ozlacs, in my opinion you should start from scratch: flash 9.0 firmware, perform full wipeout, and then flash this rom.
I've tried partial flashing like described a couple of posts ago, or changing roms without total wipe - and always it resulted in some bizarre system behaviour. I'm on this AICP right now, and it started to work flawlessly just after flashing 9, format, and then flash rom. Before that strange things happened: the screen woke up without any reason, device hang from time to time - stuff like that.
My advice: get some free time, make backups - and up up in the waaay!
You should be pleased with results.
@marcost22 :
battery consumption stabilized on 4% per night on my device. Which is not awesome, but acceptable
Great job with this rom - it is fluent, looks great, no hickups and any misbehaviour - thanks for your work!
