I can enter the Recover Mode this way:

- Switch phone off
- Press Vol+ and Power Button
- as soon as the "SAMSUNG" appears release both buttons
- as soon as the "Android out of the Box" appears, press the Menu button.

Remark: Don't press the Home Button during power on! Otherwise you will enter the RAM Dump mode.
