Here is the solution.
I successfully returned to new dashboard after performing this steps:
delete from OS_PROPERTYENTRY where entity_key ='user.features.enabled' OR entity_key ='confluence.user.runtime.recent-changes.size' OR entity_key='confluence.macros.dashboard.selected.tab';
Query OK, 56 rows affected (0.08 sec)
# /etc/init.d/confluence restart
update confluence web page and login again
Just found a solution for my problem.
and then follow section "The default getting-started section" (reset default for global layout).
