Dying mid-upgrade shouldn't result in missing files; updates are purely additive. I don't remember the exact details, but this situation might be possible if shutting down during a hard factory reset.

Anyway I tried performing a manual factory reset as described in https://wiki.mobileread.com/wiki/Kob...Aura_Edition_2 but so this does not seem to do the trick.
Is checking the button combination for factory reset something that is handled by the nickel application, or is it handled by uboot (or maybe something even more low level?) .
In the former case I guess it is pretty logical it does not work, in the latter I need to retry a bit more.

Last I checked, it is handled in the early init script.

In the former is there is a chance i get it working again with the procedure described in https://www.mobileread.com/forums/sh...d.php?t=289206 ?
(there is no image for the aura but I read in another thread that ppl have success with the N250 Aura H2O image on the aura).
Or if there are suggestions for an alternative method, since I have root access I am guessing there should be a way to get it up and running again ?

If you have root access and no sd card image, first
take a sd card image (at least of the first few tens of megabytes, preferably also the recovery partition too, or even the whole thing) so you have one.
See if you have a working recovery partition. In there is a fs.tgz file which contains the initial contents of the system partition. If you're lucky, you should be able to just extract that over the system partition, then extract an upgrade over it after.
