I have found the cause of my problems. I'm writting it here maybe it will help someone.

Some stock roms for p905 that can be found on sammobile and samsung firmware sites have issues. I have chacked polish and british roms and they have "odin: invalid ext4 image" error (the consequence of it is samsung keybord not working, force closes), Now I have installed rom from greece, it's flawless

Thank You for Your help.
