I've been able to dirty flash from 11.2.0 to 11.3.0... Not to 11.3.1 cause I've been rom hoping... But i only have some minimal apps i use though. Good luck!I like this ROM a lot but having to wipe data with every update is a big inconvenience.
As a seperate post...
Is the extra bright screen after a few minutes with the screen off is going to get fixed? Haven't noticed the rotated screen bug when unlocking the phone either at least
Edit, yup still has the rotation and increased brightness "issues", still this rom is amazing and i can overlook them a bit
