osm0sis is currently trying to fix this for the DirtyV kernel: http://forum.xda-developers.com/gala...13655/page1150
Now I know why converting /data didn't work while cache was no deal at all. Was thinking what the hell I'm doing wrong and didn't remember that I encrypted once some time ago... Not even fastboot erase or format did help. Is it normal that I NEVER have to enter the encryption password? I read at boot should be the normal behavior but not for me^^ thx @osm0sis for addressing it though
