Answer 2

only from a flash drive or from a Time Machine backup.
I found how to rollback to OS X Mavericks 10.9 from OS X Yosemite 10.10 - you need to go to the App Store and click on "purchases", then scroll down and see the Mavericks we previously installed))
After download and install from the USB flash drive clean. In this case, everything must be previously saved.
