I started the normal update process, through Settings, which said finished after an hour with "Cannot update at the time". The device remained in a weird state. When turned on, it will show the Jolla logo, load for a while then turn black. WLAN connects automatically and SSH is on, so I could connect to the phone.

I tried this:

# systemctl --state=failed
UNIT                           LOAD   ACTIVE SUB    DESCRIPTION
mount-sd@mmcblk1.service       loaded failed failed Handle sdcard

systemd-tmpfiles-setup.service loaded failed failed Create Volatile Files and Directories
user@100000.service            loaded failed failed User Manager for UID 100000

I tried version --dup too:

# version --dup

Obviously, version --dup needs a user session to login to the Jolla server. I tried systemctl start user@100000, which won't work without devel-su (and I forgot the password).

What can I do, other than a full reset? Can I somehow retrieve my password and manually start a user session? Note that I connect to SSH with keys, not with password.

EDIT: I manually changed the devel-su password in the recovery mode shell. Now I have access to better logs. This comes from journalctl -xe, after running systemctl start user@100000:
