Ok. After 24 hours everything is working great. Maybe even better than on MM. I like it so far. The dark themes are ok, but changed back to light, because they were not enough minimalistic for my taste. And the notifications did stay white, which defeats the purpose in my opinion.
As for the install. I had huge problems. On the first try I probably got a bad download and I got an error on 21% of the install. After that it only booted into download mode. I tried a few times it always stopped at 21%. Tried to use 10i kdz to go back, got the same error, but on 15%.
Luckily LG Bridge detected the phone and I could repair my install through it. Everything was back to normal MM after that.
Tried again with the fresh install and this time it went without problems. I could not do refurbish mode, because I got an error, but an update. And after the first reboot it detected my data, but said it was corrupted and it said I have to do a factory reset. After that the phone booted without problems.
I think it has something to do with boot up pattern lock I use for data protection, so you should probably disable that before the flash.
