Update went without issues, CODI update went through on second try (didn't bother with offline mode or anything).
Can confirm the vertical bar on the left side for the rooted image, but at least SIM access is working, so I guess that's an improvement. I'm currently booting into the rooted image only for larger changes, but for daily use don't really need it, so I just hope they fix it - and for when I do need rooted access at least it's better than before.
