Thanks, I did it before but the calendar is still in the update list. Then I went to the system/app/ and I saw that the name of my calendar is CalendarGooglePrebuilt, then I added a line and type Calendar Google Prebuilt and flash the zip again and it works!Just remove the comments from those two as well as the other theme apps you flash.
Here's an example, theme ready apps, calendar and keep will be detached.
May this will help someone
