I tried a third time to upgrade.
First I tried @Roboe’s suggestion:[quote=“Roboe, post:190, topic:29656”]
- Uninstall Xposed.
- Boot into your clean system and upgrade to Marshmallow
- Boot into Marshmallow and make sure everything works as expected (if not, refer to the bug linked on the top)
- Install Xposed Framework for Marshmallow (SDK 23)

Of course, I got stuck at step 3 and couldn’t solve that bug. Then I followed the suggestion by @freibadschwimmer:
That kind of worked. At least the first part. I had a functioning clean version of Android 6 without my data on it. It did get stuck in the setup wizard, though. I couldn’t log in to my google account, it just delivered the same pop up regarding logging in over and over. I could break temporarily break out the setup wizard, by just swiping down and go into settings. That worked fine and while the functionality was quite limited, it was stable. So not usable, but at least no freezing or rebooting. Then I tried to restore my data through TWRP and: did not work! I ended up in an eternal boot process and it nearly looked like I bricked it as booting into recovery only worked half the time.
No matter what I’m trying, I always end up with an unusable phone. Luckily, I’m back on Android 5.1 with all my stuff, including various minor bugs I was hoping to vanish with Marshmallow, but it certainly looks like I’ll be stuck with Lollypop for some more time now!
