At the moment there is no music on the player. When I reboot the player it say's End of playlist.

You should be able to select a playlist and it should play music. Even if the database is damaged a bit. It's normal for it to say "end of playlist" after a synch.

Press the bottom button on the unit's face three times. It should start playing the whole unit.

Is there a tool, which erase everything on the hole disc, including partition and then creates it as if the player was new?

Yes. It can be found at the Empeg download page under utilities. There are no instructions there on how to use it, but you can glean the necessary information from this FAQ item.

But you shouldn't need to format the disk. The database is very good at self-repairing and you should be able to use the unit without having to start over again. Try performing some more synchs and see if you can force the database to repair itself.
