Update seems to have bricked the phone. Process of installing went fine until it rebooted and showed Jolla logo, after that stays black and no response to anything. Pressing again shows the red light (turning power off?). If powering again -> vibration and jolla logo -> then total blackness as described. Had the latest update before this. Factory reset?

Seems to be more cases of the same kind in the "2gether.jolla.com release notes"-topic.
