Did a clean install (and cache clean), at first it seemed to work, but after installing all my apps and rebooting, I'm getting a bootloop. I saw a screen saying system UI had crashed once, but now I don't get that far anyomore.

I also had some problems flashing TWRP.
The flashing always seemed to work, but when I entered recovery, I was met with the black screen with a phone and a cable on it.
When I rooted the phone, and used flashify to flash TWRP it finally worked.
