Yes, I've tried every possible methods of reset (that I know of and that Kobo suggested). But no reaction at all, neither to the pinhole reset (plugged in or unplugged) nor to the forced factory reset.

It's a beautiful brick.

Since there's only the black "Restarting" screen there's no way to try WiFi or anything else.

There's no LED when plugging the Kobo in either. No change on the screen, no trying to connect to my computer... I guess the update bricked my brand new Aura for good.

But hey, I got so see some "Update" and "Connected" and "Restarting" screens in high resolution - and a very boring completely black "Powered Off" screen (wonder why they ditched the smiling and sleeping Kobo).
