is my option.

those are my only 2 options, right?

I just want something that is similar to android or ubuntu-desktop and that is stable, works well, relatively modern and not from 2015, and that will not brick my box.

can this thing boot from an external sd card or external usb hard drive?

Any recommendations as well as os installation tutorial links will be greatly appreciated! :)
