The old card has similar weird issues. It actually hangs as soon as i unplug the USB cable, even.

It also can't bootstrap after a factory reset: it can't seem to connect to kobo to get updates and aborts (and suggests downloading the desktop app, ugh).

Well now the problem is i can't even test that because I can't boot the darn thing.

I can confirm the "20 seconds poweroff" does not work.

There's something really strange. Even with the old stock sdcard, when i plug in the USB power, it works fine, but then as soon as i unplug it, the backlight goes out, and the entire machine hangs.

Could this be a power issue?
